The CY7C9235A is a CMOS integrated circuit designed to encode SMPTE-125M bit-parallel digital characters (or other data formats) using the SMPTE-259M encoding rules. Following encoding, the characters are output as bit-parallel characters ready for serialization. The encoded outputs of the CY7C9235A are designed to be directly mated to a CY7B9234 HOTLink transmitter, which then converts the bit-parallel characters into a SMPTE-259M compatible high-speed serial data stream.
The CY7C9235A performs both TRS (sync) detection and filtering, data scrambling with the SMPTE-259M ×9 + ×4 + 1 algorithm, and NRZ-to-NRZI encoding. These functions of the CY7C9235A operate at a 27 MHz character rate. For those systems operating with non-SMPTE-259M compliant video streams (or for diagnostic purposes), the scrambler and NRZI encoding functions can be disabled.
