Description
Triple-Rate (SD/HD/3G) SDI Transmitter with VC-2 Encoder and Audio Decoder
TW6872
The TW6872 is a triple-rate (SD/HD/3G) SDI transmitter. It receives parallel BT.656/BT.1120/ASI video data from a CMOS sensor/ISP chip. It also receives analog audio, or serial digital audio. The TW6872 serializes the video and audio into an SDI stream and transmits it to an SDI receiver via its integrated cable driver.
In addition to the standard SDI format with uncompressed raw video data, TW6872 can optionally compress video with a visually lossless VC-2 compression algorithm to send the video formats normally running at HD rate (1.5Gbps) on the cable at SD rate (270Mbps), and therefore achieve longer cable reach.
Together, the TW6872 and Intersil’s TW6874 SDI receiver provide a complete end-to-end SDI link solution and can operate with or without VC-2 compression. Integrated audio/video test patterns and PRBS checker ease system design and implementation.
The TW6872 is available in a 76 Ld QFN. It ...
