SIR UltraSlim Transceivers

Description
The ZILOG ZHX1223 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 ZHX1223TB features only the low receive current consumption of
90 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. Application circuit space is also minimized
because only two external components are required.
The ZHX1223 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 1.
Figure 1. ZHX1223 Block Diagram
The ZILOG ZHX1223 also features a shutdown control that minimizes current
draw to 0.1
µA
typical.
