P R E L I M I N A R Y 2 5 5 5 6 7 ZHX1203 SIR UltraSlim Transceiver (IrMC) 1 Description The ZILOG ZHX1203 for mobile phones, pagers, and PDAs is the smallest, lowest power, and highest functional transceiver in its class. Communication takes place at the low receive current consumption of 100 µA (typical). The ZHX1203MB features only the low receive current consumption of 100 µA (typical). The UltraSlim form factor (7.3 mm long x 2.8 mm wide x 1.9 mm high) allows placement in virtually any small device (see Figure 1). Application circuit space is also minimized because only two external components are required. Figure 1. UltraSlim Form The ZHX1203 is designed to support IrDA-Data SIR mode, which at 115 Kbits/s provides the capability for the user to share phone numbers, addresses, and notes as well as linking a PC to the internet via a mobile telephone. The transceiver combines an IRED emitter, a photodiode, and a unique driver/ control ASIC in a single package, as shown in Figure 2. The ZILOG ZHX1203 also features a shutdown control that minimizes current draw to 0.1 µA typical. Figure 2.

The pins are described in this section. Table 1. ZHX1203 Transceiver Pin Out Pin Name Function I/O 1 NC NC (future use) — 2 VCC Supply voltage — 3 GND Ground — 4 SD Shutdown I 5 RxD Receiver output O 6 TxD Transmitter input I 7 LEDA IRED anode — — TAB Shield connection — VCC Positive Supply (Power) Connect to positive power supply (2.4–3.6 V). Filter with a 1.0-µF ceramic bypass capacitor and terminating resistor as close as possible to the VCC pin. PS016402-1102 P R E L I M I N A R Y ZHX1203 SIR UltraSlim Transceiver (IrMC) 3 GND Ground (Power) Connect to ground of the power supply. A solid ground plane is recommended for proper operation. SD Shutdown (Input, active high) This input is used to place the IC into a shutdown mode. TxD needs to be driven low to achieve low shutdown current. RxD Receive Data (Output, active low) This output provides received serial data. It is a tri-state, slew rate controlled CMOS output (tri-stated during shutdown) driver capable of driving a standard CMOS or LS series TTL load. No external resistor is required. TxD Transmit Data (Input, active high) This CMOS input is used to transmit serial data and has an internal pull-down resistor that is enabled only during shutdown. LEDA LED Driver (Power) This output is internally connected to the LED anode and contains an internal current source. The voltage range on this pad is 2.1–4.2 volts. TAB Shield Connection The shield tab must be soldered to ground for proper operation.
