Quad Multi-Rate CDR (65 Mbps - 3.2 Gbps)

The CX20501 is a quad Clock and Data Recovery (CDR) circuit designed for +3.3 or +2.5 V low power operation. As a multi-rate device, it CAN support data rates from 65 Mbps to 3.2 Gbps. Because each CDR operates independently, each CAN lock to a common frequency or to a separate frequency to support diverse applications without an external frequency reference. A quasi-limiting Amplifier is used to improve the input sensitivity of the device. To save power, the individual output Clocks and/or CDRs CAN be powered down and the output drive level is also selectable. The high-speed I/O is differential Positive Current Mode Logic (PCML) with an on-chip 50 to Vdd (single-ended) input termination/output backmatch. The I/O CAN be used either differentially or single-ended. A serial Interface (+3.3 V/+2.5 V CMOS) is used to fine-tune the frequency acquisition characteristics and the operating bit-rate. Alarms are provided for both Loss Of Lock (LOL) and Loss Of Signal (LOS), and a CDR bypass feature allows direct connection of the input data to the output Buffer without re-timing. The CX20501 I/O pin configuration is a drop-in replacement for the OC-48 CX20464 single-rate quad CDR and complements all of Mindspeeds Crosspoint Switches Figure 1 illustrates the quad CDR IC functional block diagram and Table 1 through Table 9 list the CX20501 electrical specifications.
