The ZILOG ZHX3403 for mobile phones, pagers, and PDAs is the smallest, lowest power, and highest functional transceiver in its class.
The ZiLOG ZHX3403 features exclusive AlwaysOnTM technology that allows the transceiver to "listen" for an IrDA communication at a typical current of 6 µA, allowing the default mode to be left on with negligible effect on the battery life. Once another IrDA device has been discovered, communication takes place at the low receive current consumption of 100 µA typically (MIR).
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 of ZHX3403 is also minimized because only two external components are required.
