CY7C9335A-270AXCT

Encoders, Decoders, Converters Overview

The CY7C9335A-270AXCT is a CMOS integrated circuit designed to decode SMPTE-125M bit-parallel digital characters or other data formats using SMPTE-259M decoding rules. It operates from a single +5V supply and supports both SMPTE-259M and DVB-ASI environments. The device decodes 10-bit parallel digital streams for 27M characters per second, equivalent to 270 Mbits/sec serial data. It performs TRS detection, framing, descrambling with the X^9+X^4+1 algorithm, and NRZI-to-NRZ decoding. Available in a 100-pin TQFP package, it interfaces directly with the CY7B9334 deserializer/receiver.

Encoders, Decoders, Converters Feature Summary

• Supports dual-mode operation for SMPTE-259M and DVB-ASI video streams via software or hardware control.
• Integrates SMPTE descrambler, NRZI-to-NRZ decoder, and TRS framer for character boundary alignment.
• Includes DVB invert controller state machine to correct inverted data streams routed through SMPTE switches.
• Allows bypass of descrambler and NRZI functions for raw data output or diagnostic purposes.

Encoders, Decoders, Converters Applications

• Decoding SMPTE-259M compatible high-speed serial video data streams.
• Processing DVB-ASI compliant video streams requiring error detection and command code reception.
• Systems utilizing CY7B9334 HOTLink deserializer/receiver for serial-to-parallel conversion.

Encoders, Decoders, Converters Procurement Notes

Verify the specific ordering suffix 'CT' corresponds to the tape and reel packaging variant as documented in the official Infineon/Cypress ordering information. Confirm that the commercial operating temperature range (0°C to +70°C) meets system requirements. Ensure compatibility with the single +5V supply voltage specification before procurement.

Encoders, Decoders, Converters Selection Notes

Select this component when interfacing with SMPTE-259M or DVB-ASI standards requiring integrated descrambling and framing. It is suitable for designs needing direct connection to the CY7B9334 deserializer. Consider the 100-pin TQFP package constraints and the requirement for a single +5V power supply during system architecture planning.

Encoders, Decoders, Converters Part Context

This device belongs to the Cypress Semiconductor SMPTE/DVB decoder family, specifically designed to work in conjunction with the CY7B9334 HOTLink receiver. It serves as a critical interface component for converting serialized video data into framed parallel characters for downstream processing in broadcast and professional video equipment.

Encoders, Decoders, Converters Replacement Considerations

The datasheet notes pin-to-pin compatibility with the CY7C9335. Verify if the CY7C9335A-270AXC (non-tape and reel version) is an acceptable alternative based on packaging requirements. No other cross-model replacements are explicitly confirmed in the provided documentation.
