SI5338N-B05878-GMR

Overview

The SI5338N-B05878-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is managed via an I²C/SMBus interface, allowing for flexible input references including crystals, CMOS, and differential signals.

Feature Summary

• MultiSynth™ technology enables zero ppm precision synthesis on four independent outputs
• Supports LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL output formats
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input options: external crystal (8-30 MHz), CMOS (5-200 MHz), and differential (5-710 MHz)

Applications

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

Procurement Notes

Verify the specific ordering suffix B05878 against the manufacturer's current datasheet to confirm factory-programmed frequency and format configurations. Ensure compatibility with the required I²C pull-up voltage levels if operating below 2.5 V. Confirm package type matches the 24-QFN specification.

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.) match the application requirements. Check that the input reference frequency falls within the supported ranges for the chosen configuration mode.

Part Context

This part belongs to the Si5338 family of I²C-programmable clock generators. The 'N' in the part number typically denotes a specific output configuration variant within the series, while 'GMR' indicates tape and reel packaging. It replaces discrete oscillators in complex digital systems.

Replacement Considerations

Direct pin-to-pin replacements may include other Si5338 variants with different factory programming. Verify that alternative parts support the same output count and signal formats. Software reprogramming tools like ClockBuilder Pro may be required for functional equivalence.
