PRO-LINX ™ GS7005
Complete Serial Digital Video Receiver
FEATURES
• SMPTE 259M-C compliant
• fully integrated 270 Mb/s SDI receiver
• integrated cable equalization (100m Belden 8281 typical)
• low power consumption (750mW typical)
• operates from 0°C to 85°C
• small footprint with minimal external components
• Lock and Carrier Detect output indications
• H timing signal output
• SMPTE descrambler and NRZI decoder may be
disabled for DVB - ASI applications
• ease of design use and adjustment free operation
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.
DATA SHEET
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.
