Quad (SD/HD) SDI Receiver with Adaptive Equalizer, VC-2 Decoder and Audio CODEC
independent channels, each consisting of an adaptive
equalizer, clock data recovery, audio decoder and VC-2
decompression engine. Each channel receives high speed
serial data over extended coaxial cable lengths and deserialize
the data into video/audio streams for the back-end device.
The video streams are output as: 8-bit BT.656 for SD; BT.1120
in 8/16 bit mode for HD. The audio streams are output
through an I2S audio digital interface in a multichannel
interleaving format. In addition to the extraction of embedded
SDI audio, the TW6874 incorporates a 5-channel audio ADC
decoder to decode analog audio inputs and output them
through the same I2S interface.
A visually lossless VC-2 (Dirac) compression/decompression
engine is implemented in the TW6872/TW6874 SDI Tx/Rx
pair to extend the reach of HD-SDI to that of SD-SDI. An
interrupt pin can be used to signal the host processor of
ancillary data packet detection. Finally, integrated audio test
patterns and PRBS checker ease system design and
implementation.
