TQ8103 recovery equivalent, 622 mb/s clock & data recovery.
* Single-chip CDR circuit for 622 Mb/s data
* Exceeds Bellcore and ITU jitter tolerance maps
* Single-ended ECL input has loopthrough path for external 50 ohm.
at 622 Mb/s. Its on-chip phase-locked loop (PLL) generates a stable 622.08 Mb/s reference based upon an external 38.88 M.
The TQ8103 CDR integrates separate detectors for acquiring frequency lock and maintaining precise phase lock. When the CDR is locked onto an incoming NRZ data stream, its phase-detect circuitry compares the phase of the incoming NRZ data and the phas.
