FSK Decoder And DTMF Receiver IC

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 opera- tion. The FSK decoder and DTMF receiver have the same performance characteristics as dedicated ICs that perform the same functions, with the added benet of an FSK decoder/DTMF receiver auto-select function1 using the telephone tip/ring input signal. It also features a ring (call signal) signal detection circuit, making for easy construction of low power dissipation, high-performance Analog telephone-related applications. By Seiko NPC Corp.
