Enhanced E1 Single Chip Transceiver

Viewing:

Part Details

  • Complete E1(CEPT) PCV-30/ISDN-PRI transceiver
  • Long- and short-haul line eterface for clock/data recovery and waveshaping
  • 32-bit or 128-bit crystalless jitter attenuator
  • Generates line buildouts for both 120Ω and 75Ω lines
  • Frames to FAS, CAS, and CRC4 formats
  • Dual elastic buffers connect to asynchronous backplanes up to 8.192MHz
  • 8-bit parallel control port can be used directly
  • Parallel port can also be muxed or nonmuxed to bus
  • Extracts/inserts CAS signaling
  • Detects/generates remote and AIS alarms
  • Progammable output clocks for Fractional E1, H0, and H12
  • Independent transmit/receive functions
  • Full access to both Si and Sa bits aligned with CRC multiframe
  • Four testing loopbacks
  • Large error counter for bipolar and code, CRC4 code/word, FAS, and E-bits
  • Pin-compatible with DS2152 T1 Transceiver
  • Operating ranges:
    • 5V, low-power CMOS
    • 0°C to +70°C (DS2154L)
    • -40°C to +85°C (DS2154LN)
