The CX02551 is a receiver IC consisting of a Variable Gain Amplifier (VGA), limiting amplifier, CDR, and a 1:16 deserializer. The multirate CDR maximizes jitter tolerance, minimizes pattern-dependant jitter, and does not require an external frequency reference. By default, upon reset, the CX02551 registers are set to operate at the SONET OC-48 specification. However, through the serial programming interface, the receiver can be customized to operate with data rates from 155 Mbps to 3.2 Gbps. |
