TMC2272AH5C2 - 36-Bit 50 MHz Color Converter | Fairchild Semiconductor
Артикул: TMC2272AH5C2 ✓ АктивенTMC2272AH5C2 Обзор
A digital colorspace converter is a signal-processing IC that transforms color-component data using programmable arithmetic coefficients. In the product hierarchy, it is an interface IC, a video-processing IC, and ultimately a digital signal-processing semiconductor. The converter can support programmable color correction, matrix conversion, and related RGB-component transformations when its coefficient ports are driven by an external control system.
The TMC2272AH5C2 provides 50 MHz operation, corresponding to a 20 ns pipelined throughput. Its three 12-bit input ports accept two's-complement integer data, while its three 12-bit output ports use the same numeric format. This arrangement allows three simultaneous 12-bit channels and a combined 36-bit color word. User-defined coefficients are represented as 10-bit two's-complement fractional values.
The device supports TTL-compatible inputs and provides overflow headroom when it is operated at lower numerical resolution. The overflow-headroom feature is useful when intermediate calculations require additional range beyond the selected output resolution. Pipeline architecture supports sustained parallel data processing rather than requiring the converter to wait for a full multi-channel operation before accepting another input set.
Typical applications include RGB color-space transformation, programmable video color correction, digital imaging pipelines, broadcast video processing, and industrial vision systems requiring three parallel color channels. The 36-bit parallel interface and 50 MHz pipelined operation suit systems that convert three-component color data between numeric spaces without introducing a serial protocol bottleneck.
PCB design should account for the large 120-pin PGA footprint, high pin count, and numerous data and coefficient connections. Designers should follow the manufacturer's pinout and recommended decoupling guidance directly because the supplied web results do not expose a complete verified pin list, power requirements, or recommended component layout values.
This page combines the verified 50 MHz throughput, 36-bit color width, three-channel I/O architecture, 10-bit coefficient format, package information, distributor availability, and cross-reference findings with practical design guidance. It also distinguishes confirmed operating facts from parameters that still require confirmation from the original manufacturer datasheet.

Типичное применение
TMC2272AH5C2 подходит для 6 применениеs: Programmable RGB Color-Space Conversion, Broadcast Video Color Correction, Industrial Machine-Vision Preprocessing, Digital Imaging Pipeline Color Matrix, Legacy RGB Video Interface Conversion, High-Speed Video Color Calibration System.
Programmable RGB Color-Space Conversion
The TMC2272AH5C2 fits parallel RGB color-space conversion because it processes three simultaneous 12-bit channels and exposes three 10-bit fractional coefficient inputs. According to the Fairchild Semiconductor manufacturer datasheet, the data paths accept and produce two's-complement integer values, allowing an upstream processor to configure a transformation matrix without changing the converter hardware. The 50 MHz rate and 20 ns pipelined throughput provide sustained triple-channel operation. The main design consideration is numeric headroom: lower-resolution operation should preserve the available overflow margin so intermediate sums do not clip.
Рекомендуется
Broadcast Video Color Correction
The TMC2272AH5C2 is suitable for broadcast color correction when an existing video architecture carries three parallel component channels at up to 50 MHz. The verified 12-bit signed inputs, 12-bit signed outputs, and three user-defined coefficients allow calibration matrices to be adjusted in real time. Its 36-bit aggregate color width and stated 64-Giga-color capacity suit multi-bit video processing, while TTL-compatible inputs simplify interfacing with legacy logic. Designers should verify the original electrical timing table and external coefficient-control implementation before using the device in a new broadcast design.
Рекомендуется
Industrial Machine-Vision Preprocessing
The TMC2272AH5C2 can perform color normalization or channel transformation ahead of an industrial vision decision stage. Three simultaneous 12-bit channels avoid serializing each color component independently, while the 50 MHz pipelined operation can accept new data every 20 ns under the stated operating condition. The programmable 10-bit fractional coefficients permit sensor-specific color balancing without replacing the converter. Because the package is a large through-hole 120-pin PGA, system designers should reserve the footprint and confirm connector, thermal, and signal-integrity requirements early in the PCB plan.
Рекомендуется
Digital Imaging Pipeline Color Matrix
The TMC2272AH5C2 is appropriate for an imaging pipeline that requires a programmable three-component color matrix between capture and display stages. According to the Fairchild Semiconductor manufacturer datasheet, each coefficient port accepts a 10-bit two's-complement fractional value, allowing distinct weighting for the three simultaneous channels. Signed 12-bit integer inputs and outputs maintain a consistent numeric representation throughout the conversion. The implementation should constrain coefficients to the supported range, include overflow headroom in lower-resolution modes, and follow the manufacturer's timing and pinout documentation during layout.
Рекомендуется
Legacy RGB Video Interface Conversion
The TMC2272AH5C2 can bridge a legacy parallel RGB architecture when the destination requires a different programmable color mapping. Its three 12-bit input ports and three 12-bit output ports operate concurrently, and the 50 MHz pipelined throughput supports high-rate parallel streams. TTL-compatible inputs are useful when interfacing to older logic families, while the 20 ns throughput period provides a clear basis for timing-budget review. Retrofitting remains a specialized task because the 120-pin PGA footprint and detailed electrical requirements must be reconciled with the original board and source-device levels.
Рекомендуется
High-Speed Video Color Calibration System
The TMC2272AH5C2 supports calibration systems in which three primary-color channels must be continuously scaled or mixed. The three 10-bit fractional coefficient inputs allow calibration values to be changed by an external controller, while the 36-bit parallel datapath processes all color components at once. At a 50 MHz maximum rate, the converter can sustain a 20 ns pipelined cycle for high-speed streams. Practical implementation still requires verified clocking, input/output timing margins, grounded return paths, and the manufacturer's recommended bypass arrangement around this high-pin-count PGA device.

Заметки по проектированию
Reserve the complete 120-pin through-hole PGA footprint, including the specified 34.16 x 34.16 mm package dimensions, before routing the board. Because this converter exposes three 12-bit data inputs, three 12-bit data outputs, and three 10-bit coefficient inputs, pin-count errors can create seemingly random arithmetic results. Compare every PCB land and connector assignment directly with the manufacturer pinout, and verify the package variant at procurement because the search results use both plastic PGA and related package descriptions.
Preserve the 50 MHz operating limit by controlling clock and data-edge skew according to the manufacturer timing diagram. The converter has a stated 20 ns pipelined throughput period, but that value alone does not establish setup and hold margins for the complete board. Use short, matched routing for related channel groups, provide solid ground references, and keep coefficient-control signals away from high-speed data nets where practical. Validate the final interface with realistic source and output loading rather than relying only on nominal component timing.
Do not treat the coefficient inputs as ordinary integer data. According to the Fairchild Semiconductor manufacturer datasheet, coefficient ports always use a 10-bit two's-complement fractional representation, whereas the three data input and output ports use two's-complement integers. Mixing these formats can invert signs or scale channels incorrectly. Also preserve overflow headroom when selecting a lower working resolution, because the verified data specifically identifies overflow headroom as available in lower-resolution operation.
Confirm the exact supply-voltage tolerance, power dissipation, and recommended bypass capacitors from the original manufacturer datasheet before schematic release; those values are not exposed in the supplied search excerpts. A 50 MHz video converter can require a carefully partitioned power and ground network even when its data arithmetic is parallel. Follow the datasheet's decoupling topology and do not infer supply requirements from the 50 MHz clock or 36-bit color width, since operating frequency alone does not determine power consumption.
