Overview
CY7C9335A SMPTE-259M/DVB-ASI Descrambler/Framer-Controller Features • Fully compatible with SMPTE-259M • Fully compatible with DVB-ASI • Operates from a single +5V supply • 100-pin TQFP package • Decodes 10-bit parallel digital streams for 27M characters/sec (270 Mbits/sec serial) • Operates with CY7B9334 SMPTE HOTLink deserializer/receiver The inputs of the CY7C9335A 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 a 27 MHz character rate.
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 CY7C9335A also contains the necessary multiplexers, control inputs and output...
