SI5338A-B02426-GMR

Overview

The SI5338A-B02426-GMR is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports input frequencies up to 710 MHz and generates outputs ranging from 0.16 MHz to 710 MHz depending on the selected format (LVPECL, LVDS, CML, HCSL, CMOS, SSTL, or HSTL). Key electrical parameters include a typical core supply current of 45 mA, a maximum operating temperature of +85 °C, and a typical RMS jitter of 0.7 ps. It operates on a single core supply voltage of 1.8 V, 2.5 V, or 3.3 V.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with true zero ppm accuracy.
• Low phase jitter performance with a typical RMS value of 0.7 ps for GbE applications.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (up to 710 MHz).
• Independent output voltage configuration per driver supporting 1.5 V, 1.8 V, 2.5 V, or 3.3 V levels.

Applications

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

Procurement Notes

Verify the specific ordering suffix B02426 against the manufacturer's official documentation to confirm the pre-programmed frequency and output configuration. Ensure compatibility with I2C/SMBus interface requirements and check for moisture sensitivity handling procedures during assembly.

Selection Notes

Select this component when low jitter (<1 ps RMS) and high flexibility in output formats are required. Verify that the target application supports the QFN-24 package dimensions and that the power supply rails match the 1.8 V, 2.5 V, or 3.3 V core voltage specifications.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'A' designation typically indicates the highest performance tier within the series, supporting frequencies up to 710 MHz. The 'GMR' suffix denotes a tape-and-reel packaging format suitable for automated surface-mount assembly.

Replacement Considerations

Consult the official Skyworks replacement guide for verified substitutes. Generic cross-model replacements may not support the same jitter performance or output format flexibility.
