Description
The GV7600 is a serial digital video transmitter for standard
and high definition component video. With integrated
cable driving technology, the GV7600 is capable of
transmitting digital video at 270Mb/s, 1.485Gb/s and
2.97Gb/s over 75Ω coaxial cable. The device provides a
complete transmit 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 GV7600 with the complete Aviia transmitter
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, up to 1Mb/s, to be
carried over the same single, robust and cost effective
coaxial cable as the high-speed serial digital video.
The GV7600 includes a broad range of user-selectable
processing features, such as Timing Reference Signal (TRS)
insertion, illegal code word re-mapping, and ancillary data
packet insertion. The content of ancillary data packets can
be programmed 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 supports both 8-bit, 10-bit and 12-bit video data
input, for RGB or YCbCr 4:4:4, and YCbCr 4:2:2 or 4:2:0. A
configurable 20-bit wide parallel digital video input bus is
provided, with associated pixel clock and timing signal
inputs. The GV7600 supports direct interfacing of 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 accepts CEA-861 timing.
The GV7600 audio embedding function allows the carriage
of up to 8 channels of serial digital audio within the
ancillary data space of the video data stream. The input
audio 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

Input
Power pin for VCO. Connect to 1.2V DC analog followed by an RC
filter. VCO_VDD is nominally 0.7V.
Ground connection for VCO. Connect to analog GND.
GND pins for sensitive analog circuitry. Connect to analog GND.
PARALLEL DATA TIMING.
Signal levels are LVCMOS / LVTTL compatible.
861_EN = LOW:
The V signal is used to indicate the portion of the video field/frame
that is used for vertical blanking, when DETECT_TRS is set LOW.
The V signal should be set HIGH for the entire vertical blanking
period and should be set LOW for all lines outside of the vertical
blanking interval.
The V signal is ignored when DETECT_TRS = HIGH.
861_EN = HIGH:
The VSYNC signal indicates vertical timing. See 4.9.2 Ancillary Data
Blanking for timing details.
The VSYNC signal is ignored when DETECT_TRS = HIGH.
Ground connection for PLL. Connect to analog GND.
Ground connection for the serial digital cable driver. Connect to
analog GND.
Serial Data Output Signal.
Serial digital output signal operating at 2.97Gb/s, 2.97/1.001Gb/s,
1.485Gb/s, 1.485 /1.001Gb/s or 270Mb/s.
The slew rate of the output is automatically controlled according to
the setting of the RATE_SEL0 and RATE_SEL1 pins.
Power Down input.
HIGH to power down device.
CONTROL SIGNAL INPUT.
Signal levels are LVCMOS / LVTTL compatible.
Used to enable or disable the serial digital output stage.
When SDO_EN is LOW, the serial digital output signals SDO and SDO
are disabled and become high impedance.
When SDO_EN is HIGH, the serial digital output signals SDO and
SDO are enabled.
These pins are reserved and should be connected to CORE_GND.
