SI5338A-B04361-GMR

Overview

The SI5338A-B04361-GMR is a programmable clock generator utilizing MultiSynth technology to synthesize independent frequencies on four output drivers. It supports differential and single-ended outputs with formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply and accepts flexible inputs such as external crystals (8–30 MHz), CMOS (up to 200 MHz), or differential signals (up to 710 MHz). Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum output frequency of 710 MHz for differential pairs, and operation within a temperature range of –40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with zero ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 Common Clock standards.
• Highly configurable output drivers supporting up to four differential outputs, eight single-ended outputs, or mixed configurations.
• Independent frequency increment/decrement feature allows glitchless adjustments in 1 ppm steps via I²C/SMBus interface.

Applications

• PCIe Gen 1/2/3/4 systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type, tape-and-reel quantity, and RoHS compliance status. Ensure that the required output frequencies and signal formats are supported by the pre-programmed configuration associated with this part number before procurement.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single IC. Verify that the target application supports the available input reference options, such as external crystals or differential clocks. Confirm that the output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements for each driver.

Part Context

This part belongs to the Si5338 family of quad clock generators produced by Skyworks Solutions. The 'A' designation typically indicates a specific performance grade or output capability variant within the series, while the numeric suffix denotes the factory-programmed frequency plan. The '-GMR' suffix identifies the reel packaging format.

Replacement Considerations

Direct replacements must be verified against the official Skyworks cross-reference list. Substitutes should maintain compatibility with the I²C programming interface and support the same output formats and frequency ranges if pin-to-pin replacement is required.
