FSK Decoder and DTMF Receiver IC

OVERVIEW The SM8223A is a FSK (Frequency shift keying) decoder and DTMF (Dual tone multi-frequency) receiver IC. It is fabricated using a CMOS process and features a power-down function for low power dissipation operation. The FSK decoder and DTMF receiver have the same performance characteristic

Dual-Tone Receiver IC

OVERVIEW The SM8224C is a receiver and decoder that supports the Bellcore TR-NWT-000030 and SR-TSV-002476 standards calling number identification (caller ID) and call waiting dual-tone signals. It has separate caller ID signal and call waiting signal inputs, which allows the gain for each input
