MK2716SLF - 74.25MHz HDTV Clock Synthesizer | Renesas
MPN： MK2716SLF ✗ 停產MK2716SLF 概覽
A clock synthesizer is a timing IC that derives one or more predictable clock outputs from a stable frequency source. Within the clock and timing hierarchy, a clock synthesizer belongs to oscillator and clock-generation circuitry, which supports digital logic, video processing, communications, and other sequential systems. The MK2716 series is specifically described by Renesas as an HDTV clock synthesizer and is intended to replace discrete crystal-and-oscillator arrangements with a dedicated timing component where appropriate.
The verified product information establishes a 74.25 MHz output, one available clock output, and a 3 V to 5.5 V operating supply range. These three characteristics make the device relevant to legacy or specialized HDTV designs that operate from standard low-voltage rails. Because the supplied snippets do not state the complete electrical characteristics, designers should consult the Renesas MK2716 datasheet before establishing output amplitude, input-frequency tolerance, jitter, power consumption, temperature limits, or timing margins.
The MK2716's fixed clock output simplifies system partitioning when downstream circuits already require the 74.25 MHz HDTV reference. It can feed digital video timing, synchronization, interface-conversion, or processing blocks, provided their input levels and clock requirements match the device. Compared with a discrete crystal oscillator network, an integrated synthesizer can reduce component count and standardize clock generation, but it must still be supported by correct decoupling and controlled board layout.
Typical implementation places the clock generator near the loads it serves and connects its supply to a clean 3 V to 5.5 V rail. Short traces help limit added delay and susceptibility to noise. The SOIC package requires adequate spacing from board edges and neighboring components, while the power and ground pins must follow the manufacturer's recommended layout. Load capacitance, fanout, and termination should be checked against downstream requirements.
The key design trade-off is specialization. A dedicated 74.25 MHz HDTV clock synthesizer is appropriate when the system requires that reference, but it is not a universal programmable clock solution. Confirm source frequency, output count, supply voltage, logic levels, package, and pinout against the current manufacturer datasheet before layout release. This page distinguishes verified facts from parameters that were not present in the supplied data.

典型應用
MK2716SLF 適用於 6 應用s: HDTV Video Timing, Digital Video Processing, Video Data Conversion, Display Timing Control, Video Test Equipment, Industrial Video Control.
HDTV Video Timing
MK2716SLF fits systems that require a dedicated 74.25 MHz HDTV clock and operate from a 3 V to 5.5 V rail. Place the device near the receiving timing blocks and route the output over a short, controlled trace. Its one-output arrangement favors a centralized reference architecture rather than a multi-clock distribution network. Because jitter, output level, and load limits were not included in the verified snippets, the designer must verify timing margin and receiver thresholds in the Renesas MK2716 datasheet before release.
推薦
Digital Video Processing
A 74.25 MHz reference can support clocking inside compatible digital video processing chains, provided input thresholds, fanout, and timing requirements match. MK2716SLF's dedicated HDTV role makes it more targeted than a general oscillator, while the 8-SOIC footprint supports conventional surface-mount assembly. Keep the clock route away from switching regulators and high-current video outputs, and compare the device's undocumented-in-source jitter against downstream pixel-clock tolerances.
推薦
Video Data Conversion
MK2716SLF can provide the fixed video timing reference to a compatible conversion chain while operating across the verified 3 V to 5.5 V supply range. The one available output should be routed only to loads whose input capacitance and thresholds are verified. Short traces and a quiet reference plane help preserve clock quality between the SOIC device and the converter. Use an oscilloscope at the receiving IC to validate amplitude and edge behavior during prototype testing.
推薦
Display Timing Control
The 74.25 MHz output from MK2716SLF is relevant to display systems built around the associated HDTV timing domain. It can serve as a shared reference only when every receiver supports the resulting logic level and edge rate. Route the clock away from display power stages and connectors where return currents could disturb timing. The supplied data confirms the target frequency and package, but not output drive or jitter, so those values require direct manufacturer confirmation.
推薦
Video Test Equipment
MK2716SLF's fixed HDTV frequency can support specialized video test and measurement modules that need a repeatable reference. The 8-SOIC surface-mount package is convenient for compact instrument electronics, while the one-output configuration suits a single primary timing domain. Validate output amplitude, jitter, and reference stability under the actual load before using it as a measurement reference. Supply decoupling and return-path planning should follow the official datasheet and instrument layout practices.
推薦
Industrial Video Control
A 74.25 MHz HDTV timing reference may fit industrial inspection or machine-vision electronics that retain an HDTV video timing chain. MK2716SLF's 3 V to 5.5 V operating range supports common embedded rails, although industrial temperature qualification was not supplied. Protect the clock path from motor, relay, and switching-power stages, and verify long-term drift and startup settling during system qualification. Do not infer industrial or automotive suitability from the application alone.

設計說明
Place the 8-SOIC device close to the receiving clock input and route the 74.25 MHz signal over the shortest practical trace. Keep the path away from switching-regulator switches, inductors, motor drivers, and high-current return paths. Use a continuous reference plane where practical and avoid unnecessary test pads or stub branches that can increase edge degradation. Exact trace geometry and grounding must be checked against the complete Renesas datasheet.
Power MK2716SLF from a stable rail within the verified 3 V to 5.5 V range and place local decoupling at the device pins. The provided source does not specify capacitor values, output-current capability, or startup requirements, so these must be obtained from the manufacturer datasheet rather than assumed. Keep the clock generator on a quieter rail than noisy video power stages when the system architecture permits.
Do not assume that similar MK2716 suffixes are automatically drop-in equivalents. The cross-reference snippets distinguish tube and tape-and-reel forms and even report uncertain lifecycle states, so verify the exact ordering code, pinout, frequency, supply range, and logic levels before substitution. A matching SOIC outline does not prove electrical or pin compatibility. For production continuity, request a Renesas-approved cross-reference and current lifecycle confirmation.
合規資訊
Compliance status was not explicitly present in the verified search snippets. One third-party comparison describes MK2716SLFTR as lead-free, but that designation was not applied to MK2716SLF without direct manufacturer evidence. Compliance fields therefore remain unknown.
