PAGING DECODER IC (POCSAG)

The S-7040D decoder IC is for use in the CCIR* RAdio Paging Code Number 1 (POCSAG** code). The S-7040D can be used for display pager since it processes the POCSAG signals internally and sends the decoded data to an external microprocessor. Furthermore, decoded data is transferred to an external microprocessor, so the S-7040D 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-7040D has a battery saving function that drives the signal receiving circuit intermittently.
