N681386DG Description

Short technical summary and product information.

The Nuvoton N681386DG is a single-channel FXS telephone line interface IC optimized for short loop applications. It integrates Subscriber Line Control Circuit (SLCC) functionality with a programmable CODEC and a DC/DC controller. The SLCC supports internal ringing up to 90 V PK and 5 REN at 4k ft, making it ideal for Customer Premise Equipment (CPE).

 

The CODEC can be configured for μ-law, A-law, or 16-bit linear PCM encoding. It supports comprehensive signaling capabilities including tone generation, ring tones, DTMF detection/generation, and FSK generation. An on-chip Pulse Width Modulation (PWM) driver controls an inductor-based DC/DC converter. Programmable impedance and trans-hybrid balancing allow for worldwide deployment.

 

This device operates at 3.3V and features a 48-LQFP package suitable for surface mounting. The operating temperature range is -40°C to 85°C. It supports digital interfaces like PCM (G.711 μ-Law, A-Law, 16-bit linear), GCI, and SPI bus, with both PCM Master and Slave modes supported. The part also includes loop test and diagnostics support, such as integrated loopback modes and real-time linefeed monitoring.
