These encoded characters are then serialized, converted to NRZI, and output from two PECL-compatible differential transmission line drivers at a bit-rate of either 10 or 20 times the input reference clock in 8-bit (or 10-bit bypass) mode, or 12 or 24 times the reference clock in 10-bit (or 12-bit bypass) mode. The receive section of the CY7C9689 HOTLink accepts a serial bit-stream from one of two PECL compatible differential line receivers and, using a completely integrated PLL Clock Synchronizer, recovers the timing information necessary for data reconstruction. The recovered bit stream is converted from NRZI to NRZ, deserialized, framed into characters, 4B/5B or 5B/6B decoded, and checked for transmission errors. The recovered 8- or 10-bit decoded...
