Description：

The GV7600 is a serial digital video transmitter for standardand high definition component video. With integratedcable driving technology, the GV7600 is capable oftransmitting digital video at 270Mb/s, 1.485Gb/s and2.97Gb/s over 75Ω coaxial cable. The device provides acomplete transmit solution for the transmission of bothinterlaced and progressive component digital video, up to1920 x 1080, in coaxial cable-based video systems.Using the GV7600 with the complete Aviia transmitterreference design, it is possible to implement an all-digital,bi-directional multimedia interface over coax. Thisinterface allows both DC power and a bi-directional,half-duplex, auxiliary data interface, up to 1Mb/s, to becarried over the same single, robust and cost effectivecoaxial cable as the high-speed serial digital video.The GV7600 includes a broad range of user-selectableprocessing features, such as Timing Reference Signal (TRS)insertion, illegal code word re-mapping, and ancillary datapacket insertion. The content of ancillary data packets canbe programmed via the host interface. Deviceconfiguration and status reporting is accomplished via theGennum Serial Peripheral Interface (GSPI). Alternatively,many processing features and operational modes can beconfigured directly through external pin settings.The device supports both 8-bit, 10-bit and 12-bit video datainput, for RGB or YCbCr 4:4:4, and YCbCr 4:2:2 or 4:2:0. Aconfigurable 20-bit wide parallel digital video input bus isprovided, with associated pixel clock and timing signalinputs. The GV7600 supports direct interfacing of ITU-RBT.656 SD formats, and HD formats conforming to ITU-RBT.709 and BT.1120-6 for 1125-line formats, and SMPTE296M for 750-line formats. The device may also beconfigured to accepts CEA-861 timing.The GV7600 audio embedding function allows the carriageof up to 8 channels of serial digital audio within theancillary data space of the video data stream. The inputaudio signal formats supported by the device includeAES/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 and48kHz synchronous or asynchronous for HD formats.Additional audio processing features include: individualchannel enabling, audio group selection, groupreplacement, channel swapping and audio channel statusinsertion.The GV7600 supports an Asynchronous Serial Interface(ASI), to carry compressed audio and video transportstreams, conforming to IEC 13818-1, at 270Mb/s. Transportstream data is input to the device at a synchronous 27MHz clock rate. The device will automatically 8b/10b encode thedata, prior to serialization.Packaged in a space saving 100-BGA, the GV7600 is ideal fordesigns where high-density component placement isrequired. Typically requiring only 400mW power, the devicecan be used as a high bandwidth alternative to analogcomposite or component video interfaces, providing a highquality, all-digital, long reach video transmit solution.
