With integrated cable driving technology, the GV7700 is capable of transmitting HD video at a compressed 270Mb/s or an uncompressed1.485Gb/s over 75Ω coaxial cable, or differentially over 100Ω twisted pair cable. The GV7700 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. www.semtech.com Rev.2 July 2015 HD at 270Mb/s RS422 1080p 25/29.97/30fps GV7700 Product Brief GENDOC-057176 GV7700 Transmitter 1 of 3 Semtech At 270Mb/s, the effect of cable loss is greatly reduced, resulting in much longer cable transmission. For 75Ω coaxial cable, HD-VLC allows a 1.485Gb/s HD signal to be transmitted up to 3x the normal reach. In typical video over coaxial installations, when paired with Semtech’s GV7704 HD-VLC receiver, cable distances of up to 550m are possible. The GV7700 features an audio embedding core, which supports up to 4 channels of I2S serial digital audio within the ancillary data space of the video data stream. The audio embedding core supports 32kHz, 44.1kHz and 48kHz sample rates. The GV7700 supports the insertion of ancillary data into the horizontal blanking of the video data stream. User data can be programmed via the GSPI, allowing downstream communication from the video source to sink device. The ancillary data packing format is compliant with HDcctv 2.0 communications protocol. The GV7700 can also be configured to transmit HD video over UTP cable, such as Cat-5e and Cat-6 cable, when HD-VLC encoded at 270Mb/s. The device supports both 8-bit and 10-bit per pixel YCbCr 4:2:2 BT.1120 component digital video. A configurable 20-bit or 10-bit wide parallel digital video input bus is provided, with associated pixel clock and timing signal inputs. The GV7700 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 84-pin dual-row QFN, the GV7700 is ideal for single PCB security cameras, where high-density component placement is required. Typically requiring only 180mW of power, the device does not require any special heat sinking or air flow, reducing the over-cost of HD security camera designs. 1Frame structure with encoded HD only. Does not support SD/D1 video.
