Datasheet Summary
SMPTE-259M/DVB-ASI Scrambler/Controller
Features
- Fully patible with SMPTE-259M
- Fully patible 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 pliant video streams (or for diagnostic purposes), the scrambler and NRZI encoding functions can be...
