Description
The ZILOG ZHX1820 is a low-profile version of ZiLOG’s popular ZHX1010 1-meter transceiver. Packaged in the “top-look” configuration (that is, the lens axis is perpendicular to the mounting surface), the transceiver is mechanically enhanced for ultra compact, power-conscious portable products, such as portable printers, handheld computers, and personal data assistants (PDAs). Designed to operate using the IrDA-Data mode, the transceiver combines an infrared emitting diode (IRED) emitter, a PIN photodiode detector, a digital AC coupled LED driver, and a receiver/decoder in a single package.
