CY7C9335

CY7C9335 SMPTE-259M/DVB-ASI Descrambler/Framer-Controller Features Fully compatible with SMPTE-259M — SMPTE-125M compliant for 4:2:2 component video — SMPTE-244M compliant for 4fsc composite video Fully compatible with DVB-ASI Operates from a single +5V or −5V supply 100-pin TQFP package Decodes 10-bit parallel digital streams for any rate from 16−40 M characters/sec (160−400 Mbits/sec serial) Operates with CY7B9334 SMPTE HOTLink™ deserializer/receiver X9 + X4 + 1 descrambler and NRZI-to-NRZ decoder may be bypassed for raw data output The inputs of the CY7C9335 are designed to be directly mated to a CY7B9334 HOTLink receiver, which converts the SMPTE-259M compatible high-speed serial data stream into 10-bit parallel characters. This device performs both TRS (sync) detection and framing, data descrambling with the SMPTE-259M X9 + X4 + 1 algorithm, and NRZI-to-NRZ decoding. These functions operate at any character rate from 16 to 40 MHz. For those systems operating with non-SMPTE-259M compliant video streams (or for diagnostic purposes), the descrambler and NRZI decoding functions can be disabled. DVB-ASI Operation The CY7C9335 also contains the necessary multiplexers, control inputs and outputs, to control a DVB-ASI compliant video stream. DVB-ASI operation is enabled through activation of a single input signal. This allows a single serial-to-parallel input port to support both SMPTE and DVB data streams under software or hardware control. In DVB-ASI mode the CY...
