SI5338N-B06177-GM

Overview

The SI5338N-B06177-GM is a programmable quad clock generator 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, achieving zero ppm precision. The device operates from 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 performed via an I2C/SMBus interface, allowing flexible input references including crystals, CMOS, and differential signals.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm accuracy
• 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 Gen 3 SRNS compliant 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 pinout compatibility and factory programming settings. Ensure the I2C pull-up voltage aligns with the system bus requirements, as register adjustments may be necessary for voltages below 2.5 V.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single package. Ensure the target output format (LVDS, LVPECL, etc.) matches the receiver specifications. Verify that the input reference source falls within the supported frequency ranges for the desired configuration.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete oscillators and frequency translators in high-performance digital systems. The N suffix typically denotes a specific factory-programmed frequency set and output configuration defined by Skyworks Solutions.

Replacement Considerations

Direct replacements must match the 24-QFN package and support similar output counts and frequencies. Verify that alternative devices offer comparable jitter performance and I2C configurability if field reprogramming is required.
