Nippon Precision Circuits Inc. announces the mass production run of SM8224CM, a receiver and decoder IC that supports the Bellcore TR-NWT-000030 and SR-TSV-002476 standards calling number identification (caller ID) and call waiting dual-tone signals.

The SM8224CM has separate caller ID signal and call waiting signal inputs, which allows the gain for each input to be adjusted independently. It is fabricated in CMOS and features a power-down function, realizing low power dissipation operation.

The SM8224CM supports "Calling Number Identification and Call Waiting Service" which is now serviced in the North America and will have been serviced in Asia.
