APPLICATIONS

Limited space, low power SMPTE 259M-C or generic

270Mb/s serial to parallel interfaces; DVB-ASI 270Mb/s

receive interface; broadcast quality uncompressed video

interface for industrial and professional video equipment

such as video editing workstations.

DESCRIPTION

The GS7005 is a BiCMOS integrated circuit capable of

operating as a complete 270Mb/s Serial Digital Video

receiver. The GS7005 provides a complete serial digital

video receive solution while consuming only 750mW.

The serial data input accepts SMPTE 259M-C compliant

signals. An on-chip by-passable equalizer typically pro-

vides 100m of co-axial cable equalization. The clock

recovery is performed on chip with minimal external

components. The incoming serial data is decoded using an

NRZI decoder and SMPTE descrambler to provide SMPTE

125M compliant 27Mb/s parallel data outputs and clock.
