MK2712SLF - 35.469MHz NTSC/PAL Clock Source | Renesas
料号： MK2712SLF ✓ 量产中MK2712SLF 概述
A clock synthesizer is a timing integrated circuit that generates or organizes one or more frequency references for downstream digital and analog systems. Within the clock and timing hierarchy, it belongs to the clock generator and PLL family and ultimately to the broader timing IC category. Video clock synthesizers are used when multiple video functions must share a stable, defined timing relationship, particularly in broadcast, capture, processing, and display equipment.
The verified product listing identifies the MK2712SLF as a clock synthesizer and video IC with one channel, a 35.469 MHz nominal frequency, and an 8-SOIC package. Distributor information also describes it as an NTSC/PAL clock source. These characteristics make frequency stability, output behavior, supply requirements, and timing margins the primary engineering concerns when evaluating this device for a new video design.
The MK2712SLF is used where the system requires a dedicated video timing reference rather than a general-purpose clock. Its single-channel architecture is appropriate for designs that establish a central NTSC/PAL-related timing point and distribute that reference to other circuit blocks. Designers should confirm that the generated frequency matches every video standard and timing requirement in the target system before releasing production hardware.
Typical uses include video capture systems, broadcast-equipment clocking, NTSC/PAL-compatible processing chains, and multi-function video boards. In these applications, the clock reference establishes timing for video signal generation and downstream conversion or processing. Because different video standards use different timing parameters, a fixed 35.469 MHz source must be integrated only where its timing role is understood and validated.
The principal design consideration is verification of the complete clock path. Evaluate output frequency, tolerance, jitter, noise, supply range, and logic levels against the downstream video ICs before layout. Decoupling and return paths should follow the requirements in the manufacturer datasheet, and unused outputs or control pins must not be assigned functions without confirmation from that document.
This page combines the verified Renesas and distributor information with practical procurement context, explicit data gaps, package details, and a conservative review of available video-clock alternatives. It is designed to help engineers distinguish confirmed MK2712SLF facts from characteristics that still require datasheet-level verification.

典型应用
MK2712SLF 适用于 6 应用s: NTSC Video Clock Reference, PAL Video Processing Board, Video Capture Clocking, Broadcast Timing Distribution, Video Display Interface Timing, Video Test and Measurement Equipment.
NTSC Video Clock Reference
The MK2712SLF is a logical candidate for an NTSC-related video timing reference because the verified Mouser description identifies it as an NTSC/PAL clock source and DigiKey confirms a nominal 35.469 MHz output. It can serve as the central clock source for video-generation or processing blocks that require a common timing reference. The verified data does not state the output tolerance, jitter, logic levels, or supply range, so the circuit must be checked against the requirements of the connected video ICs and the Renesas datasheet before release.
推荐
PAL Video Processing Board
For a PAL video-processing board, the MK2712SLF provides a dedicated 35.469 MHz clock source in an 8-SOIC package, avoiding reliance on a general-purpose oscillator when the design requires a defined video timing point. Its single-channel architecture can feed a video ADC, encoder, decoder, or timing controller if their specified clock requirements match. The package width of 3.90 mm supports compact layouts, although the exact input-output timing relationship, supply limits, and jitter budget remain unconfirmed in the supplied sources.
推荐
Video Capture Clocking
The MK2712SLF can supply a common reference in a video-capture chain where analog-to-digital conversion and subsequent processing must operate from a coherent clock domain. Its 35.469 MHz nominal output is the confirmed parameter to compare with the capture controller's requirement, while the NTSC/PAL description supports evaluation for standard-definition timing. Because the available records do not provide jitter, rise/fall time, or channel-to-channel timing data, engineers should perform a signal-integrity review at the destination IC.
推荐
Broadcast Timing Distribution
Within broadcast or professional video equipment, the MK2712SLF can be evaluated as a dedicated source for a timing tree whose reference must correspond to NTSC/PAL video timing. Its single output and defined 35.469 MHz nominal frequency simplify the initial architecture when only one timing reference is required. For multi-channel equipment, however, additional distribution or synthesis may be necessary because the verified information identifies one channel only. Cable length, return path, and clock jitter should be characterized in the final chassis environment.
推荐
Video Display Interface Timing
The MK2712SLF is suitable for design evaluation where a display-facing video block requires a dedicated NTSC/PAL-related reference. The 35.469 MHz nominal output should be compared directly with the expected pixel or system timing requirement rather than assumed to satisfy every display standard. The small 8-SOIC footprint permits placement near the destination circuitry, helping reduce trace length and timing distortion. Verify output amplitude, edge quality, supply requirements, and enable or test-pin states using the manufacturer datasheet before PCB release.
推荐
Video Test and Measurement Equipment
The MK2712SLF can be investigated as a stable reference source within video test equipment intended to exercise NTSC/PAL-related timing behavior. A defined 35.469 MHz source provides a useful architectural starting point for synchronization with video processing paths, while the 8-SOIC package supports dense instrumentation hardware. Measurement uncertainty in the finished product depends on the part's unverified tolerance and jitter, so those characteristics must be taken from the Renesas documentation and included in the instrument's timing-accuracy budget.

设计说明
Place the MK2712SLF close to the video IC that consumes its clock, and keep the output trace short, direct, and surrounded by an uninterrupted ground reference. The verified 8-SOIC package is 3.90 mm wide, which permits compact placement, but a small footprint does not eliminate propagation-delay or return-path problems. Avoid routing the clock beneath noisy power stages or parallel to switching-node edges, and follow the exact layout example in the Renesas datasheet once its electrical details are available.
Use the manufacturer-specified bypass and supply connections at the IC, and account for the local power-supply noise seen at the clock-source pins. The supplied search results confirm the 35.469 MHz nominal output but do not provide supply voltage, supply current, or capacitor values. These must be obtained from the MK2712 datasheet rather than inferred from related clock ICs. Keep the clock's ground return close to the output path and evaluate whether a dedicated regulator or filtering stage is needed in a high-power video chassis.
Verify the complete output waveform at the destination IC rather than relying only on the nominal 35.469 MHz frequency. Relevant checks include frequency tolerance, jitter, edge rate, logic amplitude, and the receiver's allowable clock input range. The verified records do not quantify any of those timing parameters, so test them from the datasheet and with a representative board. If the net is long or crosses a connector, preserve a continuous return plane and consider source-series damping based on measured edge behavior.
Do not substitute an 8-SOIC clock IC solely because the package is identical. The supplied cross-reference results identify comparison candidates but do not establish identical pin assignments, supply limits, output logic levels, or timing waveforms. Before replacing MK2712SLF, compare all eight pins and the application circuits for MK5811CMILF, MK2761AS, MK2761ASLFTR, and CY25819SXC. A package match is a starting point for review, not proof of drop-in equivalence.
合规信息
The verified search results identify Renesas as the manufacturer and list the part as lead-free only in the sense that its status field is shown without a confirmed value. No definitive RoHS, REACH, AEC-Q100, halogen-free, or conflict-minerals declaration was included in the supplied data.
