MK2716S 概述
A clock synthesizer is a timing IC that generates or distributes clock signals required by digital systems. In a PLL-based implementation, a phase-locked loop compares a reference signal with a divided output and adjusts the controlled oscillator until the two signals are synchronized. Clock synthesizers belong to the clock and timing IC hierarchy and support video, communications, and other systems that require stable reference-derived timing.
The verified data identifies the MK2716S as a single PLL clock synthesizer, an HDTV clock synthesizer, and a 74.25 MHz device in an 8-pin SOIC package. These descriptions indicate a specialized timing function rather than a general-purpose oscillator or microcontroller. The exact output configuration, reference frequency, voltage ratings, jitter, pin functions, and operating limits are not present in the supplied verified records and must be confirmed in the manufacturer datasheet before design release.
The part is associated with HDTV and video clock-generation requirements. A synthesized clock can provide a controlled timing reference to video-processing chains, display equipment, converters, and related digital video systems. The 74.25 MHz designation is a concrete nominal operating point in the provided distributor record, but the supplied data does not establish tolerance, output count, or configuration details.
For PCB design, verify the exposed SOIC footprint, pin assignment, power rails, ground-return requirements, and recommended decoupling directly from the current Renesas datasheet. Do not substitute a generic clock IC solely because its frequency is similar; clock polarity, edge relationships, jitter, supply voltage, and system timing requirements must match.
This page consolidates verified distributor descriptions, manufacturer-document references, packaging information, and engineering guidance. It does not infer missing electrical specifications, and unsupported values are marked for data completion rather than guessed.

典型应用
MK2716S 适用于 6 应用s: HDTV Video Clock Generation, Video Processing Timing Reference, Display Interface Timing, Video Conversion Equipment, Consumer Video Electronics, Industrial Video Control Systems.
HDTV Video Clock Generation
The MK2716S is identified as an HDTV clock synthesizer with a nominal 74.25 MHz operating point, making it a candidate for timing-clock generation in HDTV video systems. A compatible design would use the device as the PLL clock source feeding compatible video-processing logic, converters, or display-interface circuits. The design must match the required reference input, output configuration, edge polarity, and supply conditions. Because the supplied records do not specify the complete pinout, jitter, voltage range, or reference requirements, those items must be confirmed in the Renesas datasheet before the clock is integrated into a production HDTV design.
推荐
Video Processing Timing Reference
The MK2716S can serve as a candidate timing reference for video-processing chains that require a stable, synthesized clock rather than an unconstrained free-running oscillator. Its stated 74.25 MHz nominal frequency may align with common video timing points, but frequency naming alone does not prove compatibility. The clock edge, phase relationship, jitter, supply voltage, and PLL lock behavior must be checked against the destination device specifications. Use the manufacturer datasheet to determine whether the output is single-ended or differential and how the reference clock and feedback network are configured.
推荐
Display Interface Timing
The HDTV clock-synthesizer function makes the MK2716S relevant to equipment that requires centralized clock generation for display or interface timing. In such a design, the synthesizer can provide a controlled reference to downstream digital video blocks while the system manages format changes and synchronization elsewhere. The supplied data does not identify the supported interface standard, output count, or programmable frequency range, so the part should not be treated as a universal LVDS, HDMI, or display-interface clock generator. Verify all timing and I/O specifications in the Renesas documentation before selecting it for a particular interface.
推荐
Video Conversion Equipment
A clock synthesizer can be useful in video conversion equipment where multiple digital blocks must operate from a controlled timing source. The MK2716S is described as an HDTV clock synthesizer, so it may be evaluated for a converter that uses a 74.25 MHz-related video clock domain. The available evidence does not confirm converter-specific reference requirements, output formats, or lock-time behavior. Engineers should compare the complete datasheet timing table with the converter's clock tolerance and interface specifications, then validate startup, jitter, and power sequencing on hardware before production use.
推荐
Consumer Video Electronics
The MK2716S is suitable for evaluation in compatible consumer video electronics where a dedicated clock synthesizer can simplify distribution of a stable reference signal. The verified distributor description specifically associates the part with HDTV clock synthesis, which makes it more relevant to video timing than generic digital logic. However, the supplied records do not confirm consumer-temperature qualification, lifecycle status, output voltage levels, or power consumption. Confirm those details and check the latest manufacturer documentation before using the device in a cost-sensitive or space-constrained consumer design.
推荐
Industrial Video Control Systems
The MK2716S may be considered for industrial video-control equipment that derives a deterministic clock for image acquisition, processing, and display synchronization. A PLL-based clock synthesizer can help centralize timing distribution, but the exact reference and feedback arrangement must be designed from verified electrical specifications. The supplied data does not establish industrial temperature range, electromagnetic-emissions performance, radiation tolerance, or AEC-Q100 qualification. Therefore, use the MK2716S for industrial video timing only after checking the operating-temperature, supply, jitter, and lifecycle requirements against the system specification.

设计说明
Begin the layout by confirming the official 8-pin SOIC footprint and pin numbering from the current Renesas package drawing. The verified data establishes an 8-pin SOIC and a 3.90 mm package width, but it does not provide pad dimensions or pin names. Do not release a footprint or assign power, ground, reference, and output pins until those details are verified from the datasheet and package documentation.
Treat the clock net as a timing-sensitive signal and keep the route short, continuous, and referenced to a low-impedance ground plane. The supplied data does not state the output edge rate, jitter, output impedance, or signal-level standard. These missing parameters must be established before setting trace width, termination, shielding, or impedance targets. Validate the final layout with the destination video IC's clock-input requirements and measurement equipment.
Verify the MK2716S supply voltage, current consumption, and decoupling requirements before adding power circuitry. PLL-based clock synthesizers can be sensitive to supply noise and startup sequencing, but the provided search excerpts do not include the electrical characteristic table. Use the manufacturer datasheet for capacitor values, allowed supply range, power-up requirements, and any PLL lock or fault behavior rather than extrapolating from the 74.25 MHz operating point.
Do not use a generic 74.25 MHz oscillator as an electrical substitute for the MK2716S. The target is identified as a clock synthesizer, which may require a reference input and specific feedback configuration. Before replacement, verify reference frequency, output count, edge polarity, supply voltage, PLL loop requirements, package pinout, and system timing margins. The supplied cross-reference results do not establish a validated drop-in replacement.
合规信息
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields must be confirmed from the current manufacturer or distributor documentation.
