VSC6511

Deserializer/Reclocker at 1.485Gb/s

SMPTE-292M Serializer, Deserializer, and

G52311-0, Rev. 2.0

Features

General Description

The VSC6511 multi function SMPTE-292M compatible IC with Serializer, Deserializeror, or Deserializer

with reclocker modes which operate at 1.485Gb/s. As a Serializer, 20-bits of data (D19:0) are latched into the

part on the rising edge of REFCLK then scrambled and serialized out SDO0/SDO0 and/or SDO1/SDO1. An

optional CRC Generator may be enabled. As a Deserializer, serial data on SDI/SDI is recovered, de-scrambled

and deserialized onto D[19:0]. Frame alignment on SAV/EAV, line detection and frame detection outputs are

provided. As a Deserializer with reclocker, the device functions as ain the deserializer mode above and serial

data on SDI/SDI is recovered and retransmitted on SDO0/SDO0 and/or SDO1/SDO1.
