General Description
The HT9142 is designed for FM communication system
devices. It combines a paging system, mixer, IF limiter,
Quadrature detector, operation amplifier, comparator
and more. The HT9142 could provide the customer s
PAGER system with total solution along with Holtek s
POCSAG Pager Controller series products.
The HT9142 can also use on Holtek s RF key-
board/mouse applications.
