Functional Description
SMPTE-259M Operation
The CY7C9335 is a CMOS integrated circuit designed to decode SMPTE-125M and SMPTE-244M bit-parallel digital characters (or other data formats) using the SMPTE-259M decoding rules. Following decoding, the characters are framed by locating the 30-bit TRS pattern in the parallel character stream. The framed characters are then output.
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
