LE58QL031DJCT Description

Short technical summary and product information.

The LE58QL031DJCT from Microchip Technology is a Quad Low Voltage Subscriber Line Audio-Processing Circuit (QLSLAC) based on the VE580 series. This highly programmable, four-channel codec-filter device integrates key functions of analog line cards, offering a cost-effective solution for audio processing in programmable line cards.

 

Designed with 3.3V CMOS technology and 5V tolerant digital inputs, the LE58QL031DJCT performs codec and filter functions for four independent channels. It supports A-law, µ-law, or linear coding and features a standard microprocessor interface with single or dual PCM ports. The device operates over a temperature range of -40°C to 85°C and is housed in a 32-PLCC (J-Lead) package suitable for surface mounting.

 

Key features include software programmability for SLIC input impedance, transhybrid balance, transmit and receive gains, and equalization. It supports various master clock frequencies from 1.536 MHz to 8.192 MHz and includes built-in test modes. This device is software and coefficient compatible with the Le79Q02/021/031 QSLAC™ devices.
