TMC2272AKEC2 - 50MHz 36-Bit Video Converter | onsemi
MPN: TMC2272AKEC2 ✓ AktifTMC2272AKEC2 Ringkasan
A digital colorspace converter is a specialized signal-processing IC that transforms color data between component spaces or performs programmable matrix operations on digital RGB or luminance-chroma signals. Within the broader semiconductor hierarchy, it belongs to the video-processing IC and interface-IC categories rather than analog amplifiers or general-purpose logic. Such converters are used when a video system needs controlled transformation of color coordinates, channel weighting, or matrix coefficients before display or downstream processing.
The TMC2272AKEC2 provides three simultaneous 12-bit channels at both the input and output, supporting the full 36-bit word width in one pipeline stage. It also supports lower-resolution operation with user-defined coefficients, with overflow headroom available in those modes. TTL-compatible inputs simplify interfacing with compatible digital video logic, while the pipelined architecture supports sustained 50 MHz operation without changing the external 120-MQFP footprint.
The part is identified as a linear video-processing IC and is distributed as TMC2272AKEC2 by onsemi. Distributor records also associate the device with Fairchild Semiconductor and Raytheon part records, reflecting its commercial lineage rather than a different device function. The EC2 ordering suffix appears in the exact MPN retained by current distributor listings, and the supplied records identify the physical package as 120-MQFP, 28 mm by 28 mm.
Typical uses include broadcast and professional video infrastructure, digital color processing, luminance-to-chroma or RGB matrix conversion, test equipment, and embedded video systems that need simultaneous signed 12-bit channel arithmetic. Because the converter is digital, performance depends on clocking, input-output timing, coefficient configuration, and termination discipline rather than analog gain settings. The 50 MHz pipeline rate supports high-volume pixel processing while limiting data buffering requirements in multi-stage video paths.
Designers should treat the datasheet as the controlling source for pin assignments, timing, coefficient tables, and electrical limits because those details were not included in the supplied verified records. The three channel groups should be routed with matched impedance, clocks should remain clean, and unused signals should follow the manufacturer’s termination and grounding guidance. The MQFP package also requires careful lead inspection and adequate board cleanliness because its closely spaced leads can complicate assembly and rework.
This product page combines the verified 50 MHz, 36-bit, three-channel, and package details with distributor pricing, sourcing links, application guidance, and replacement constraints. It also distinguishes verified orderable alternatives from unsupported package or timing substitutions so engineers can make a traceable procurement decision rather than relying on a generic cross-reference match.

Aplikasi Biasa
TMC2272AKEC2 patut untuk 6 aplikasis: Digital Broadcast Video Processing, RGB and Component Color Conversion, Video Test and Measurement Equipment, Professional Audio and Video Systems, Industrial Video Inspection Systems, High-Speed Digital Color Processing.
Digital Broadcast Video Processing
The TMC2272AKEC2 fits professional digital video paths that require deterministic color arithmetic at a 50 MHz pipeline rate. Its three simultaneous 12-bit input channels and three 12-bit outputs preserve a complete 36-bit working width, allowing signed luminance and chroma calculations without splitting the operation across separate devices. The converter is placed between video sources and downstream processing or display stages, where coefficient tables and channel alignment determine the transformation. Two’s-complement data supports signed calculations, while TTL-compatible inputs simplify interfacing with compatible digital sources. The principal design benefit is throughput: 50 MHz operation corresponds to a 20 ns pipeline period, allowing sustained processing without requiring a large frame buffer. Engineers must still verify clock timing, coefficient programming, and the complete 120-MQFP pin map from the manufacturer datasheet.

RGB and Component Color Conversion
The TMC2272AKEC2 is appropriate for systems that must transform RGB, component, luminance, or chroma data using programmable color coefficients. Its three-channel architecture directly supports simultaneous color channels, while the verified 36-bit width provides substantially more headroom than an 8- or 10-bit implementation. Lower-resolution modes add user-defined coefficients and overflow headroom, which can simplify fixed-point calculations when full 36-bit precision is unnecessary. In a broadcast or industrial video system, the IC would typically sit after input normalization and before encoding, display conversion, or measurement. The 50 MHz pipeline supports rapid channel updates, but coefficient scaling and signed-number headroom must be checked carefully. Layout should minimize clock and data skew across the densely pinned 120-MQFP device while preserving the manufacturer’s recommended termination.

Video Test and Measurement Equipment
The TMC2272AKEC2 can support color-math test points in video analyzers, waveform products, and automated video test systems. Three simultaneous 12-bit channels allow a test fixture to apply controlled transforms to digital video data while observing downstream behavior, and the 50 MHz operating rate provides useful throughput for repetitive measurements. User-defined coefficients in lower-resolution modes make it possible to create standardized gain and mixing matrices without sacrificing signed arithmetic. A practical implementation would place the converter between a controllable digital pattern source and the analyzer or device under test. Engineers should verify the exact coefficient table format, output latency, clock recovery behavior, and numeric overflow boundaries using the TMC2272AK datasheet. Those details are necessary to distinguish intended arithmetic from pipeline delay during automated measurements.

Professional Audio and Video Systems
The TMC2272AKEC2 can serve the video side of integrated professional media systems where synchronized digital color data must be transformed before presentation or recording. Its full 36-bit processing width and simultaneous three-channel operation are useful when the system must preserve precision through matrix calculations, while the 50 MHz pipeline rate aligns with demanding synchronous video architectures. The device should be positioned at a stable digital-video boundary, with clocking and data buses controlled to avoid skew-induced channel errors. This application is particularly relevant to professional monitoring and media-processing equipment where a separate color-space conversion stage can simplify downstream devices. System designers must confirm voltage compatibility, output timing, and coefficient control interfaces from the manufacturer documentation. The verified snippets do not establish power consumption or operating-temperature limits, so thermal and reliability review requires additional sourcing.

Industrial Video Inspection Systems
The TMC2272AKEC2 is suited to industrial inspection systems that perform programmable color transformations on camera or scanner data. Three simultaneous 12-bit channels support RGB or other color-vector operations, while user-defined coefficients in reduced-resolution modes allow fixed-point matrix calculations tailored to a particular sensor or optical setup. The 50 MHz rate allows the color stage to operate continuously alongside digital image processing rather than serving only a low-speed setup function. In such a system, the converter may sit between an image sensor interface and a processor, FPGA, or downstream image processor. Coefficient changes should be scheduled around valid video windows and verified for overflow, particularly when lowering effective bit depth. Because the supplied data does not state supply voltage, power consumption, or environmental ratings, an industrial deployment must obtain the complete manufacturer datasheet and confirm those constraints before design release.

High-Speed Digital Color Processing
The TMC2272AKEC2 provides a compact implementation for high-speed digital color math where throughput and signed precision matter more than analog integration. Its 50 MHz pipelined operation produces a 20 ns pipeline period, and its three 12-bit channels support parallel color processing without requiring three separate converter packages. The IC is particularly useful in laboratory instruments, video routers, frame-processing cards, and digital display test systems that need programmable transformations close to the data source. A successful design must account for input and output latency, coefficient update timing, synchronous clock distribution, and simultaneous-switching noise around the 120-MQFP device. The verified source describes the digital arithmetic but does not provide AC timing tables, power limits, or a complete pinout. Those omissions must be resolved from the manufacturer datasheet before schematic capture or high-speed layout signoff.

Catatan Desain
Route the 50 MHz clock and the three synchronous 12-bit data buses with controlled length and skew because simultaneous channel operation can turn trace mismatch into color errors. Keep the clock away from coefficient-control and unused-input nets, use a continuous ground reference beneath the device, and follow the manufacturer’s package-specific land pattern. The supplied verified records identify a 120-MQFP, 28 mm by 28 mm package but do not provide the complete pinout, so the mechanical footprint must be checked against the current manufacturer drawing rather than inferred from a generic PQFP library.
Do not treat the TMC2272AKEC3 name in a supplier grouping as proof of drop-in equivalence. The verified records establish the TMC2272AKEC2’s 36-bit, 50 MHz, three-channel behavior but do not publish the AKEC3 pinout, timing, voltage, or qualification differences. Before substitution, compare every power, ground, clock, data, and control connection against both datasheets and verify that coefficient programming and pipeline latency remain equivalent. This prevents a nominal ordering-code change from introducing an unreviewed PCB or behavioral risk.
Account for propagation delay and pipeline alignment when connecting the converter to surrounding video logic. The verified 20 ns pipeline period describes the 50 MHz processing rate, but it is not a substitute for the detailed input-to-output timing table. Use matched data routing, continuous reference planes, and the datasheet-recommended input and output termination. Where coefficients change during active video, synchronize the update to a valid boundary and verify overflow behavior in the selected lower-resolution mode.
Maklumat Kesediaan
The supplied verified snippets do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements for TMC2272AKEC2. Compliance must be verified using the current manufacturer product documentation or declaration.
