Description

The VSC8122 is a single-chip clock recovery IC for use in SONET OC-48, OC-24, OC-12, OC-3, or Giga- bit Ethernet systems operating at their respective 2.48832Gb/s, 1.24416Gb/s, 622.08Mbps, 155.52Mbps, or 1.25Gbps data rates. The VSC8122 complies with SONET jitter tolerance, jitter transfer and jitter generation specifications.

Alarm functions support typical telecom system applications. The Loss of Lock (LOL) output indicates when the device goes out of lock, which would most often occur in the event of a loss of valid data. The NOREF output flags when the reference input to the VSC8122 either is removed, or goes severely out of tolerance.
