    Part 22 and Part 24. This includes Electromagnetic Energy Exposure (EME) testing. As the c18 modem is not a standalone trans- ceiver but is an integrated module, the c18 cannot be tested by itself for EME certification. It is, however, the integrator’s respon- sibility to have the completed device tested for EME certification.

  • Page 19: Safety Precautions

    Introduction Systems using the c18 are subject to mandatory EMC testing under directive 89/336/EEC. Other directives, such as the LVD directive 73/23/EE, may also apply to a system using the c18 module. SAFETY PRECAUTIONS c18 modules are not ESD protected. ESD preventive measures must be taken when handling the modules.

  • Page 21: Hardware Description

    Figure 3. c18 Block Diagram The c18 is a cellular radio based on the Qualcomm MSM5100 chipset. The call-processing protocol and the voice DSP are located within the Baseband block. The RF block transmitter and receiver support 800/1900MHz CDMA and 800MHz AMPS.

  • Page 23: Figure 5. Baseband Block Diagram

    Hardware Description 3.1.2.3 Frequency Generation There are three RF frequencies generated to enable frequency conversions within the radio: • Front-end-down and Front-end-up Conversion LO Frequency: The frequency plan is designed so that the Rx front-end-down conversion LO and the Tx front-end-up conversion LO are the same frequency, which is generated in the dual synthesizer IC.

  • Page 24: Power Supply And Current Consumption

    (models with a 70-pin or 36-pin interface connector), or via two VCC and two GND pins (models with a 28-pin connector). The source voltage must be between 3.6 V DC and 4.5 V DC (4.0 V nominal) on the c18 interface connector pins (across the VCC and GND pins).

  • Page 25: Current Consumption

    In order to correctly design the power supply or battery for the c18, integrators should take into account the current consumption of the c18 in its various operating modes. The c18 is a CDMA phone that transmits in continuous mode. Table 6 lists the maximum current for each mode supported by the c18 module.

  • Page 26: Turning The Unit On/Off

    Turning the Unit On/Off Using the AUDIO_OUT_ONOFF Pin The c18 module can be turned on or off using the AUDIO_OUT_ONOFF line (pin #53 on the 70-pin connector, pin #14 on the 36-pin ZIF connector and pin #17 on the 28-pin DIN connector). The AUDIO_OUT_ONOFF line has dual functions, as follows: •...

  • Page 28: Turning The Unit On Using The Ignition Pin

    Note The Ignition line is used to turn on the c18 unit, and is primarily used for units connected to a mobile device, where current consumption is not a major concern. When the Ignition line rises, the unit turns on. The Ignition line is also used to turn the unit on when power is connected to the unit (for example, the Ignition line in a car kit).

  • Page 29: C18 Exiting From Sleep Mode

    3.5.2 c18 Exiting from Sleep Mode When the c18 senses communication activity on its Rx data line, it exits Sleep mode. Entering Sleep mode again depends on the activity of the network and the activity of the RS232 lines. INTERFACES c18 modules have one or two female MMCX RF connectors (J30 and J31) and an external interface connector.

  • Page 32: Uart1

    Figure 11. UART1 Interface UART signals are low CMOS-level signals (0 to 2.8 V) that can be connected directly to the host UART. c18 input signals (such as TXD, RTS and DTR signals) are buffered, making them capable of receiving signal levels up to 5.0 V. Signals are referenced to the GND.

    RS232 transceiver. In order to configure the c18 to communicate through UART1, RS232 mode or RS232 + USB mode should be selected by setting the configuration pins (OPT1, OPT2, AUDIO_IN and USB_VBUS). See “c18 OPERATING MODES” on page 17.

  • Page 34: Usb

    Removable-User Identity Module (R-UIM) Interface The c18 has optional internal and external R-UIM interfaces. Two R-UIM signals (UIM DATA and UIM CLK) are shared with UART2 signals (RXD and CTS). For this reason, only one of these interfaces can be used at a time. The interface supports 3V cards.

  • Page 35: Table 10. Internal R-Uim Pinout (J101)

    UIM_PWR (UIM_VPP) Programming voltage It is recommended that the total trace length between the board-to-board connector pins on the c18 and the pins of the external card holder not exceed 100 mm. Before removing the SIM card or inserting a new one, ensure that the c18 module has been powered down. (See “Turning the Unit On/Off”...

  • Page 36: Audio Interfaces

    These interfaces are internally muxed. Therefore, only one interface can be active at a time. The hands-free (auxiliary audio) interface is available for all three types of interface connectors. The handset and headset interfaces are supported only on c18 models that use the 70-pin connector.

  • Page 37: Handset Interface

    3.7.1 Handset Interface This differential interface is intended for handset-like applications. The c18 module contains all biasing circuitry. Therefore, no external components are needed, except for an active condenser microphone and a 32Ω earpiece. Figure 14 shows the handset interface with biasing circuitry:...

  • Page 38: Headset Interface

    An optional (normally closed) switch can be used for answering/ending (SEND/END) an incoming call from the headset. The c18 monitors the HEADSET_MIC signal DC level, in order to define the state of the SEND/END switch. Be sure to pull down the microphone input when the headset is unplugged from the c18.

    The KEYB_DRV output is intended to be a driver for backlight LEDs in handset-like applications. KEYB_DRV is an open drain output used to sink the current. Therefore, the backlight LEDs’ anode should be tied to VCC and the cathode to the c18 KEYB_DRV pin.

  • Page 43: Figure 19. Keyb_Drv Output Connectivity

    BL_SINK The c18 BL_SINK output is an open drain current sink. Therefore, the LEDs’ anode must be tied to VCC and the cathode to the c18 BL_SINK pin. The programmable current sink operates between 0 mA and 40 mA in 16 steps through the SBI register DRV_LCDSEL.

  • Page 44: Lcd_El_En

    General-purpose A/D Converter - GPADC The c18 has two general-purpose ADC inputs, ADC1 and ADC2. The GPADC is located in the MSM5100 block. It is intended to digitize DC signals corresponding to analog parameters, such as battery voltage and temperature.
