General Description

The VSC6424 is a 500Mb/s video shift register IC that is based on a 40-bit user-configured shift register.

The shift register may be used either as a multiplexer (parallel in, serial out) or as a demultiplexer (serial in, par-

allel out). The VSC6424 can be configured into 8 5-bit, 8 4-bit, 5 8-bit, 4 10-bit, 2 16-bit, 2 20-bit, 1 32-bit, or 1

40-bit shift register.
