General Description

SMPTE-259M Operation • ×9 + ×4 + 1 scrambler and NRZI encoder may be bypassed for raw data output The CY7C9235A is a CMOS integrated circuit designed to encode SMPTE-125M 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 CY7C9235A are designed to be directly mated to a CY7B9234 HOTLink transmitter, which then converts the b

Overview

CY7C9235A SMPTE-259M/DVB-ASI Scrambler/Controller.

Key Features

  • Fully compatible with SMPTE-259M.
  • Fully compatible with DVB-ASI.
  • Operates from a single +5V supply.
