CY7B9331

The CY7B9331 HOTLink OLC Receiver is a point-to-point communications building block that receives data over high-speed serial links (fiber, coax, and twisted pair) at 160 to 330 Mbits/second. The HOTLink OLC Receiver system interface of CY7B9331 has been tailored to match OLC (Optical Link Card) timing and functionality.

The HOTLink CY7B9331 receiver accepts the serial bit stream at its differential line receiver inputs and, using a completely integrated PLL clock synchronizer, recovers the timing information necessary for data reconstruction.

The bit stream of CY7B9331 is deserialized, decoded, and checked for transmission errors. The recovered byte is presented in parallel to the receiving host along with a byte rate clock. The 8B/10B encoder/decoder can be disabled in systems that already encode or scramble the transmitted data. A Built-In Self-Test pattern generator and checker of CY7B9331 allows testing of the transmitter, receiver, and the connecting link as a part of a system diagnostic check.

The CY7B9331 HOTLink Receiver is a companion part to the CY7B923 HOTLink Transmitter. The HOTLink chip set provides a complete physical interface solution. For further information on HOTLink Transceiver and Receiver functions see the CY7B923/933 datasheet.
