zhx1423 sir ultraslim transceivers ps024903-1005 1 description the zilog zhx1423 for pdas, internet appliances, medical electronics, and gen- eral-purpose interactive handheld devices is the smallest, lowest power, and high- est functional standard-power (0?1 meter minimum range) transceiver available. the zilog zhx1423 features exclusive alwayson tm technology that allows the transceiver to ?listen? for an irda communication at a typical current of 6 a, allowing the default mode to be left on with negligible effect on the battery life. 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. a pplication circuit space is also minimized because only two external components are required. the zhx1423 is designed to support irda-data sir mode (115.2 kbits/s) and pro- vides typical data links with other standard-power irda transceivers up to 1.0 meter away. the transceiver combines an ired emitter, a pin photodiode, and a unique driver/control asic in a single package, as shown in figure 1. figure 1. zhx1423 block diagram the zilog zhx1423 also features a shutdown control that minimizes current draw to 0.1 a typical.
