The TQ8103 is a monolithic clock and data recovery (CDR) IC that receives
NRZ data, extracts the high-speed clock, and presents the separated data
and clock as its outputs. This device is designed specifically for SONET
OC-12 and SDH STM-4 applications 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 MHz TTL reference. The PLL is
based on a VCO constructed from integrated reactive components, which
form a low-jitter, high-Q differential tank circuit. Both frequency- and
phase-detect circuits reliably acquire and hold lock in worst-case SONET
jitter conditions and scrambling patterns. The lock-detect circuitry signals
when the CDR acquires frequency lock.
Typical SONET/SDH system applications for the TQ8103 include:
Transmission system transport cards
Switch and cross-connect line cards
ATM physical layer interfaces
Test equipment
Add/drop multiplexers
