IDT82P2821规格书详情
Integrates 21+1 channels T1/E1/J1 short haul line interface
units for 100 Ω T1, 120 Ω E1, 110 Ω J1 twisted pair cable and
75 Ω E1 coaxial cable applications
Per-channel configurable Line Interface options
• Supports various line interface options
– Differential and Single Ended line interfaces
– true Single Ended termination on primary and secondary side of transformer
for E1 75 Ω coaxial cable applications
– transformer-less for Differential interfaces
• Fully integrated and software selectable receive and transmit
termination
– Option 1: Fully Internal Impedance Matching with integrated receive
termination resistor
– Option 2: Partially Internal Impedance Matching with common external
resistor for improved device power dissipation
– Option 3: External impedance Matching termination
• Supports global configuration and per-channel configuration to
T1, E1 or J1 mode
Per-channel programmable features
• Provides T1/E1/J1 short haul waveform templates and userprogrammable
arbitrary waveform templates
• Provides two JAs (Jitter Attenuator) for each channel of receiver
and transmitter
• Supports AMI/B8ZS (for T1/J1) and AMI/HDB3 (for E1) encoding
and decoding
Per-channel System Interface options
• Supports Single Rail, Dual Rail with clock or without clock and
sliced system interface
• Integrated Clock Recovery for the transmit interface to recover
transmit clock from system transmit data
Per-channel system and diagnostic functions
• Provides transmit driver over-current detection and protection
with optional automatic high impedance of transmit interface
• Detects and generates PRBS (Pseudo Random Bit Sequence),
ARB (Arbitrary Pattern) and IB (Inband Loopback) in either
receive or transmit direction
• Provides defect and alarm detection in both receive and transmit
directions.
– Defects include BPV (Bipolar Violation) /CV (Code Violation) and EXZ
(Excessive Zeroes)
– Alarms include LLOS (Line LOS), SLOS (System LOS), TLOS
(Transmit LOS) and AIS (Alarm Indication Signal)
• Programmable LLOS detection /clear levels. Compliant with ITU
and ANSI specifications
• Various pattern, defect and alarm reporting options
– Serial hardware LLOS reporting (LLOS, LLOS0) for all 22 channels
– Configurable per-channel hardware reporting with RMF/TMF
(Receive /Transmit Multiplex Function)
– Register access to individual registers or 16-bit error counters
