The ZiLOG ZHX1200 is the transceiver of choice for mobile communication applications in today's ultra compact, power-conscious, portable products, such as mobile phones, pagers, or personal data assistants (PDAs). Specifically designed to support Infrared Data Association (IrDA) IrMC low-power SIR (serial infrared) mode, the ZHX1200 combines an infrared emitting diode (IRED) emitter, a PIN photodiode detector, a digital AC-coupled LED driver, and a receiver/decoder in a single, miniature package.
The ZiLOG ZHX1200 provides an efficient implementation of the low-power SIR standard in a small footprint format. Application circuit space is also minimized, as only one capacitor is required to complete the solution.
