Am79C02/03/031(A) Dual Subscriber Line Audio Processing Circuit (DSLAC™) Devices DISTINCTIVE CHARACTERISTICS GENERAL DESCRIPTION I Software programmable: The Am79C02/03/031(A) Dual Subscriber Line Audio Processing Circuit (DSLAC device) integrates the key functions of an analog linecard into a single high-performance, programmable dual codec/filter device. The DSLAC device is based on the proven design of the reliable Am7901A Subscriber Line Audio Processing Circuit (SLAC ™ device). The advanced architecture of the DSLAC device implements two independent channels and employs digital filters to allow software control of transmission, thus providing a cost effective solution for the analog to PCM function of a linecard. — SLIC impedance — Transhybrid balance — Transmit and receive gains — Equalization — Digital I/O pins — Time Slot Assigner — PCM transmit clock edge options I Adaptive transhybrid balance filter (A suffix only) I A-law or µ-law coding I Dual PCM ports — Up to 8.192 MHz each (128 channels per port) I 2.048 MHz or 4.096 MHz master clock I Direct transformer drive The Am79C02/03/031(A) DSLAC device’s advanced CMOS technology makes this an economical device that has both the functionality and the low power consumption needed in linecard designs to maximize linecard density at minimum cost. When used with two Legerity SLICs, the DSLAC device provides software configurable solutions to the BORSCHT function. I Built-in test modes I Low power CMOS I Mixed mode (analog and digital) impedance scaling I Performance characteristics guaranteed over 12 dB gain range Although the name and logo have changed, the data contained herein remains the same as the most recent AMD revision of this document.
