ZHX1820
Slim SIR Top Look Transceiver
1
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.
The ZILOG ZHX1820 provides an efficient implementation of the SIR standard in
a small-outline footprint format. Application circuit space is also minimized, as only
three components are required.
ZHX1820 also features an independently controlled shutdown that minimizes
current draw to a maximum of 1 µA.
