NIPPON PRECISION CIRCUITS INC.
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 characteristics as dedicated ICs that perform the same functions, with the added beneļ¬t 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-relat...
