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.
