Abstract :
An analog front end LSI for 9600/4800-b/s modems has been developed. To reduce total error rate, group delay time equalizers (GDT-EQLs) for bandlimiting filters are integrated on the chip. Noise level is suppressed to -77 dBm without the GDT-EQL. Relative GDT characteristics of Tx and Rx filters are less than 80 μs in the frequency range from 800 Hz to 3.0 kHz
