IDT82V2081
FEATURES:
• Single channel T1/E1/J1 long haul/short haul line interfaces • Supports HPS (Hitless Protection Switching) for 1+1 protection
without external relays
- Active edge of transmit clock (TCLK) and receive clock (RCLK) - Active level of transmit data (TDATA) and receive data (RDATA) - Receiver or transmitter power down
• Receiver sensitivity exceeds -36 dB@772KHz and -43 dB@1024
- High impedance setting for line drivers
KHz - PRBS (Pseudo Random Bit Sequence) generation and detection
• Programmable T1/E1/J1 switchability allowing one bill of ma-
with 215-1 PRBS polynomials for E1
terial for any line condition
- QRSS (Quasi Random Sequence Signals) generation and detection
