Functional Description

SMPTE-259M Operation

The CY7C9335A is a CMOS integrated circuit designed to decode SMPTE-125M 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

• 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

• X9 + X4 + 1 descrambler and NRZI-to-NRZ decoder may be bypassed for raw data output
