General Description

The Le58QL02/021/031 Quad Low Voltage Subscriber Line Audio-Processing Circuit (QLSLAC™) devices integrate the key functions of analog line cards into high-performance, veryprogrammable, four-channel codec-filter devices.

The QLSLAC devices are based on the proven design of Legerity’s reliable SLAC™ device families.

The advanced architecture of the QLSLAC devices implements four independent channels and employs digital filters to allow software control of transmission, thus providing a cost-effective solution for the audio-processing function of programmable line cards.

Key Features

  • Low-power, 3.3 V CMOS technology with 5-V tolerant digital inputs.
  • Software and coefficient compatible to the Le79Q02/ 021/031 QSLAC™ device.
  • Performs the functions of four codec/filters.
  • Software programmable:.
  • SLIC device input impedance Transhybrid balance Transmit and receive gains Equalization (frequency response) Digital I/O pins Programmable debouncing on one input Time sl.
