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
