CY7C9335A-270AXC

Encoders, Decoders, Converters Overview

The CY7C9335A-270AXC is a CMOS integrated circuit designed to decode SMPTE-125M bit-parallel digital characters using SMPTE-259M decoding rules. It operates from a single +5V supply and supports both SMPTE-259M and DVB-ASI data streams. The device decodes 10-bit parallel digital streams for 27 MHz character rates, equivalent to 270 Mbits/sec serial data. It features an X9+X4+1 descrambler and NRZI-to-NRZ decoder, which can be bypassed for raw data output. The component is housed in a 100-pin TQFP package.

Encoders, Decoders, Converters Feature Summary

• Supports dual-mode operation for SMPTE-259M and DVB-ASI video streams via software or hardware control
• Performs TRS sync detection, framing, and data descrambling with the SMPTE-259M X9+X4+1 algorithm
• Includes NRZI-to-NRZ decoding functionality that can be disabled for diagnostic purposes
• Features a DVB invert controller state machine to correct inverted data streams routed through SMPTE switches

Encoders, Decoders, Converters Applications

• Decoding SMPTE-259M compatible high-speed serial data streams
• Processing DVB-ASI compliant video streams
• Diagnostic systems requiring raw data output without descrambling

Encoders, Decoders, Converters Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and operating range. Ensure compatibility with the CY7B9334 deserializer/receiver for proper system integration. Confirm voltage requirements match the single +5V supply specification before procurement.

Encoders, Decoders, Converters Selection Notes

Select this component when interfacing with SMPTE-259M or DVB-ASI sources requiring parallel output. It is suitable for applications needing simultaneous support for both standards on a single input port. Consider the 100-pin TQFP package constraints during PCB layout design.

Encoders, Decoders, Converters Part Context

This part belongs to the Cypress Semiconductor (now Infineon) family of video interface controllers. It is functionally related to the CY7B9334 SMPTE HOTLink deserializer/receiver, with which it is designed to operate directly. The device serves as a critical bridge between serial video interfaces and parallel processing systems.
