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 75Ω coaxial cable at
lengths up to 460m for standard definition video, and up to
230m 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
(GSPI). Alternatively, many processing features and

operational modes can be configured directly through
external pin settings.
The device can output both 8-bit, 10-bit and 12-bit video
data, for RGB or YCbCr 4:4:4, and YCbCr 4:2:2 or 4:2:0. A
configurable 20-bit wide parallel digital video output bus is
provided, with associated pixel clock and timing signal
outputs. The GV7601 supports ITU-R BT.656 SD formats,
and HD formats conforming to ITU-R BT.709 and BT.1120-6
for 1125-line formats, and SMPTE 296M for 750-line
formats. The device may also be configured to output
CEA-861 timing.
The GV7601 audio de-embedding function allows the up to
8 channels of serial digital audio within the ancillary data
space of the video data stream to be extracted. The audio
output signal formats supported by the device include
AES/EBU for professional applications, S/PDIF, and I2S.
16-bit, 20-bit and 24-bit audio formats are supported at
48kHz synchronous-to-video for SD video formats and
48kHz synchronous or asynchronous for HD formats.
Additional audio processing features include: individual
channel extraction, audio group selection, group
replacement, channel swapping and audio channel status
extraction.
The GV7601 also supports an Asynchronous Serial
Interface (ASI) 270Mb/s input, carrying compressed audio
and video transport streams, conforming to IEC 13818-1.
Transport stream data is output from the device at a
synchronous 27MHz clock rate. The device will
automatically deserialize and 8b/10b decode the data.
Packaged in a space saving 100-BGA, the GV7601 is ideal
for designs where high-density component placement is
required. Typically requiring only 570mW power, the
device can be used as a high bandwidth alternative to
analog composite or component video interfaces, providing
a high quality, all-digital, long reach video receive solution.
