SI5338N-B06022-GMR

Overview

The SI5338N-B06022-GMR is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero ppm frequency accuracy using MultiSynth technology. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. Maximum input frequency reaches 710 MHz via differential inputs, while outputs support up to 710 MHz for LVDS/LVPECL/CML and 200 MHz for CMOS. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with typical current consumption of 45 mA.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential (5–710 MHz).
• Low phase jitter performance with 0.7 ps RMS typical random jitter.
• Programmable via I2C/SMBus interface with glitchless frequency adjustment in 1 ppm steps.

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 B06022 against the manufacturer's official documentation to confirm pre-programmed register settings. Ensure the I2C pull-up voltage compatibility matches the system bus requirements, particularly if operating below 2.5 V. Confirm package integrity for the 24-QFN form factor during inspection.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source. Verify that the target output signal formats (LVDS, LVPECL, etc.) align with the driver capabilities. Check that the input reference frequency falls within the supported ranges for the chosen input pin configuration.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and frequency translators. The N suffix typically denotes a specific factory-programmed configuration variant within the broader Si5338 product line.

Replacement Considerations

Direct replacements must match the 24-QFN package and I2C interface. Verify functional equivalence regarding output count and maximum frequency limits. Consult the manufacturer's cross-reference list for confirmed substitutes with identical electrical characteristics.
