TMC2246AH5C - 11x10-Bit 60MHz Digital Filter | onsemi
MPN: TMC2246AH5C ✓ فعالTMC2246AH5C نمای کلی
A digital filter is a signal-processing integrated circuit that performs arithmetic operations on sampled data rather than relying solely on passive or analog components. The TMC2246AH5C belongs to the broader digital signal processing IC hierarchy, where multiply-accumulate operations implement finite impulse response filtering and related image-processing functions. Its stated application context is industrial control, precise signal processing, and electronic noise-reduction systems.
The device provides a 60 MHz computation rate alongside 60 MHz data and coefficient input paths. Four individual 10-bit multipliers support parallel coefficient processing, while the 25-bit accumulator provides additional internal range for intermediate arithmetic. Input and output data latches include user-configurable behavior, enabling synchronization between the filter and surrounding digital circuitry. The supported data formats include fractional and integer two's-complement representations.
Technically, the TMC2246AH5C is positioned as a dedicated image-filter processor rather than a general-purpose microcontroller or FPGA. Its four multipliers and 25-bit accumulator form the arithmetic core used to combine input samples and filter coefficients. The 11 x 10-bit architecture and 60 MHz operating rate target real-time image filtering where processing throughput, fixed-point data interpretation, and deterministic parallel arithmetic are important.
The listed application areas include industrial-control signal conditioning, image filtering, noise reduction, and other electronic systems requiring precise fixed-point processing. Such uses benefit from dedicated multiplier-accumulate hardware because it reduces the processing burden associated with implementing repeated coefficient calculations in general-purpose control logic. Integration into a larger system still requires correct clocking, data-latch configuration, and compatible fixed-point data formats.
Designers should verify the complete manufacturer datasheet before layout because the supplied data identifies a 120-pin PGA package but does not expose the pinout, pin functions, supply voltages, clocking limits, or electrical characteristics. The package should therefore be treated as a 120-pin PGA with no schematic-level pin substitutions assumed. PCB planning should preserve the device's high-speed digital interface and provide a controlled return path for clock and data signals.
This product page consolidates the verified 11 x 10-bit architecture, 60 MHz processing capability, multiplier count, accumulator width, supported data formats, package information, and source links. It also distinguishes documented specifications from engineering details that still require confirmation from the manufacturer datasheet or a qualified distributor.

کاربردهای معمول
TMC2246AH5C مناسب است برای 6 کاربردs: Industrial Image Filtering, Precision Signal Conditioning, Electronic Noise Reduction, Video Processing Interface, High-Rate Digital Filter Node, Legacy Control-System Filter.
Industrial Image Filtering
The TMC2246AH5C fits industrial image-filtering systems that require deterministic fixed-point arithmetic at high throughput. Its 60 MHz computation rate, 60 MHz data and coefficient inputs, four 10-bit multipliers, and 25-bit accumulator provide a dedicated architecture for repeated coefficient calculations. A system designer can place sampled image data and coefficients into the input latches, process them through the multiplier-accumulator path, and capture results through the configurable output latches. Before implementation, verify the complete coefficient-loading sequence, clock relationships, output timing, and data scaling in the manufacturer datasheet.
Precision Signal Conditioning
The TMC2246AH5C is applicable to precise signal-conditioning paths where sampled data must be combined with coefficients at a repeatable computational rate. Its 11 x 10-bit architecture, four 10-bit multipliers, and 25-bit accumulator support parallel filtering operations without assigning those calculations to a general-purpose microcontroller. The 60 MHz data and coefficient input capability can support high-rate streams when external circuitry provides compliant timing. Engineers should validate supported filter structures, coefficient precision, overflow behavior, and output latency before replacing an existing digital signal-processing implementation.
Electronic Noise Reduction
The TMC2246AH5C can serve as the fixed arithmetic core in electronic noise-reduction systems that implement their filtering function with sampled coefficients and data. The dedicated four-multiplier structure and 60 MHz computation rate are relevant when multiple coefficient terms must be evaluated rapidly, while the 25-bit accumulator provides headroom for intermediate results. Integration requires careful mapping of fractional or integer two's-complement values because different system scaling conventions can materially change filter behavior. Confirm rounding, saturation, latching, and timing details from the manufacturer datasheet.
Video Processing Interface
TMC2246AH5C is categorized as a video IC and described as an image-filter processor, making it relevant to specialized video-processing equipment built around the original 11 x 10-bit architecture. Its 60 MHz computation rate and 60 MHz input rates can support parallel real-time filtering stages, while four multipliers support coefficient-based operations. A modern video system may use more flexible programmable devices, but the TMC2246AH5C may be preferable for maintaining a qualified legacy signal chain. Exact video timing, synchronization, and pin-level interfaces remain to be confirmed from the datasheet.
High-Rate Digital Filter Node
The TMC2246AH5C can serve as a high-rate digital filter node in a larger signal-processing system that supplies synchronized data and coefficients. Its 60 MHz computation rate matches the documented data and coefficient input rate, while the 25-bit accumulator allows intermediate arithmetic beyond the 10-bit multiplier resolution. The four multipliers provide parallel coefficient resources within one dedicated device. A practical implementation must confirm allowable clock jitter, setup and hold timing, latch enable behavior, and output synchronization, none of which can be inferred safely from the supplied search snippets.
Legacy Control-System Filter
The TMC2246AH5C is appropriate for preserving legacy industrial control and electronic noise-reduction functions when its original 120-pin PGA implementation is already embedded in the system architecture. Dedicated filtering hardware can maintain the established computational behavior without redesigning the surrounding control board around a different DSP. Because the package and architecture are unusual compared with modern leaded or fine-pitch alternatives, replacement planning should focus on schematic-level equivalence rather than headline clock rate. Confirm power rails, pin assignments, timing, and coefficient format before using another part.

یادداشت‌های طراحی
Do not assume that a generic 120-pin PGA alternative is pin compatible. A valid replacement must reproduce the power pins, grounds, clock inputs, data buses, coefficient interfaces, control signals, and latch timing of the original TMC2246AH5C. The supplied cross-reference search did not identify a verified drop-in part, so schematic comparison and manufacturer confirmation are required before substitution.
Treat the documented 60 MHz data and coefficient input rates as layout constraints. Route clock, data, and coefficient nets over a continuous reference plane, minimize stub branches, and maintain tightly controlled return paths. The supplied excerpts do not state setup, hold, or jitter limits, so use the manufacturer timing specification to determine trace length, termination, and source synchronization rather than relying on generic FPGA guidance.
Confirm coefficient scaling and the selected fractional or integer two's-complement interpretation before filtering data. A mismatch between input interpretation and the 25-bit accumulator convention can alter gain, phase, and overflow behavior even when the clocking is correct. Reproduce the original system's coefficient-loading sequence and output rounding rules, then compare known input vectors before approving a replacement or board revision.
