Device Overview

Summary

Microchip's cost-effective, software-programmable solution is the Le58QL02/021/031 QLSLAC and the Le58QL061/063 QLSLAC line of DSP-based voice codec/filters. The four-channel QLSLAC devices handle the analog-to-digital and digital-to-analog conversion, filtering, compression and expansion functions required to interface a telephone's analog voice signals to the digital PCM highway or General Circuit Interface (GCI).

Additional Features
  • Low-power, 3.3 V CMOS technology with 5 V tolerant digital inputs
  • Pin programmable PCM/MPI or GCI interface
  • Software and coefficient compatible to the Le79Q061/ 063 QSLAC device
  • Standard PCM/microprocessor interface (PCM/MPI mode)
    • Single or Dual PCM ports available
    • Time slot assigner (up to 128 channels per port)
    • Clock slot and transmit clock edge options
    • Optional supervision on the PCM highway
    • 1.536, 1.544, 2.048, 3.072, 3.088, 4.096, 6.144, 6.176, or 8.192 MHz master clock derived from MCLK or PCLK
    • 0P access to PCM data
    • Real Time Data with interrupt (open drain or TTL)
    • Broadcast mode
  • General Circuit Interface (GCI mode)
    • Control and PCM data on a single port
    • 2.048 Mbits/s data rate
    • 2.048 MHz or 4.096 MHz clock option
  • Performs the functions of four codec/filters
  • Software programmable
    • SLIC device input impedance and Transhybrid balance
    • Transmit and receive gains and Equalization
    • Programmable Digital I/O pins with debouncing
  • A-law, µ-law, or linear coding
  • Built-in test modes with loopback, tone generation, and 0P access to PCM data
  • Mixed state (analog and digital) impedance scaling
  • Performance guaranteed over a 12 dB gain range
  • Supports multiplexed SLIC device outputs
  • 256 kHz or 293 kHz chopper clock for SLIC devices with switching regulator
  • Maximum channel bandwidth for V.90 modems
