The W681388DG TR from Quarktwin Technology Ltd. is a single programmable extended CODEC/SLIC designed for short loop applications. It integrates SLIC functionality with a programmable CODEC and a DC-to-DC controller, supporting internal ringing up to 90 V_{PK} for customer premise equipment. The CODEC can be configured for Oº-law/A-law or 16-bit linear PCM encoding and includes extensive signaling capabilities such as tone generation, DTMF generation and detection, FSK generation, and metering pulse generation. This device performs complete BORSCHT functions for a single channel and features programmable linefeed characteristics, including ringing frequency and amplitude. It operates at 3.3V and is available in compact LQFP-48 and QFN-48 packages. The W681388 also supports loop test and diagnostics, making it suitable for applications such as Analog Telephone Adapters, VoIP gateways, and optical network terminals. Its high integration reduces system BOM and footprint while maintaining low power consumption, making it ideal for battery-sensitive applications.
