资 源 简 介
The PCD5003A is a very low power decoder and pager
controller specifically designed for use in new generation
radio pagers. The architecture of the PCD5003A allows for
flexible application in a wide variety of radio pager designs.
The PCD5003A is fully compatible with “CCIR Radio
paging Code No. 1” (also known as the POCSAG code)
operating at data rates of 512, 1200 and 2400 bits/s using
a single oscillator crystal of 76.8 kHz.
In addition to the standard POCSAG sync word the
PCD5003A is also capable of recognizing up to 4 User
Programmable Sync Words (UPSWs). This permits the
reception of both private services and POCSAG
transmissions via the same radio channel.
Used together with the Philips UAA2080 or UAA2082
paging receiver, the PCD5003A offers a highly
sophisticated, miniature solution for the radio paging
market. Control of an RF synthesizer circuit is also
provided to ease alignment and channel selection
