MK2727STR - 27MHz PLL Clock Synthesizer | Renesas (Tape & Reel)
MPN: MK2727STR ✗ Cuối đờiMK2727STR Tóm tắt
A PLL clock synthesizer is a clock-and-timing integrated circuit that generates, conditions, or multiplies timing references for digital and RF systems. The MK2727STR combines a PLL clock synthesizer with VCXO behavior, placing it within the broader hierarchy of clock management, timing control, and semiconductor signal-processing devices. This type of component is relevant when a system needs frequency flexibility, stable clock distribution, or a local oscillator rather than a fixed passive resonator alone.
The principal verified feature set is compact but application-defining: a 27 MHz operating reference, VCXO functionality, PLL clock synthesis, and an 8-SOIC package. The available distributor listings describe the part as suitable for clock-generation requirements and compare inventory across multiple suppliers. The package is small enough for conventional surface-mount PCB assembly while remaining compatible with standard 8-pin SOIC footprint checks.
Technically, the MK2727STR belongs to the clock-and-timing segment rather than a power-management or signal-amplifier category. Its usefulness depends on the required output frequency, tuning range, phase-noise behavior, supply requirements, reference architecture, and downstream clock tolerances. Those detailed electrical limits are not provided in the verified excerpts and must be checked against the official Renesas MK2727 datasheet before final schematic approval, timing-budget closure, or PCB release.
Typical design roles include local clock generation for embedded systems, frequency reference conditioning in communications equipment, timing support in RF systems, and synchronization in test or measurement platforms. The verified Xecor comparison describes the MK2727 family as a frequency source for 2.4 GHz and 5 GHz systems, while the manufacturer datasheet page is the authoritative source for electrical limits and application guidance.
The most important design practice is to verify the complete electrical and timing specification set rather than selecting from the distributor headline alone. Designers should confirm reference input type, output arrangement, supply voltage, tuning interface, temperature range, and pin-level truth table in the manufacturer datasheet. This page distinguishes verified facts from unavailable parameters and avoids treating distributor classifications as substitutes for engineering specifications.
This product data consolidates verified distributor listings, the official Renesas datasheet link, package information, and application context for engineers evaluating the MK2727STR. It is intended to support initial sourcing and design screening, while final qualification remains dependent on the full manufacturer datasheet and application-specific validation.

Ứng dụng tiêu biểu
MK2727STR phù hợp cho 6 Áp dụngs: Communications Clock Reference, RF Reference Generation, Embedded-System Timing, Synchronized Test Equipment, Frequency-Synthesizer Interface, Industrial Timing Control.
Communications Clock Reference
The MK2727STR is suitable for screening in communications equipment that needs a local PLL/VCXO frequency-reference function. Its verified 27 MHz nominal frequency makes it relevant to clocking and frequency-conditioning blocks where the system must derive a stable timing reference rather than rely directly on an unconditioned source. The designer should place the IC in the clock-and-timing section of the signal chain and follow the official reference layout for its reference, tuning, and decoupling connections. The primary benefit is integration of PLL and VCXO functionality in an 8-SOIC package. Phase noise, tuning range, supply voltage, and output level remain unverified in the supplied excerpts and must be checked in the Renesas datasheet before release.
Được đề xuất
RF Reference Generation
The MK2727STR can be evaluated for RF systems requiring a local frequency reference, particularly in the context of the verified MK2727-family description for 2.4 GHz and 5 GHz systems. Its PLL/VCXO architecture provides a timing function that may feed RF signal-chain blocks, while the 27 MHz nominal operating point offers a defined starting reference for system planning. The device should not be assumed to be an RF front-end component; engineers must establish its exact output, noise, and output-level specifications from the manufacturer datasheet. PCB placement should separate sensitive reference and clock routing from noisy switching stages, with grounding and return paths controlled according to the reference design.
Được đề xuất
Embedded-System Timing
The MK2727STR is applicable to embedded and control systems that require a dedicated clock-conditioning or frequency-synthesis function. The verified 27 MHz nominal frequency provides a concrete timing reference for preliminary architecture work, while the PLL and VCXO classifications support designs needing controllable frequency behavior. In a typical implementation, the IC would be placed near the system reference network and connected to the timing distribution or synthesizer section. Its compact 8-SOIC outline can simplify board planning compared with larger clock packages. However, engineers must verify startup behavior, output drive, supply requirements, tuning interface, and temperature limits before treating the device as a drop-in clock solution for an existing design.
Được đề xuất
Synchronized Test Equipment
The MK2727STR may be used in test and measurement platforms where a controlled reference clock supports synchronization, sampling, or signal-generation subsystems. Its verified PLL/VCXO classification and 27 MHz nominal frequency make it a candidate for a local timing source, provided its phase-noise and tuning specifications meet the measurement budget. The clock should be routed using short, controlled-impedance paths when driving higher-frequency nodes, with return-current continuity maintained through the ground plane. Power decoupling should follow the official datasheet recommendation rather than generic values. Because no verified output waveform, jitter, noise, or supply information is included in the supplied excerpts, laboratory characterization and datasheet review are required before selecting it for precision instrumentation.
Được đề xuất
Frequency-Synthesizer Interface
The MK2727STR can be positioned as a clock and frequency-synthesis building block in systems that require a stable reference with voltage-controlled tuning capability. Its verified product classification supports evaluating it as a VCXO-based timing source, while the 27 MHz nominal frequency provides a defined operating point for initial block diagrams. Integration requires checking the control voltage range, reference input arrangement, output configuration, and stability against the system specification. A practical implementation should reserve routing for the tuning network and isolate noisy supplies from the clock reference section. The verified excerpts do not state phase noise or frequency-span limits, so the design must not assume performance based only on the 27 MHz headline specification.
Được đề xuất
Industrial Timing Control
The MK2727STR is suitable for preliminary evaluation in industrial timing-control equipment where a PLL/VCXO reference can support deterministic clocking or synchronization. The 8-SOIC package provides a compact surface-mount form factor, and the 27 MHz nominal frequency can serve as a clear basis for initial board planning. In an industrial design, the timing reference should be isolated from switching-node noise, and the regulator used to power the clock circuit should have adequate transient response. Engineers should verify operating-temperature limits, supply tolerance, output jitter, and lifecycle status before selecting the device for long-life production equipment. The verified data confirms the component class and package, but not industrial qualification or environmental ratings.

Ghi chú thiết kế
Begin the layout from the official Renesas package drawing and pin description rather than the distributor package label alone. Keep the reference crystal or oscillator network, tuning components, and clock outputs close to their associated pins, and preserve continuous ground return beneath the device. The supplied excerpts confirm an 8-SOIC outline but do not provide the pinout, so schematic and placement must wait for the manufacturer datasheet.
Treat the MK2727STR clock path as a controlled timing network. Route clock outputs over a continuous reference plane, minimize stubs and unnecessary vias, and keep the output away from switching regulators, inductors, and high-current return paths. Because phase noise, jitter, output drive, and edge-rate values are not present in the verified excerpts, use the datasheet limits and measurement results to determine whether series damping or additional buffering is required.
Use the manufacturer-recommended supply range and decoupling arrangement before placing the IC on a production board. The verified material does not state supply voltage or current consumption, so selecting a regulator or capacitor values from generic assumptions could create incorrect operation. Verify startup, supply ripple sensitivity, and the interaction between the clock circuit and noisy system rails during schematic review.
Do not substitute MK2727STRLF for MK2727STR solely because both appear in the same family and SOIC comparison. Suffix changes may affect frequency, temperature, package, or qualification, and the supplied cross-reference excerpt does not prove pin-to-pin equivalence. Validate the complete ordering code, pinout, electrical limits, and lifecycle status before approving a replacement.
