SI4136-BM 概述
A frequency synthesizer is a clock-and-timing device that generates, multiplies, divides, and locks a reference signal to a selected output frequency. The SI4136 belongs to the PLL frequency-synthesizer and RF-synthesizer hierarchy, where a phase-locked loop steers an oscillator to maintain a controlled relationship between a stable reference and an RF output. This makes the device relevant to wireless transceivers, RF modems, frequency-agile communications equipment, and embedded RF systems rather than ordinary low-frequency clock distribution.
The SI4136-BM combines three integrated VCOs with programmable dividers and phase detectors. This architecture allows the synthesizer to cover multiple RF conversion paths while centralizing frequency planning in a serial-programmable device. The verified component data identifies PLL operation, crystal input, clock output, one circuit, and support for divider and multiplier functions. The three-wire serial programming interface is important because it reduces the number of discrete control connections required by the system.
The SI4136-BM is specified for a maximum frequency of 2.5 GHz and an operating supply range of 2.7 V to 3.6 V, making it suitable for compact RF systems whose supply architecture is already designed around low-voltage semiconductor rails. Its exposed pad provides a thermal and electrical connection to the PCB, but the required thermal-management details and exact pad-layout guidance must be taken from the manufacturer datasheet before layout release. The 28-VFQFN footprint is a surface-mount package intended for manufacturing reflow and automated assembly.
Typical applications include wireless communication modules, RF front-end supporting ICs, IF/RF conversion chains, and industrial or consumer products requiring programmable frequency generation. In these systems, the synthesizer establishes a stable RF or intermediate-frequency reference while the surrounding transceiver handles signal mixing, modulation, filtering, and power amplification. Integration can reduce board area and assembly complexity, although system designers must still verify reference-noise requirements, loop-filter settings, startup behavior, and regulatory output requirements.
Designers should preserve the exposed-pad copper connection, place supporting components according to the manufacturer’s reference layout, and keep sensitive RF and reference traces away from noisy switching nodes. Because the verified data does not provide the complete pin-level electrical table, pin names, oscillator tuning range, reference frequency, divider ratios, output characteristics, or recommended loop-filter values, those parameters require confirmation in the official datasheet. This page combines the verified product identity, package, supply, frequency, and sourcing information with practical design guidance without filling unavailable values with assumptions.
This product-data summary distinguishes SI4136-BM from ordinary fixed-frequency oscillators by emphasizing its integrated VCOs, dividers, phase detectors, loop filters, and serial programming. For procurement, verify current manufacturer identity and lifecycle status with an authorized distributor because search results reference both Silicon Labs and Skyworks Solutions, and confirm the exact package, temperature range, and electrical configuration against the latest manufacturer documentation.

典型应用
SI4136-BM 适用于 6 应用s: Wireless Transceiver RF Synthesizer, RF Front-End Frequency Conversion, Programmable IF Synthesizer, Industrial RF Control System, RF Test and Measurement Instrument, Wireless Communication Module.
Wireless Transceiver RF Synthesizer
SI4136-BM fits a wireless transceiver that needs programmable RF or IF conversion references up to 2.5 GHz. Its three VCOs, phase detectors, and dividers provide the core frequency-synthesis functions required when a transceiver must switch between channels or support multiple conversion paths. The three-wire serial interface allows a host controller to configure divider and powerdown settings. Designers should still validate reference-noise performance, loop stability, output drive, and regulatory requirements against the manufacturer’s complete electrical tables before release.
推荐
RF Front-End Frequency Conversion
SI4136-BM can provide a programmable local-oscillator reference for an RF front end that mixes incoming or outgoing signals into IF or processing bands. Its maximum frequency of 2.5 GHz and integrated VCO structure make it appropriate for systems whose RF architecture requires more than a fixed-frequency clock. The synthesizer must be paired with correct impedance-controlled routing, stable reference routing, and validated loop-filter or programming settings. The exposed-pad connection should follow the manufacturer’s thermal and assembly drawing.
推荐
Programmable IF Synthesizer
The SI4136-BM is applicable to IF synthesis in wireless equipment where a receiver or transmitter needs a controlled intermediate-frequency reference. Integrated reference and VCO dividers, phase detectors, and loop filters provide a complete synthesis block rather than requiring separate oscillator, divider, and detector components. The verified operating range of 2.7 V to 3.6 V supports low-voltage RF system architectures. Exact IF frequency range, resolution, output power, and lock-time requirements must be confirmed from the full manufacturer datasheet.
推荐
Industrial RF Control System
SI4136-BM can support an industrial RF control system that requires a programmable reference across a changing operating condition. Its three VCOs and serial-programmable divider settings offer flexibility for systems that select different RF or IF outputs through firmware. The 2.5 GHz maximum frequency and 28-VFQFN package make the device suitable for compact RF modules, while the -40°C to +85°C operating range supports industrial-temperature design requirements. Validate EMC, enclosure grounding, thermal performance, and long-term calibration behavior in the final system.
推荐
RF Test and Measurement Instrument
SI4136-BM may be used in an RF test instrument that needs a programmable local oscillator or IF reference for signal generation or analysis. The three internal VCOs and dividers can support multiple synthesis paths, while the serial interface simplifies configuration by firmware. In an instrument, reference spurs, phase noise, lock behavior, output isolation, and calibration accuracy are often more important than raw integration alone. Those parameters are not available in the supplied verified excerpts and must be measured or obtained from the complete datasheet.
推荐
Wireless Communication Module
SI4136-BM is a practical fit for a wireless communication module that requires an integrated frequency synthesizer rather than a collection of discrete RF timing components. The monolithic integration of three VCOs, loop filters, dividers, and phase detectors can reduce board-level frequency-generation complexity. A module designer should account for the 2.7 V to 3.6 V supply range, exposed-pad thermal connection, reference routing, and RF layout separation. The final design must verify channel spacing, frequency accuracy, spur performance, and regulatory compliance for the deployed wireless standard.

设计说明
Use the manufacturer’s exact 28-VFQFN land pattern and preserve the exposed-pad electrical and thermal connection. The verified data confirms an exposed-pad package but does not provide pad dimensions, mask rules, or via spacing, so the PCB footprint must not be inferred from the package name. Place input, supply, and decoupling connections according to the official reference layout before signal-integrity or RF routing begins.
Keep the reference input, synthesizer control lines, and RF output paths short and controlled, and separate sensitive timing routes from switching-power nodes and high-current return paths. Because the device supports RF synthesis up to 2.5 GHz, trace geometry, return-plane continuity, impedance targets, and enclosure or chassis grounding can affect system behavior. The supplied data does not specify output impedance or layout values, so validate the final stackup and RF environment with the manufacturer’s guidance.
Design the low-voltage supply around the verified 2.7 V to 3.6 V operating range and verify startup, sequencing, and transient response in the complete RF module. The exposed pad should be connected to the intended supply or ground network only as directed by the manufacturer’s pin table. Do not invent bypass values or current limits; obtain them from the complete datasheet and measure in-circuit behavior for the selected reference and output-frequency range.
A distributor cross-reference listing does not by itself prove that SI4136-F-BM, SI4136-F-GM, or another related suffix is a true drop-in replacement. Before substituting, compare package drawings, every numbered pin, supply limits, serial protocol, register behavior, divider ranges, VCO coverage, output characteristics, and lifecycle status. The verified excerpts do not provide enough detail to certify any related part as a production replacement.
合规信息
The supplied verified results identify the component, package, supply range, temperature range, and sourcing information but do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-mineral status. Compliance must be confirmed from current manufacturer documentation or authorized distributor records.
