Functional Description

SMPTE-259M Operation

The CY7C9235 is a CMOS integrated circuit designed to encode SMPTE-125M and SMPTE-244M bit-parallel digital characters (or other data formats) using the SMPTE-259M encoding rules. Following encoding, the characters are output as bit-parallel characters ready for serialization. The encoded outputs of the CY7C9235 are designed to be directly mated to a CY7B9234 HOTLink transmitter, which then converts the bit-parallel characters into a SMPTE-259M compatible high-speed serial data stream.

特性 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

• 44-pin PLCC package

• Encodes both 8- and 10-bit parallel digital streams for any rate from 16–40 M characters/sec (160–400 Mbits/sec serial)

• Operates with CY7B9234 SMPTE HOTLink™ serializer/transmitter

• X9 + X4 + 1 scrambler and NRZI encoder may be bypassed for raw data output
