zhx1403 sir ultraslim transceivers ps014509-1005 1 description the zilog zhx1403 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 zhx1403 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 (s ee figure 1). application circuit space is also minimized because only two external components are required. figure 1. ultraslim form the zhx1403 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 2. figure 2. zhx1403 block diagram the zilog zhx1403 also features a shutdown control that minimizes current draw to 0.1 a typical.
