CY7C9235A-270JXC

Specialized ICS Overview

The CY7C9235A is a CMOS digital controller designed to encode SMPTE-125M bit-parallel digital characters using SMPTE-259M encoding rules. It operates from a single +5V supply and supports both SMPTE-259M and DVB-ASI standards. The device encodes 8- and 10-bit parallel streams at a character rate of 27 MHz, corresponding to 270 Mbits/sec serial output. It features a built-in scrambler and NRZI encoder compatible with the CY7B9234 serializer. The component is housed in a 44-pin PLCC package.

Specialized ICS Feature Summary

• Fully compatible with SMPTE-259M and DVB-ASI standards
• Encodes 8- and 10-bit parallel digital streams for 27M characters/sec (270 Mbits/sec serial)
• Operates with CY7B9234 SMPTE HOTLink serializer/transmitter
• x9 + x4 + 1 scrambler and NRZI encoder may be bypassed for raw data output

Specialized ICS Applications

• SMPTE-259M video stream encoding
• DVB-ASI compliant video stream sequencing
• Digital video broadcasting systems

Specialized ICS Part Context

The CY7C9235A is part of Cypress Semiconductor's HOTLink family of high-speed serial interface components. It functions as a scrambler and controller, specifically designed to work in conjunction with the CY7B9234 serializer/transmitter to create a complete SMPTE-259M compliant transmission link.

Specialized ICS Replacement Considerations

The document history indicates that the CY7C9235A is pin-to-pin compatible with the CY7C9235.
