SI5330F-B00216-GM - 1:8 LVCMOS Clock Fanout Buffer | Skyworks
MPN: SI5330F-B00216-GM ✓ Hoạt độngSI5330F-B00216-GM Tóm tắt
A clock fanout buffer is a timing-IC category that distributes a single reference clock to multiple loads while preserving edge fidelity. In the system hierarchy, it sits below the clock generator/synthesizer and above the load-side receivers: clock generator -> clock buffer -> downstream logic (FPGA, ASIC, memory, PHY). By replacing ad-hoc fanout trees built from discrete gates or zero-delay buffers, fanout ICs reduce additive jitter and pin-to-pin skew across the board.
Key specifications include 50 ps typical additive jitter, less than 100 ps output-to-output skew, less than 150 ps part-to-part skew, and CMOS-compatible inputs and outputs with on-chip termination. The exposed pad provides a low-thermal-resistance path for high-frequency operation, while per-output enable pins (SDA_SCL, OE) support individual clock gating and power-sequencing schemes. The device is optimized for high-performance PCB clock distribution where deterministic timing and clean signal edges are required.
Architecturally, the SI5330F-B00216-GM uses a non-PLL, fixed-logic fanout core that minimizes cycle-to-cycle variation and avoids the spurious outputs typical of PLL-based buffers. The input accepts LVCMOS, LVDS, LVPECL, HCSL, or SSTL clock sources, and each output can be independently powered to support mixed-voltage rails (1.8 V outputs from a 3.3 V supply, etc.). This combination of architecture and I/O flexibility simplifies board design while maintaining sub-100 ps skew.
Typical applications include clock distribution on FPGA- and ASIC-based line cards, server and storage backplane clock trees, networking switches and routers, communications infrastructure, and any PCB requiring multiple copies of a low-jitter reference clock. It is well suited to fan-out of a backplane-derived clock to multiple PHY or transceiver devices.
When designing with this part, place input and output decoupling capacitors within 100 mils of their respective supply pins and stitch the exposed pad with at least 9 thermal vias to the internal ground plane. Source-terminate long clock traces to limit reflections, and avoid routing outputs parallel to high-speed data signals to prevent crosstalk into timing edges.

Ứng dụng tiêu biểu
SI5330F-B00216-GM phù hợp cho 6 Áp dụngs: FPGA Clock Distribution, Networking Switch and Router Clock Tree, Server and Storage Backplane Clocking, Telecom and Communications Infrastructure, Industrial Automation and Factory Backplane, Test and Measurement Instrumentation.
FPGA Clock Distribution
The SI5330F-B00216-GM is ideal for FPGA clock distribution because it delivers eight low-jitter LVCMOS copies of a single reference clock with sub-100 ps output-to-output skew, preserving deterministic timing across multiple FPGA clock pins and companion transceivers. Each output can be individually enabled for power sequencing of FPGA banks and PCIe/SerDes lanes, while the 1.8 V / 2.5 V / 3.3 V mixed-voltage support lets one buffer drive FPGAs running at 1.8 V core clocks and 3.3 V I/O clocks from a single 2.5 V reference. Source: Si5330 datasheet recommended applications and Skyworks fanout buffer family.

Networking Switch and Router Clock Tree
In networking line cards, the SI5330F-B00216-GM fans out a single recovered clock from the PHY or backplane to multiple ASICs, packet processors, and SerDes PHYs while maintaining tight skew budgets required for Ethernet, SONET/SDH, and PTP timing. Its 200 MHz maximum output frequency covers 156.25 MHz telecom references and 161.13 MHz OTN clocks, and the 24-QFN exposed-pad footprint eases placement near the switch ASIC clock input. Compared with discrete zero-delay buffers, the Si5330F keeps additive jitter at 0.15 ps typical, which is essential for meeting IEEE 802.3 jitter masks.
Được đề xuất
Server and Storage Backplane Clocking
The SI5330F-B00216-GM serves as the central clock fanout in server and storage backplanes, distributing one backplane reference to multiple SAS/SATA controllers, DDR memory buffers, and BMC/MCU clock inputs. Its 1.71 V to 3.63 V supply range supports both legacy 3.3 V BMC rails and modern 1.8 V DDR4 clock trees from a single buffer, while the exposed pad ensures thermal stability in dense 1U/2U chassis. The Si5330F's non-PLL architecture avoids PLL locking transients during power-up, which is critical for deterministic server boot.

Telecom and Communications Infrastructure
Telecom infrastructure uses the SI5330F-B00216-GM to fan out a Stratum-3/3E reference or GPS-derived 1PPS-conditioned clock across multiple line cards while meeting ITU-T G.8262 wander and jitter masks. The device's sub-100 ps output-to-output skew ensures deterministic phase alignment between transmit and receive paths in OTU/STM framer ASICs, and the 24-QFN package supports reflow profiles standard in carrier-grade PCB assembly. Per the Si5330 datasheet, the buffer is explicitly characterized for these mixed-frequency, mixed-voltage telecom fanout scenarios.

Industrial Automation and Factory Backplane
In industrial automation, the SI5330F-B00216-GM distributes a single PROFIBUS, EtherCAT, or TSN reference clock across PLC backplanes and motor-drive controller cards with the -40 C to +85 C industrial temperature range. Its LVCMOS output levels integrate directly with industrial FPGA and MCU clock inputs, while the 1:8 fanout lets one buffer replace four discrete gates and reduce BOM. Industrial users benefit from the Si5330F's robust ESD and the exposed-pad thermal path required for sealed, fan-less enclosures.
Được đề xuất
Test and Measurement Instrumentation
Test and measurement instruments leverage the SI5330F-B00216-GM to fan out a single low-noise reference (often a TCXO or OCXO) to multiple ADC/DAC sample clocks, FPGA clock inputs, and trigger distribution paths. The 0.15 ps additive jitter specification preserves the SNR of high-resolution ADCs downstream, while the 1:8 ratio allows a single reference to drive a full multi-channel oscilloscope or signal analyzer board. The exposed-pad package supports the dense layouts common in compact benchtop instruments.

Ghi chú thiết kế
Place 0.1 uF ceramic decoupling capacitors within 100 mils of each VDDx output supply pin and the central VDD core supply pin. Stitch the central exposed pad with at least 9 thermal vias (12 mil diameter, 0.5 oz plating) to an internal ground plane to achieve the datasheet thermal resistance. Source-terminate each output trace with a series resistor (typically 22-33 ohm) located within 200 mils of the output pin to dampen reflections on long clock traces.
Keep output traces on a dedicated clock layer with a continuous ground plane below, and avoid routing CLK_OUT traces parallel to high-speed data signals (PCIe, SATA, DDR) for more than 100 mils to prevent crosstalk into timing edges. Maintain 3W spacing (3x dielectric height) between adjacent clock traces to limit coupling. When driving a differential receiver, AC-couple or DC-bias the LVCMOS outputs according to the receiver's common-mode requirements - the Si5330 outputs are LVCMOS, not LVDS/LVPECL.
Do not leave any VDDx output supply pin floating - each of the eight CLK_OUT outputs has its own VDDx pin that must be powered even if the output is unused, otherwise output leakage and supply noise will degrade jitter. Verify the input clock meets the 5 MHz minimum frequency (per the Skyworks Si5330 datasheet recommended operating conditions); frequencies below this will not lock and the outputs may exhibit undefined behavior. Avoid hot-plugging VDD with input clocks already present - the datasheet specifies a power-up sequence for clean startup.
