Zarlink?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)

Features & Benefits

• 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, 0-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 Zarlink SLIC devices with switching regulator
• Maximum channel bandwidth for V.90 modems
