Hardware Description14 98-08901C64-O•When the power supply is lower than 2.85 V, the g20 software determines that the battery is low and disconnects the unit.•When the voltage is greater than 4.25 V, the g20 software detects an over voltage condition and does not allow the unit toestablish a call.•The VCC line typically drops during TX periods.Figure 6. VCC Signal During TX PeriodsTo minimize the ∆, it is recommended to use lines that are as short as possible, and to place a 1000uF capacitor (or the maximumpossible) in the g20 VCC input. (When a battery is used, there is no need for a large capacitor.)It is recommended to keep the ∆ less than 0.3 V.3.2.1.1 Power Supply RF FilteringIt is recommended to add RF filtering to the DC lines.Use 100nF, 39pF, 22pF or 8.2pF capacitors in parallel to the power supply lines (close to the g20 connector). MUST ALLTHESE CAPACITORS BE USED IN PARALLEL? OR SOME COMBINATION?3.2.2 G20 Current Consumption In order to design the power supply correctly and to calculate the battery life, you should take into account the currentconsumption of the g20 when operating in different modes.NoteThe power supply should be able to drive at least 2.5 A.Table 4. g20 Current ConsumptionMode Current Consumption (mA RMS)g20 in Sleep mode (camped and Sleep-mode enabled) < 2.5 mA, RMS @ DRX9, Typical 2.2 mA< 4.5 mA, RMS @ DRX2, Typical 3.5 mAg20 during search time < 40 mA, RMS, Typical 25 mA, RMSg20 off < 100 uA – Typical 25 uAg20 during a callGSM 900 @ Power level #5 < 350 mA, Typical 270 mA@ Power level #10, Typical 160 mA@ Power level #19, Typical 135 mATX TX TXTransmit PeriodsVCCDRAFT 1 (31.3.03)
98-08901C64-O 15Hardware Description3.2.3 Turning the Unit On/OffTwo different mechanisms are available to turn the g20 on and off:•On/Off signal (Pin 53)•Ignition line (Pin 51)3.2.3.1 On/Off SignalAfter power is applied to the g20, the on/off signal is pulled high to the VCC by a 200kΩ resistor.To turn the g20 on, the on/off signal should be pulled low for a minimum of 700 ms.After the g20 is turned on, the line should be pulled low for a minimum of 1.1 seconds to turn it off. The unit can be turned offonly if at least seven seconds have elapsed since turning it on.Figure 7 shows the timing diagram for the on/off signal.Figure 7. On/Off Signal Timing DiagramIn Figure 7, the following timing requirements apply:•T1 minimum = 0.7 seconds.•T2 minimum = 7 seconds.•T3 minimum = 1.1 seconds.GSM 850 @ Power level #7 < 250 mA, Typical 185 mA@ Power level #10, Typical 160 mA@ Power level #19, Typical 135 mADCS 1800 @ Power level #0 < 300 mA, Typical 220 mA@ Power level #10, Typical 160 mA@ Power level #19, Typical 135 mAPCS 1900 @ Power level #5 < 300 mA, Typical 240 mA@ Power level #10, Typical 160 mA@ Power level #19, Typical 135 mANoteDRX2/9 is the rate used by the base station to query the mobile station.

Hardware Description16 98-08901C64-O3.2.3.2 Ignition LineWhen the g20 ignition line is held at a high level, the g20 is turned on. When this line is pulled low, the g20 is turned off. Inorder to protect the line from voltage bounces, the g20 is tuned off only if the line is held low for at least 500 ms.The high input to the ignition line must be greater than 2.75 V. The line can tolerate up to 40 V.After the g20 is turned on, the application should wait for DSR before sending data to the g20. The DSR becomes active loweight seconds after the start of T1, or after the ignition line is pulled high. DSR is only valid with UART, and is not valid withUSB.3.2.4 Sleep Mode OptionsThis section describes how the g20 can be awakened by the DTE and vice-versa.The DCE (g20) and the DTE can incorporate a sleep mechanism in their application in order to conserve battery life.Sleep mode enables the g20 to be awakened when the DTE wants to communicate with it. Conversely, it also enables the DTEto be awakened by the g20 when the g20 wants to communicate with it. 3.2.4.1 General•The g20 Sleep Mode option can be enabled or disabled using ATS24. •Sleep mode is activated by sending ATS24 = n, where n = 1, 2, 3 or 4 seconds. (To disable Sleep mode, send ATS24=0.) •The g20 drops the CTS (h/w Flow Control) when it is in Sleep mode. •The g20 does not enter Sleep mode when data is present on TXD or RXD lines.•At the end of the TXD (meaning, the TXD buffer is empty), the g20 waits n seconds (as defined in ATS24 = n) before enter-ing Sleep mode.•The DTE uses CTS to send data only when the g20 is awake. The DTE waits when the g20 is in Sleep mode.•The DTE should drop RTS during the sleep period in order to prevent the loss of data sent by the g20.Figure 8. CTS Sleep Mode TimingDRAFT 1 (31.3.03)

DCE/DTE ConnectivityWaking Up the DCE:The following apply when waking up the DCE:•The Wake-up In line is used to awaken the g20. This input is routed into an Interrupt in the g20.•Whenever the Wake-up In line is at logic “low”, the g20 remains in an awake state.•When the DTE needs to send data, it should activate this line, wait 30 ms (the wake time required for the g20), and then startsending the data.•While the DTE is sending data, the wake-up line should remain low, so that the g20 does not enter Sleep mode.Figure 10. Waking Up the g20 when the DTE Wants to Send DataWaking Up the DTE:The following apply when waking up the DTE:•The g20 uses the Wake-up Out line to indicate to the DTE that data is present. •The DTE should not enter Sleep mode when the Wake-up Out line is low.•When the g20 has data to send to the DTE, it drops the Wake-up Out line to low.•The g20 will send the Wake-up Out line #ms to low, as indicated by S10x in Figure 11.DTE TXDWake up In line30 ms 30 ms 30 msDRAFT 1 (31.3.03)
Hardware Description18 98-08901C64-O•While the g20 is sending data, the Wake-up Out line remains low. •After the sending of data is completed, the g20 brings the Wake-up Out line to high.•The DTE should keep RTS off during this sleep period in order to avoid sending data when it is not ready.Figure 11.

SIM signals are routed to the interface connectorand include all the functionality required for SIM card operation.3.3.3.1 SIM ConnectionFigure 16 shows a g20 SIM connection:Figure 16. g20 SIM Connection48441-4SIMDriver6.8V Zenerswith lowCapacitanceFor ESD protection1uFG20DRAFT 1 (31.3.03)
Hardware Description22 98-08901C64-OThe following apply for g20 SIM connections:•The g20 passes all SIM ETSI tests when an external socket is connected to the g20 with lines shorter than 10 cm.•Longer connections require SIM testing to be performed in the user application.•The g20 can work with 1.8 V or 3 V SIM cards.•The g20 provides ESD protection for the SIM lines (6.8V Zener diodes with low capacitance), and for 1uF capacitors to theSIM VCC.•The SIM_PD (SIM Present Detect) signal is active when it is pulled low.3.3.4 SPIThe SPI is a standard microprocessor bus used as a g20 debugging port. This port activates a debug option that enables logs tobe taken from the g20 while it is operating. It is recommended that this bus be accessible in the user application. In the g20Developer’s Kit, the SPI is driven to an SPI/RS232 interface. The SPI is then converted and uses the RS232 port for debugging.In the g20 Developer’s Kit, the SPI bus is converted to an RS232 protocol using a special interface circuit. It then uses thestandard RS232 port for debugging. Table 5 shows the pins available on the SPI bus.3.3.4.1 SPI Connection3.3.5 Unique g20 InterfacesThe g20 features certain unique functions (pins) that may be required by selected user applications, such as TX_EN, AntennaDetect, GPRS Detect and Entertainment Mute.

98-08901C64-O 23Hardware Description3.3.5.2 Antenna DetectThis pin indicates whether or not the antenna is inserted. This option was requested by a specific customer and was preparedspecifically for their board layout. Thus, this option is not supported by the basic g20 models.The antenna-detect circuit detects whether the impedance of the antenna is 100 KΩ or lower. The antenna must have a resistanceto ground of less than 100 KΩ. in order to be detected. Figure 18.

Hardware Description24 98-08901C64-O3.4.1.2 Analog OutputThe g20 has a differential speaker output and an alert output:•Speaker output: When headset mode is used, the headset speaker should be connected to the SPKR_N signal of the g20.When a differential amplifier is used, both lines should be connected. An 8-ohm speaker can be connected directly to thespeaker lines.•Alert: The g20 supports a direct connection for an alert transducer, in order to build a handset from the g20. All the soundsthat are transmitted to the alert can be routed to the speaker using the appropriate AT command.Table 6 shows the SPKR_N output in headset mode for different network signal levels when the g20 is set to the maximumvolume level and the headset interrupt is pulled low.The measurements shown in Table 6 apply in the following configuration:Figure 20.

If a microphone with a different voltage isused, the bias should be as clean as possible, and referenced to MIC_GND. Because most GSM buzz (217Hz TDMA noise)is generated from the microphone path, if a different bias is created, it should be filtered to supply DC only.•The MIC_GND and GND are connected inside the g20 and should not be connected to the application board.•Keep the lines of the microphone inputs as short as possible. To filter the lines from RF emission, 39pF capacitors can beused.•The g20 GND should be connected on all four pins, with two mounting screws to the application ground.•If possible, the RF cable ground from the g20 should be connected to the GND of the g20.•The digital lines of the application should never be referenced to the MIC_GND.3.4.2 Digital Audio InterfaceThe g20 digital audio interface is a full-duplex SAP (serial audio port) comprised of four signals:•PCM_FS: This pin is used for frame sync output provided by the g20.•PCM_CLK: This pin is used for the clock output provided by the g20.•PCM_DIN: This pin is the serial input to the g20 SAP.•PCM_DOUT: This pin is the serial output of the g20 SAP.The following conditions apply to the digital audio interface of the g20:•The g20 SAP works in network mode, with four slots in each frame. Each slot consists of 16-bit data.•The frame sync rate is 8 KHz, and the clock rate is 512 KHz. •The g20 is the master in the SAP network. Therefore, the connected DSP should be configured as the host.Table 11. Alert Transducer Levels for the ALERT_P SignalHandset Volume ALRT_P010711532206330544245600685071200DRAFT 1 (31.3.03)
