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
