The CYV15G0404DXB Independent Clock Quad HOTLink IITM Transceiver is a point-to-point or point-to-multipoint communications building block enabling transfer of data over a variety of high-speed serial links including SMPTE 292, SMPTE 259 and DVB-ASI video applications. The signaling rate can be anywhere in the range of 195 to 1500 MBaud per serial link. Each channel operates independently with its own reference clock allowing different rates. Each transmit channel accepts parallel characters in an Input Register, encodes each character for transport, and then converts it to serial data. Each receive channel accepts serial data and converts it to parallel data, decodes the data into characters, and presents these characters to an Output Register. The received serial data can also be reclocked and retransmitted through the serial outputs. Figure 1 illustrates typical connections between independent video co-processors and corresponding CYV15G0404DXB chips.
