DESCRIPTION
The N681386/87, implements a single channel FXS telephone line interface optimized for short loop applications. It integrates SLCC (Subscriber Line Control Circuit) functionality with a programmable CODEC and a DC/DC controller. The SLCC supports internal ringing up to 90 VPK (5 REN at 4k ft) ideal for Customer Premise Equipment (CPE). The CODEC can be configured for μ-law, A-law or 16-bit linear PCM encoding. It also supports a comprehensive set of signaling capabilities required to supervise and control the telephone lines. These include tone generation, ring tones, DTMF detection/ generation as well as FSK generation. An on-chip Pulse Width Modulation (PWM) driver allows control of an inductor based DC/DC converter. Programmable impedance and trans-hybrid balancing allow for worldwide deployment.
