SI5338M-B05075-GM

Overview

The SI5338M-B05075-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 0 ppm precision. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA. Key electrical parameters include a maximum input frequency of 710 MHz, a typical phase jitter of 0.7 ps RMS, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm accuracy.
• Supports flexible input references including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Features low phase jitter of 0.7 ps RMS typ and glitchless frequency adjustments via independent increment/decrement features.
• Configurable spread spectrum (SSC) allows any frequency from 5 to 350 MHz with modulation rates from 33 to 63 kHz.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems.
• Ethernet switch/router and 1 GbE/10 GbE networking equipment.
• Processor and FPGA clocking solutions.
• Broadcast video/audio timing infrastructure.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm factory programming configurations. Ensure compatibility with I2C/SMBus interface requirements for system integration. Confirm package type and moisture sensitivity levels prior to PCB assembly planning.

Selection Notes

Select this component when independent frequency synthesis across four outputs is required without multiple crystal oscillators. Ensure the target application supports the specified voltage ranges (1.8 V, 2.5 V, or 3.3 V) and fits within the thermal constraints of the QFN-24 package. Validate that the desired output formats (LVPECL, LVDS, HCSL, etc.) align with the driver capabilities.

Part Context

This part belongs to the Si5338 family of high-performance, low-jitter clock generators. The series is designed to replace discrete oscillators and function as frequency translators in complex digital systems. It shares common architectural features such as the MultiSynth architecture and I2C programmability across the product line.

Replacement Considerations

Consult official Skyworks Solutions substitution guides for verified compatible alternatives. Do not assume functional equivalence with other clock generators based solely on pin count or package dimensions.
