With integrated high performance cable equalizer technology, the GV7704 is capable of receiving HD video at 270Mb/s and 1.485Gb/s over 75Ω coaxial cable, or differentially over a 100Ω twisted pair cable. • Four 8/10-bit BT.1120 compliant output video interfaces, with embedded TRS and external HVF timing outputs • Automatic independent detection of HD-SDI and HD-VLC video input data streams per channel • Downstream ancillary data detection and extraction • Automatic HDcctv Stream ID detection • 4-wire Gennum Serial Peripheral Interface (GSPI 2.0) for external host command and control • JTAG test interface • 1.2V core voltage power supplies • 1.8V digital I/O power supply • Small footprint 169-BGA (11mm x 11mm) • Low power operation, typically 814mW • Wide operating temperature range: -20°C to + 85°C • Pb-free and RoHS compliant GV7704 Product Brief PDS-060903 The GV7704 integrates the High Definition Visually Lossless CODEC (HD-VLC™) technology, which has been developed specifically to reduce the transmission data rate of HD video over both coaxial and unshielded twisted pair (UTP) cable. This is achieved by encoding the HD video, normally transmitted at a serial data rate of 1.485Gb/s, to the same rate as Standard Definition (SD) video, at 270Mb/s serial data rate. At 270Mb/s, the effect of cable loss is greatly reduced, resulting in much longer cable transmission. For 75Ω coaxial cable, cable reach can be extended up to 3x the normal reach when transmitting encoded HD at 270Mb/s. In typical video over coaxial installations, cable distances of up to 550m are possible. www.semtech.com Rev.2 July 2015 1 of 3 Semtech formatted in compliance with the HDcctv 2.0 communications protocol. The GV7704 can also be configured to receive HD video over UTP cable, such as Cat-5e and Cat-6 cable, when HD-VLC encoded at 270Mb/s. The GV7704 features an audio de-embedding core, which provides the extraction of up to 4 channels of I2S serial digital audio from the ancillary data space of the input video data stream. The audio de-embedding core supports 32kHz, 44.1kHz, and 48kHz sample rates. The device supports the reception of both 8-bit and 10-bit per pixel YCbCr 4:2:2 BT.1120 component digital video. A single 10-bit wide parallel digital video output bus per channel is provided, with associated pixel clock and timing signal outputs. The GV7704 supports direct interfacing of HD video formats conforming to ITU-R BT.709 and BT.1120-6 for 1125-line formats, and SMPTE ST 296 for 750-line formats. Packaged in a space saving 169 ball 11 x 11mm BGA, the GV7704 is ideal for high density, multi-channel video recorder architectures. Typically requiring only 814mW of power, the device does not require any special heat sinking or air flow, reducing the over cost of HD DVR designs. The GV7704 supports the extraction of ancillary data from the horizontal blanking of the input video data stream. Ancillary data packets can be accessed via the GSPI, allowing downstream communication from the video source to sink device. The GV7704 recognizes data packets *Frame structure with encoded HD only. Does not support SD/D1 video.s Functional Block Diagram TDO TCK TMS TDI TRST RESET SDOUT SCLK CS SDIN RBIAS Common GSPI JTAG Digital Control Channel 3 CH3_SDI CH3_SDI EQ CH3_SDO CH3_SDO CDR S2P Format Detect Audio/ Ancilliary Extraction HDVLC Decoder Output Format Channel 2 CH2_SDI CH2_SDI EQ CH3_PCLK CH3_DOUT[9:0] CH3_AOUT_1_2 CH3_AOUT_3_4 CH3_ACLK CH3_WCLK CH2_SDO CH2_SDO CDR S2P Format Detect Audio/ Ancilliary Extraction HDVLC Decoder Output Format Channel 1 CH2_PCLK CH2_DOUT[9:0] CH2_AOUT_1_2 CH2_AOUT_3_4 CH2_ACLK CH2_WCLK CH1_SDO CH1_SDO CH1_SDI CH1_SDI EQ CDR S2P Format Detect Audio/ Ancilliary Extraction HDVLC Decoder Output Format CH0_SDO CH0_SDO Channel 0 CH0_SDI CH0_SDI EQ CH1_PCLK CH1_DOUT[9:0] CH1_AOUT_1_2 CH1_AOUT_3_4 CH1_ACLK CH1_WCLK CDR S2P Format Detect Audio/ Ancilliary Extraction HDVLC Decoder Output Format CH0_PCLK CH0_DOUT[9:0] CH0_AOUT_1_2 CH0_AOUT_3_4 CH0_ACLK CH0_WCLK GV7704 Functional Block Diagram GV7704 Product Brief PDS-060903 www.semtech.com Rev.2 July 2015 2 of 3 Semtech IMPORTANT NOTICE Information relating to this product and the application or design described herein is believed to be reliable, however such information is provided as a guide only and Semtech assumes no liability for any errors in this document, or for the application or design described herein.
