Abstract :
An analog front-end LSI for 1200/2400 full-duplex modems which conform to CCITT V.22. and Bell 212A is described. The chip includes A/D and D/A converters, bandlimiting filters, delay equalizers, AGC circuit, tone generator, multipurpose low-pass filter, and voltage reference generator. The chip is fabricated by a 5-μm CMOS process, and chip size is 6.50 mm×6.37 mm. The circuit operates from +5.0-V and -5.0-V power supplies. Typical power consumption is 100 mW.
