PHY 4-CH 256-Pin BGA

The CYV15G0403DXB Independent Clock Quad HOTLink II 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 like optical fiber, balanced, and unbalanced copper transmission lines. 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 CYV15G0403DXB satisfies the SMPTE-259M and SMPTE-292M compliance as per SMPTE EG34-1999 Pathological Test Requirements. As a second-generation HOTLink device, the CYV15G0403DXB extends the HOTLink family with enhanced levels of integration and faster data rates, while maintaining serial-link compatibility (data, command, and BIST) with other HOTLink devices. The transmit (TX) section of the CYV15G0403DXB Quad HOTLink II consists of four independent byte-wide channels. Each channel can accept either 8-bit data characters or preencoded 10-bit transmission characters. Data characters may be passed from the Transmit Input Register to an integrated 8B/10B Encoder to improve their serial transmission characteristics. These encoded characters are then serialized and output from dual Positive ECL (PECL) compatible differential transmission-line drivers at a bit-rate of either 10 or 20 times the input reference clock for that channel.
