Advance Information
MC68176 2-BIT A/D CONVERTER IC
This document contains information on a new product. Specifications and information herein are subject to change without notice.
The MC68176 chip is part of a total solution available from Motorola for providing FLEX
paging capabilities in a low-power, low-cost system. Working in conjunction with standard
paging receivers, the MC68176 takes the 4-level baseband audio signals from the receiver and
performs 2-bit A/ D using 8-bit DACs for peak and valley detection, passing the 2-bit digital
signal directly to the MC68175 FLEX chip or MC68181 Roaming FLEX chip for further decoding
and FLEX protocol handling. Received messages are then passed to the host microcontroller or
microprocessor via the Serial Peripheral Interface (SPI). The host processor (running
FLEXstack software) interprets the data appropriately (as binary, alphanumeric or numeric
message types), and handles all I/ O and user interaction functions.
The FLEX paging protocol is the multi-speed, high-performance protocol adopted by leading
service providers worldwide. FLEX protocol gives service providers the increased capacity,
added reliability, and enhanced pager battery performance required today. It also provides an
upward migration path to the service provider which is completely transparent to the end user.
