PAGING DECODER IC (POCSAG)

The S-7038AF decoder IC is for use in the CCIR* RAdio Paging Code Number 1 (POCSAG** code). It processes internally the POCSAG signals for the Tone-only pager. Furthermore, decoded data is transferred to an external microprocessor, so the S-7038AF can also be used for a Display pager. Eight kinds of call-tone cadences generated for valid calls and messages received let user know which information is received. The S-7038A has a battery saving function that drives the signal receiving circuit intermittently.

Functions

● Power-on clearing

● BCH correction up to 2 bits

● Battery saving

● Battery low alert

● Memory (for Tone-only pager, 4 channels)

● Expansion
