With integrated cable driving Supports both 720p and 1080p HD formats: technology, the GV7700 is capable of transmitting compressed Full HD: 1080p50/59.94/60fps video at 270Mb/s or 540Mb/s, or uncompressed video at HD: 1080p25/29.97/30fps 1.485Gb/s or 2.97Gb/s, over 75 coaxial cable, or HD: 720p25/29.97/30/50/59.94/60fps differentially over 100 twisted pair cable. Support for both 8/10-bit and 16/20-bit BT.1120 The GV7700 integrates the High Definition Visually Lossless compliant video interfaces, with embedded TRS or CODEC (HD-VLC) technology, which has been developed external HVF timing specifically to reduce the transmission data rate of HD 4-wire Gennum Serial Peripheral Interface (GSPI 2.0) for video over both coaxial and unshielded twisted pair (UTP) cable. This is achieved by encoding the HD video, normally external host command and control transmitted at a serial data rate of 1.485Gb/s, to the same Dedicated JTAG test interface rate as Standard Definition (SD) video, at 270Mb/s serial 1.8V core power supply and 1.8V or 3.3V digital I/O data rate. supply Small-footprint 84-pin dual-row QFN (7mm x 7mm) Low power operation, typically 180mW Wide operating temperature range: -20C to + 85C Pb-free and RoHS compliant GV7700 1 of 50 www.semtech.com Final Data Sheet Rev.8 Semtech PDS-060377 March 2016XTAL54 SEL XTAL EN XTAL XTAL XTAL OUT RBIAS AUDIO EN DIV 1001 DETECT TRS BIT20 BIT10 HDVLC EN AIN 3 4 AIN 1 2 ACLK WCLK RESET TDO TCK TMS TDI TRST SDOUT SCLK CS SDIN At 270Mb/s, the effect of cable loss is greatly reduced, The GV7700 features an audio embedding core, which 2 resulting in much longer cable transmission. For 75 supports up to 4 channels of I S serial digital audio within coaxial cable, HD-VLC allows a 1.485Gb/s HD signal to be the ancillary data space of the video data stream. The audio transmitted up to 3x the normal reach. In typical video over embedding core supports 32kHz, 44.1kHz, and 48kHz coaxial installations, when paired with Semtechs GV7704 sample rates. HD-VLC receiver, cable distances over 550m are possible. The GV7700 supports the insertion of ancillary data into the Similarly, a 2.97Gb/s 3G signal can be transmitted at horizontal blanking of the video data stream. User data can 540Mb/s using HD-VLC. be programmed via the GSPI, allowing downstream communication from the video source to sink device. The The GV7700 can also be configured to transmit HD and 3G ancillary data packing format is compliant with HDcctv 2.0 video over UTP cable, such as Cat-5e and Cat-6 cable, when communications protocol. HD-VLC encoded at 270Mb/s and 540Mb/s, respectively. Packaged in a space-saving 84-pin dual-row QFN, the The device supports both 8-bit and 10-bit per pixel YCbCr GV7700 is ideal for single PCB security cameras, where 4:2:2 BT.1120 component digital video. A configurable high-density component placement is required. Typically 20-bit or 10-bit wide parallel digital video input bus is requiring only 180mW of power, the device does not provided, with associated pixel clock and timing signal require any special heat sinking or air flow, reducing the inputs. The GV7700 supports direct interfacing of HD video over-cost of HD security camera designs. formats conforming to ITU-R BT.709 and BT.1120-6 for 1 1125-line formats, and SMPTE ST 296 for 750-line formats.
