1 / 15 page SM8222A/B NIPPON PRECISION CIRCUITS—1 NIPPON PRECISION CIRCUITS INC. Caller ID Service IC with Call Waiting OVERVIEW The SM8222A/B is a calling number identification (caller ID) and call waiting signal (dual tone signal) receiver decoder IC that conforms with the TR- NWT-000030 and SR-TSV-002476 (Bellcore) dialer telephone number display standards. It is imple- mented in CMOS and incorporates a power-down function for low power operation. FEATURES s Conforms to TR-NWT-000030 and SR-TSV- 002476 (Bellcore) standards s Call waiting s FSK demodulator s Ring signal detect circuit built-in s High input sensitivity s Input gain adjust circuit built-in s Power-down mode s Crystal oscillator circuit built-in s Single supply operation s Microcontroller I/O interface s Molybdenum-gate CMOS process s 24-pin SOP and 24-pin DIP packages s SM8222A : 2.7 to 3.3V operation s SM8222B : 4.5 to 5.5V operation APPLICATIONS s Telephones that display dialer number before and during conversation s Adapters to display dialer number before and dur- ing conversation s Answering machines s Facsimile machines s Computer peripheral devices ORDERING INFORMATION PINOUT (Top View) D e vice P a ck ag e SM8222AS 24-pin SOP SM8222AP 24-pin DIP SM8222BS 24-pin SOP SM8222BP 24-pin DIP 1 13 24 12 TIP RING GS AGND CAP RDIN RDRC VDD STGT EST STD INT CDET DR RDET MODE OSCIN OSCOUT GND DOUT DCLK FSKEN PDWN IC |
