MK2703BSLF - 27MHz PLL Clock Synthesizer | Renesas
料号： MK2703BSLF ✗ 停产MK2703BSLF 概述
A PLL clock synthesizer is a clock and timing integrated circuit that uses phase-locked-loop technology to generate one or more stable timing signals from an external crystal or clock source. Within the semiconductor hierarchy, it belongs to the PLL and frequency-synthesizer family, combining an oscillator reference with feedback and control circuitry. The MK2703BSLF can therefore consolidate oscillator and PLL functions that might otherwise be implemented separately.
The device offers a 27 MHz reference input, selectable audio-clock generation, buffered clock outputs, CMOS compatibility, and a surface-mount SOIC-8 package. Its low-cost positioning and low-jitter PLL architecture are significant for consumer multimedia equipment, where a stable reference can be distributed to audio-processing, decoding, control, and communications blocks without implementing a complete timing subsystem on the motherboard.
According to the Renesas MK2703B datasheet, the device uses patented analog PLL techniques with a 27 MHz crystal or clock input. The resulting buffered reference clock and selectable audio clock are intended to simplify clock distribution in set-top boxes and multimedia systems. The manufacturer identifies MK2703BSLF as a RoHS-compliant SOIC-8 device, although detailed operating-temperature, output-jitter, output-frequency, and load-capacitance limits are not included in the supplied search data.
Typical uses include set-top box main boards, multimedia appliance clock trees, audio codec clocking, digital media decoders, and compact consumer equipment requiring a dedicated reference and audio-clock source. Its SOIC-8 surface-mount package supports conventional reflow assembly and makes the device suitable for cost-sensitive mixed-signal and digital boards where a larger BGA or QFN clock generator would be unnecessary.
Designers should verify the exact output frequencies, crystal load capacitance, startup time, jitter limits, decoupling requirements, and output-drive configuration against the current Renesas datasheet before release. PCB layout should keep the oscillator loop compact, provide a clean supply and ground connection, and avoid routing clock outputs through long, parallel-coupled traces where unnecessary.
This product page consolidates manufacturer information, distributor pricing, verified compliance details, replacement evidence, and practical engineering guidance. It distinguishes verified facts from parameters still requiring confirmation, helping engineers source MK2703BSLF and evaluate drop-in alternatives without relying on unsupported assumptions.

典型应用
MK2703BSLF 适用于 6 应用s: Set-Top Box Clock Tree, Multimedia Reference Clock, Audio Codec Clocking, Digital Media Decoder, Consumer Network Appliance, IoT Gateway Control Board.
Set-Top Box Clock Tree
The MK2703BSLF fits a set-top box clock tree because it combines a 27 MHz crystal or clock input with a buffered reference output in a compact 8-pin SOIC package. According to the Renesas MK2703B datasheet, this low-cost, low-jitter PLL synthesizer is specifically intended for set-top box systems. Placing it near the source oscillator can provide a stable distributed reference while reducing discrete oscillator and PLL circuitry. The 3.13 V to 5.5 V supply range suits 5 V CMOS environments, although the designer must confirm the exact output configuration and timing limits from the current datasheet.
推荐
Multimedia Reference Clock
MK2703BSLF is suitable for multimedia systems that need a centrally generated reference clock. Its analog PLL accepts a 27 MHz crystal or clock input and produces a buffered reference clock, allowing several logic blocks to share one timing source. This can simplify board partitioning and reduce the number of independent oscillator arrangements. The device's 8-SOIC package supports surface-mount assembly, while its CMOS interface and 3.13 V to 5.5 V operating range align with conventional embedded multimedia hardware. Verify jitter, startup behavior, and output loading before finalizing a high-volume design.
推荐
Audio Codec Clocking
The MK2703BSLF can support the audio-clock requirement of a multimedia system because the Renesas MK2703B family provides a selectable audio clock in addition to a buffered reference. Its low-jitter PLL architecture is relevant when audio converters, decoders, or processors require a repeatable timing reference. The 27 MHz input provides a defined foundation for the PLL, and the 8-pin SOIC footprint leaves board space for the surrounding passive network and decoupling. Exact supported audio frequencies, output drive, and jitter limits are not included in the supplied data and must be confirmed against the manufacturer datasheet.
推荐
Digital Media Decoder
MK2703BSLF is appropriate for a digital media decoder that requires a shared reference clock across audio, video-control, memory-interface, and communications blocks. Consolidating oscillator and PLL functions into one low-cost 8-SOIC device can reduce component count and simplify board validation. The CMOS bus interface and 3.13 V to 5.5 V supply range fit conventional 5 V embedded logic. Layout remains important: the crystal or clock input should be short, the supply should be locally decoupled, and clock traces should be routed away from high-slew-rate data paths to minimize coupling.
推荐
Consumer Network Appliance
The MK2703BSLF can support timing distribution in a consumer network appliance, including a router, smart-home controller, or multimedia endpoint with multiple clocked subsystems. A buffered reference generated from a 27 MHz source can provide a common timing reference to communications and processing blocks while the selectable audio output serves mixed-signal sections. Its SOIC-8 package is easy to assemble with conventional leaded or no-lead land patterns and is appropriate for cost-sensitive boards. Verify output frequency options and any Ethernet-derived timing requirements before using it in a standards-sensitive interface.
推荐
IoT Gateway Control Board
MK2703BSLF is useful in an IoT gateway when several embedded blocks need a stable local reference and an audio-capable multimedia subsystem is present. The low-cost 8-pin SOIC implementation can provide a dedicated clock synthesizer without occupying a high-pin-count FPGA or system-on-chip. Its 3.13 V to 5.5 V operating range permits operation across common low-voltage CMOS rails. Engineering care should be applied to grounding, supply bypass, crystal placement, and clock-output fanout, especially where long PCB traces could increase EMI coupling or degrade signal integrity.

设计说明
Place the MK2703BSLF close to the 27 MHz crystal or clock source and keep the oscillator loop physically compact. Route the crystal pins directly to the device where practical, maintain a solid uninterrupted ground plane beneath the oscillator area, and avoid running digital, switch-mode, or high-current traces beneath the crystal network. The supplied sources do not specify a required PCB layout pattern, so the current Renesas MK2703B datasheet layout guidance should take precedence.
Decouple the 3.13 V to 5.5 V supply close to the device and preserve a continuous return path to the ground reference. The supplied data does not state the recommended capacitance or ESR, so these values must be taken from the manufacturer datasheet rather than estimated. Because a PLL clock synthesizer can be sensitive to supply disturbance, evaluate the board's switching-supply ripple and startup sequence using the datasheet's recommended test conditions.
Route reference and audio-clock outputs as short, controlled-impedance traces where their frequency content requires it. Avoid branching long clock nets unnecessarily, provide the intended termination or load, and keep clock traces away from switching nodes and high-current return paths. Confirm output drive strength, allowable loading, jitter contribution, and rise/fall behavior in the current datasheet because these values are not available in the supplied search snippets.
合规信息
The supplied FindIC record explicitly identifies MK2703BSLF as RoHS compliant. No verified REACH, lead-free, halogen-free, conflict-minerals, or automotive-qualification statements were provided. AEC-Q100 is marked not_applicable because this is a consumer-oriented clock and timing IC rather than an automotive-qualified device.
