LE792388TVC

                    LE792388 Next Generation Carrier Chipset (NGCC) Octal SLAC (Codec) The Le792388 Next Generation Octal Subscriber Line Audio processing Circuit (SLAC) device, in combination with the Le79271 SLIC device, implements a DSL friendly, high density eight-channel universal telephone line interface. This enables the design of a low cost, high performance, fully software programmable line interface with worldwide applicability. All AC, DC, and signaling parameters are programmable via a microprocessor interface. The Le792388 has an integrated test tool box and uses VCP test primitives and host routine capabilities to resolve faults to the line or line circuit.
