Clock/Data-Recovery IC Consumes Little Power

The VSC8115 is a 3.3V clock and data-recovery IC that operates at OC-12/STS-12/STM-4 (622 Mb/s) or OC3-STS-3/STM-1 (155-Mb/s) rates for terminal multiplexer, add/drop multiplexer, cross connects, wavelength-division multiplexing analog, ATM and IP systems. The chip meets ANSI, Bellcore and ITU-T specs for jitter performance and does so while consuming just 130 mW typical. The high input sensitivity of the device, coupled with its ability to retime data at the output, enables designers to maximize data coherency. Data that’s propagated over long lengths of fiber or traversed through multiple stages of a switch fabric results in signal degradation. The VSC8115 maintains data integrity by reshaping the signal using its recovered, low-jitter clock.
