SI4134T-BM - 1.99 GHz PLL Frequency Synthesizer | Silicon Labs
MPN: SI4134T-BM ✗ Cuối đờiSI4134T-BM Tóm tắt
A frequency synthesizer is a clock-and-timing IC that uses a phase-locked loop to generate, divide, or multiply a reference frequency into a stable output clock. Within the broader semiconductor hierarchy, it belongs to the clock generator and PLL family, operating as a timing-management IC within communications and electronic-control systems. Its internal PLL enables frequency generation from a stable reference source, making it useful where a system requires precise, repeatable clocking rather than a free-running oscillator alone.
Key verified features include a maximum frequency of 1.99 GHz, a 2.7 V to 3 V operating supply range, a clock input, a clock output, PLL operation, a 1:2 input-to-output ratio, and a differential output arrangement identified as No input and Yes output in the supplied distributor data. The 32-VFQFN exposed-pad package is designed for surface-mount assembly and supports compact implementation in RF and baseband circuits. The listed operating-temperature range is -20 °C to +85 °C.
The SI4134T-BM is intended for RF and baseband circuit applications, data converters, transceivers, and other high-speed systems that require synthesized clocks. Its relatively low 2.7 V to 3 V supply range makes it suitable for systems built around low-voltage RF and mixed-signal architectures. The 1:2 ratio provides a straightforward multiplication function when the system reference is arranged for that relationship.
When designing around this part, verify the complete pinout, reference-clock requirements, loop-filter component values, output-routing options, and exposed-pad land pattern against the manufacturer datasheet. Because the supplied web data does not include the full pin assignments, reference frequency range, output drive, phase-noise limits, or recommended decoupling details, those values remain marked as data-needed rather than inferred. The exposed pad should be connected according to the manufacturer’s thermal and layout guidance.

Ứng dụng tiêu biểu
SI4134T-BM phù hợp cho 6 Áp dụngs: RF Clock Generation, RF and Baseband Circuit Timing, Data Converter Clocking, Transceiver Reference Clocking, Test and Measurement Instrumentation, Industrial Frequency Control.
RF Clock Generation
The SI4134T-BM fits RF clock-generation blocks that require a synthesized signal from a stable reference. Its PLL architecture, 1.99 GHz maximum frequency, clock input, differential clock output, and 1:2 input-to-output ratio support systems where the reference frequency is arranged for multiplication. The 2.7 V to 3 V supply range also aligns with low-voltage RF front ends. Engineers should verify phase-noise, output-drive, reference-range, and loop-filter requirements in the manufacturer datasheet before finalizing the design.
Được đề xuất
RF and Baseband Circuit Timing
The SI4134T-BM can supply a stable synthesized clock to coordinated RF and baseband circuits, helping keep related signal paths synchronized. Its single PLL frequency-synthesizer circuit and differential clock output are suited to systems using a common reference distribution scheme. The 1:2 ratio provides a direct multiplication relationship in suitable reference plans. Because the supplied information does not include full pin functions or output specifications, engineers should confirm routing, termination, impedance, and loop stability against the latest datasheet.
Được đề xuất
Data Converter Clocking
The SI4134T-BM is relevant to data-converter clocking where the system needs a multiplied, repeatable reference clock. The verified 1:2 input-to-output ratio can simplify reference planning, while the differential clock output can reduce sensitivity to common-mode noise when used with a properly designed interface. Its 1.99 GHz maximum frequency provides useful headroom for intermediate clock rates. Sampling accuracy, aperture jitter, output amplitude, and allowable converter clock range must still be checked before substitution into an existing design.
Được đề xuất
Transceiver Reference Clocking
The SI4134T-BM can support reference-clock generation for RF transceivers operating from a 2.7 V to 3 V supply domain. Its PLL-based clock output, maximum frequency of 1.99 GHz, and differential output arrangement are useful when multiple transceiver lanes need a coherent timing source. Integration is practical in a compact 5 mm by 5 mm 32-VFQFN footprint, although the exposed pad requires the land pattern and thermal treatment specified by the manufacturer. Verify carrier frequency, reference jitter, and output topology before use.
Được đề xuất
Test and Measurement Instrumentation
The SI4134T-BM is suitable for compact test and measurement equipment that requires an internally generated clock rather than relying entirely on an external reference. The PLL architecture allows the instrument to derive a higher output frequency from a lower reference, and the 1:2 ratio provides a useful integer multiplication relationship. Its surface-mount 32-VFQFN package supports dense instrument designs. Designers should evaluate phase-noise behavior, reference-capture range, calibration requirements, and warm-up characteristics using the manufacturer’s test data.
Được đề xuất
Industrial Frequency Control
The SI4134T-BM can provide deterministic clock generation in industrial and embedded control systems that coordinate sampling, conversion, or communication functions. Its single-circuit PLL implementation, 1:2 ratio, and defined -20 °C to +85 °C operating range make it a candidate for compact industrial equipment. The 32-VFQFN package helps minimize board area while the exposed pad supports thermal management when required. Before designing it in, verify clock-jitter limits, power-supply sensitivity, startup behavior, and the exact package pinout.

Ghi chú thiết kế
Use the manufacturer’s exact 32-VFQFN exposed-pad land pattern, including pad geometry, solder-mask definition, and thermal-via recommendations. Place the reference and clock connections according to the recommended high-frequency layout, minimize loop area, and provide a continuous ground reference. Do not infer pin assignments from a generic QFN-32 drawing because the verified snippets do not identify the individual SI4134T-BM pins.
Design the 2.7 V to 3 V supply rail with low impedance and place the manufacturer-specified bypass capacitors close to the relevant supply and ground pins. The supplied data confirms the voltage range but does not provide capacitor values or current limits, so those details must be taken from the manufacturer datasheet. Verify startup sequencing and supply ripple tolerance for PLL lock performance.
Do not treat a same-package family member as a drop-in replacement without checking reference frequency, programmable range, pin multiplexing, control logic, differential-output polarity, and loop-filter requirements. The verified data confirms a 1:2 ratio for SI4134T-BM and reports package consistency for SI4134T-GM, but it does not provide enough information to approve an unconditional substitution.
Thông tin tuân thủ
The supplied comparison data describes the SI4134T-BM as lead-free and QFN-32, but it does not provide RoHS, REACH, halogen-free, or conflict-minerals declarations.
