SI5338A-B04362-GMR

Overview

The SI5338A-B04362-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. It operates within a core supply range of 1.71 V to 3.63 V and supports input frequencies up to 710 MHz. The device features low phase jitter of 0.7 ps RMS typical, configurable output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, and allows independent voltage selection per driver. Encased in a 4 x 4 mm QFN-24 package, it enables glitchless frequency adjustments and spread spectrum generation.

Feature Summary

• MultiSynth™ technology for independent, any-frequency synthesis on four differential output drivers
• Low phase jitter of 0.7 ps RMS typical across all outputs
• Flexible input reference supporting external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz
• Independent output voltage configuration (1.5, 1.8, 2.5, or 3.3 V) per driver

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and factory programming settings. Confirm RoHS compliance status and moisture sensitivity level requirements prior to PCB assembly. Ensure I2C pull-up voltages align with the supported range of 1.71 V to 3.63 V for proper interface operation.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single source with high precision. Ensure the required output signal formats (LVPECL, LVDS, HCSL, etc.) are supported by the available drivers. Verify that the input reference frequency falls within the specified ranges for crystal, CMOS, or differential inputs. Consider thermal resistance characteristics if operating at maximum load conditions.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and frequency translators in compact designs. The device integrates PLL and MultiSynth stages to provide flexible clock distribution solutions for high-speed digital interfaces.

Replacement Considerations

Consult official Skyworks substitution guides for verified alternatives. Generic clock generators may not support the same MultiSynth architecture or jitter performance specifications.
