Description
The GV7601 is a serial digital video receiver for standard
and high definition component video, operating at
270Mb/s, 1.485Gb/s and 2.97Gb/s data rates. With
integrated cable equalizer technology, the GV7601 is
capable of receiving digital video over 75Ωcoaxial cable at
lengths up to 300m for standard definition video, and up to
140m for high definition. This provides a complete receive
solution for the transmission of both interlaced and
progressive component digital video, up to 1920 x 1080, in
coaxial cable-based video systems.
Using the GV7601 with the complete Aviia™ receiver
reference design, it is possible to implement an all-digital,
bi-directional multimedia interface over coax. This
interface allows both DC power and a bi-directional,
half-duplex, auxiliary data interface to be carried over the
same single, robust and cost effective coaxial cable as the
high-speed serial digital video. The GV7601 also provides a
re-timed serial digital output for video loop-through
applications.
The GV7601 includes a broad range of user-selectable
processing features, such as Timing Reference Signal (TRS)
error detection and extraction, illegal code word
re-mapping, and ancillary data packet extraction. The
content of ancillary data packets, embedded by an Aviia
transmitter, can be extracted and retrieved via the host
interface. Device configuration and status reporting is
accomplished via the Gennum Serial Peripheral Interface
