SMPTE-259M/DVB-ASI Scrambler/Controller

CY7C9235A SMPTE-259M/DVB-ASI Scrambler/Controller Features • Fully compatible with SMPTE-259M • Fully compatible with DVB-ASI • Operates from a single +5V supply • 44-pin PLCC package • Encodes both 8- and 10-bit parallel digital streams for 27M characters/sec (270 Mbits/sec serial) • Operates with CY7B9234 SMPTE HOTLink serializer/transmitter This device performs both TRS (sync) detection and filtering, data scrambling with the SMPTE-259M ×9 + ×4 + 1 algorithm, and NRZ-to-NRZI encoding. These functions 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. DVB-ASI Operation The CY7C9235A also contains the necessary multiplexers, control inputs, and outputs, to sequence out a DVB-ASI compliant video stream. DVB-ASI operation is enabled through activation of a single input signal. This allows a single serial output port to support both SMPTE and DVB data streams under software or hardware control. In DVB-ASI mode the CY7C9235A operates with two enable signals (ENA and ENN) to allow data to be presented from either synchronous (clocked) or asynchronous FIFOs. When data is not available, the CY7C9235A ensures that the proper fill character (K28.5) is generated by the attached CY7B9234 serializer. The CY7C9235A operates from a single +5V supply. It is available in a 44-pin PLCC space saving package. www.DataSheet4U.com Functional Descrip.
