TMC2272AKEC3 - 36-Bit 50 MHz Color Converter | onsemi
MPN: TMC2272AKEC3 ✗ End of LifeTMC2272AKEC3 Overview
A digital color-space converter is a signal-processing IC that converts color values between coordinate systems such as RGB, YUV, YCbCr, or related representations. Within the broader semiconductor hierarchy, it is a digital signal processor and specialized logic IC used for video imaging, graphics, display processing, broadcast equipment, and other systems that must transform parallel pixel data at high speed. The TMC2272AKEC3 operates at 50 MHz, corresponding to a 20 ns pipelined throughput interval according to the available technical summary.
The primary feature set includes 36-bit color processing through three simultaneous 12-bit input and output channels. The converter can therefore handle three color components during each pipeline cycle rather than processing the components sequentially. Its two's-complement numerical format supports signed digital color representations, while overflow headroom in lower-resolution, user-defined coefficient modes provides additional implementation flexibility.
The TMC2272AKEC3 accepts TTL-compatible inputs and operates from a single 4.75 V to 5.25 V supply. The 120-MQFP surface-mount package provides 120 gull-wing terminals and a 28 x 28 mm body size. The verified source data identifies the package as 120-BQFP, 120-MQFP, square, and commercial temperature grade, although an exact terminal-by-terminal public pinout was not included in the supplied materials.
Typical applications include video color correction, RGB-to-YUV or YUV-to-RGB conversion, display calibration pipelines, graphics preprocessing, broadcast video equipment, and industrial imaging systems with parallel pixel interfaces. The three simultaneous channels are especially useful where color components must be converted in parallel with minimal throughput penalty. Systems still need to establish the required coefficient values and verify the converter's numerical format at the system interface.
The main design consideration is confirming that the PCB footprint and signal timing match the target 120-terminal package. Designers should also preserve adequate logic-level compatibility and account for the converter's signed input and output convention. Because the available source material does not provide a verified pin-by-pin diagram, board-level replacement should not be based on visual package matching alone.
This page consolidates the verified 50 MHz throughput, 36-bit processing capability, supply range, package information, and available price into an engineering-focused reference. It also separates verified specifications from unavailable pin-level and lifecycle data, helping procurement and design teams evaluate the TMC2272AKEC3 without treating unsupported assumptions as manufacturer specifications.

Typical Applications
TMC2272AKEC3 is suitable for 6 applications: RGB to YUV Video Conversion, YUV to RGB Display Processing, Broadcast Video Color Correction, Digital Graphics Preprocessing, Industrial Imaging Color Processing, Video Scaling and Format Conversion.
RGB to YUV Video Conversion
The TMC2272AKEC3 fits parallel RGB-to-YUV conversion because it accepts three simultaneous 12-bit channels and produces three corresponding 12-bit outputs. Its 50 MHz operating rate and 20 ns pipelined throughput interval support high-speed pixel streams, while the two's-complement numerical format helps maintain consistent signed arithmetic through the color matrix. The converter would sit between RGB source circuitry and downstream YUV processing. Designers must configure the applicable coefficients, confirm the exact supported conversion matrix, and validate output latency against the video timing budget.
YUV to RGB Display Processing
The TMC2272AKEC3 is suitable for YUV-to-RGB conversion stages in display and projection systems because its architecture processes three color components in parallel. Each 12-bit channel is handled simultaneously at up to 50 MHz, avoiding a requirement to serialize the luminance and chrominance components through separate operations. The resulting RGB outputs can feed display-format processing or pixel-generation logic. System timing must include the stated 20 ns pipelined throughput interval and account for the device's signed input and output convention.
Broadcast Video Color Correction
TMC2272AKEC3 can provide a dedicated parallel color-transformation stage in broadcast video equipment that must convert pixels between compatible color spaces. Its three simultaneous 12-bit channels map well to a three-component video datapath, while 50 MHz operation supports demanding pixel-processing rates. The TTL-compatible input interface can simplify connections with appropriately designed TTL-compatible logic. Before circuit release, engineers should verify voltage thresholds, timing margins, coefficient programming, and the exact output coding from the complete manufacturer documentation.
Digital Graphics Preprocessing
The TMC2272AKEC3 can be used ahead of display hardware to transform three-component digital graphics data before final rendering or calibration. Parallel handling of three 12-bit channels at 50 MHz makes the device relevant to high-resolution frame pipelines, while user-defined coefficient support can accommodate lower-resolution operating modes with overflow headroom. The 4.75 V to 5.25 V operating range places it in conventional 5 V digital logic systems. Integration still requires verifying the data format, coefficient implementation, latency, and 120-terminal PCB footprint.
Industrial Imaging Color Processing
The TMC2272AKEC3 is applicable to industrial imaging systems that produce parallel RGB or compatible three-component pixel data and require deterministic color-space transformation. Three simultaneous 12-bit channels support efficient component processing at 50 MHz, and the signed output format can support downstream arithmetic. The device may sit between an image sensor or frame-processing block and a display, recorder, or inspection engine. A complete design must confirm sensor-data coding, input levels, calibration coefficients, synchronization, and latency against the machine-vision frame timing.
Video Scaling and Format Conversion
The TMC2272AKEC3 can be used as the color-conversion stage in systems that retain parallel pixel data while changing color representation. Its three 12-bit input channels and three 12-bit output channels provide a symmetric 36-bit datapath, while lower-resolution operation with user-defined coefficients and overflow headroom offers flexibility when the source pipeline uses fewer effective bits. The 20 ns pipelined interval must be reflected in control timing and latency budgeting. Engineers should also verify whether external scaling logic is required because scaling is not specified in the available data.

Design Notes
Route the three parallel 12-bit input buses and three parallel 12-bit output buses with matched propagation characteristics, and keep the 50 MHz clock distribution short and symmetric. The verified data confirms a 20 ns pipelined throughput interval but does not provide detailed timing-edge limits, so timing closure must use the complete manufacturer datasheet. Maintain a continuous ground-reference path beneath the large 28 x 28 mm QFP and place bypass connections close to the supply pins once their exact positions are confirmed from the official pinout.
Do not assume that matching the 120-MQFP outline proves replacement compatibility. The replacement must also match every pin function, supply requirement, input threshold, clock definition, output coding, coefficient interface, and pipeline latency. The available evidence identifies a square 120-terminal gull-wing package and a 120-MQFP 28 x 28 mm outline, but it does not contain a verified terminal-by-terminal pinout; compare an authoritative pin drawing before approving a substitution.
Implement the source and destination interfaces for the verified two's-complement numerical format and TTL-compatible input requirement. Account for sign extension or channel alignment in the surrounding logic, and verify whether the system uses all 12 bits in each channel or a lower-resolution mode with user-defined coefficients and overflow headroom. The available summary does not specify output voltage levels or timing margins, so those details must be confirmed before final interface design.
