TMC2072KHC 概要
A video digitizer is an interface IC that converts analog composite-video signals into digital pixel data for storage, transmission, monitoring, or image-processing systems. The TMC2072KHC combines analog input selection, clamping, gain adjustment, synchronization handling, timing generation, quantization, and digital output in one device. This integration reduces the number of external functional blocks required in professional video equipment.
The 3-channel video input multiplexer supports selection among multiple composite-video sources. Analog and digital video clamp functions establish a stable reference level before sampling, while automatic gain adjustment compensates for amplitude variation. Sync detection and separation extract horizontal and vertical timing information for genlocking the digitizer to the incoming video source.
According to the manufacturer datasheet description, the on-chip PLL generates a line-locked pixel clock for the internal 8-bit analog-to-digital converter and a double-speed register clock for transferring data to subsequent video-processing logic. This timing architecture is central to converting analog baseband composite NTSC or PAL video into its digital equivalent.
Typical uses include broadcast video monitoring, video switching systems, frame synchronizers, production test equipment, industrial inspection, and legacy video capture. The same-package requirement and available board-level evidence must be considered before selecting a replacement.
Designers should preserve the analog input, clock, PLL, and digital-output layout recommended in the datasheet and verify timing margins at the intended NTSC or PAL line rate. The verified data does not provide complete pin definitions, absolute maximum ratings, or all timing values in the supplied snippets.
This page combines verified distributor information, datasheet search results, package identity, and design-oriented engineering guidance while clearly identifying parameters that require direct confirmation from the manufacturer datasheet.

主な用途
TMC2072KHC の用途: 6 件s: Broadcast Video Monitoring, Analog Video Frame Synchronization, Video Switching Systems, Legacy Video Capture, Industrial Video Inspection, Video Test and Measurement.
Broadcast Video Monitoring
The TMC2072KHC fits broadcast monitoring equipment that accepts standard analog baseband composite video and needs a stable digital representation for display, recording, or downstream analysis. Its 3-channel video multiplexer allows one digitizer to select among multiple sources, while the two-stage analog and digital clamp helps establish repeatable signal levels before quantization. Horizontal and vertical synchronization separation and the on-chip PLL provide line-locked timing. The verified 8-bit conversion is appropriate for legacy monitoring paths where the system does not require the resolution of a modern high-definition video interface.
おすすめ
Analog Video Frame Synchronization
The TMC2072KHC is suitable for a frame-synchronization subsystem that must lock digital sampling to an external composite-video source. Its genlocking architecture uses extracted synchronization information to generate a line-locked pixel clock, helping downstream memory, encoders, or processors receive repeatable timing. The 3-channel input multiplexer can support source selection in professional equipment, while automatic gain adjustment handles amplitude variation. Engineers should verify line-rate range, pixel-clock requirements, latency, and register compatibility in the manufacturer datasheet before finalizing the system timing.
おすすめ
Video Switching Systems
A 3-channel input multiplexer makes the TMC2072KHC relevant to video switching and routing equipment where several composite sources must be digitized for monitoring or processing. The integrated clamp and automatic gain adjustment reduce the amount of external conditioning required for changing source amplitudes, while sync separation gives the system a timing reference for each selected source. The device is intended for standard NTSC and PAL composite video, so the source signals must remain within the acquisition bandwidth and amplitude range specified by the manufacturer datasheet.
おすすめ
Legacy Video Capture
The TMC2072KHC can serve as the acquisition front end in legacy video capture equipment that digitizes NTSC or PAL composite input for storage or processing. Its 8-bit ADC and genlocking function produce a digital video stream synchronized to the source timing, while the three-channel multiplexer supports multiple inputs. This is useful for industrial inspection, studio accessories, and test systems that must interface with existing analog-video equipment. The system must account for the documented latency, required clocking, output timing, and available board area of the 100-MQFP package.
おすすめ
Industrial Video Inspection
The TMC2072KHC is applicable to industrial inspection equipment that receives standardized composite video from cameras or test fixtures and requires deterministic digital acquisition. The genlocking and synchronization functions help align samples to each video line, while automatic gain adjustment accommodates signal-level variation from long or variable cable runs. The 8-bit converter can feed a processor, image-memory device, or communication stage. Cable shielding, grounding, input protection, and analog filtering remain important because composite-video integrity affects sync separation and the validity of the digitized pixels.
おすすめ
Video Test and Measurement
The TMC2072KHC can support video test equipment that measures or monitors NTSC and PAL composite signals after synchronization and digitization. Its horizontal and vertical sync separation provides useful timing information, and the PLL-derived clock creates a stable sampling reference for the 8-bit converter. The 3-channel multiplexer allows a single instrument to inspect several inputs. Test software must account for the device’s digital output timing and register interface, while the analog front end must preserve signal amplitude and bandwidth for accurate measurements.

設計ノート
Treat the three analog video inputs as high-value, timing-sensitive signals. Route them away from the pixel clock, register clock, and digital output paths, use a continuous ground reference, and keep input filtering and termination consistent with the manufacturer’s recommended application circuit. Composite-video timing errors can move sync levels and distort the recovered pixel stream even when the ADC resolution is adequate.
Use a supply within the verified 4.75 V to 5.25 V range and place bypass capacitors close to the supply and ground pins. Separate analog and digital return paths where the datasheet layout allows, and avoid routing high-current digital return currents beneath the video and PLL areas. The supplied data does not provide the required capacitor values, so use manufacturer recommendations rather than estimated values.
The TMC2072KHC uses synchronization-derived timing and an on-chip PLL for pixel-clock generation. Preserve short, controlled-impedance routes for clock-related signals, avoid stubs and long branches, and follow the manufacturer’s recommended placement for external timing components. Because the exact pinout and loop-filter requirements were not included in the supplied data, do not finalize placement without checking the current datasheet.
Do not treat a generic video ADC as a drop-in replacement. The TMC2072KHC requires compatible multiplexing, clamping, gain control, sync separation, PLL timing, register behavior, and 100-MQFP pin connectivity. Confirm analog bandwidth, supply rails, clock requirements, output timing, and exposed or non-exposed package details before using any substitute.
