TMC22153AKHC

Encoders, Decoders, Converters Overview

The TMC22153AKHC is a digital video decoder IC from the TMC22x5yA family, manufactured by onsemi. It features a three-line adaptive comb filter for high-performance luminance and chrominance separation. The device supports 10-bit data processing and accepts multiple input formats including CCIR-601/624 (D1), D2, CVBS, and YC. It provides parallel and serial control interfaces and operates on a single +5V power supply with a voltage range of 4.75V to 5.25V. Packaged in a 100-MQFP (14x20) surface-mount enclosure, it is designed for studio television equipment applications.

Encoders, Decoders, Converters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment prior to installation. Check for obsolescence status as this part may be discontinued. Ensure environmental compliance documentation matches project requirements. Validate electrical specifications against system design constraints before procurement.

Encoders, Decoders, Converters Selection Notes

Select this model when broadcast-quality video processing is required within a single chip solution. Consider the 10-bit resolution and three-line comb architecture for superior artifact reduction compared to simpler bandsplit decoders. Verify compatibility with existing digital video input standards such as D1 or composite sources. Evaluate the need for specific output formats like RGB or YC during system integration planning.

Encoders, Decoders, Converters Part Context

This component belongs to the TMC22x5yA family of multistandard digital video decoders. The family includes variants with different resolutions and comb filter depths, all sharing identical register maps and physical footprints. This specific part represents the 10-bit version with three-line adaptive comb filtering capability, allowing emulation of other family members for prototyping purposes.

Encoders, Decoders, Converters Replacement Considerations

Other parts in the TMC22x5yA family are pin-compatible and software-compatible. Lower-cost versions such as the TMC22053A (8-bit, two-line comb) can substitute this unit in production after performance evaluation. Ensure that the replacement variant meets the specific resolution and filtering requirements of the final application.
