SI5338N-B05026-GM

Overview

The Skyworks SI5338N-B05026-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision. The device supports flexible input references, including differential inputs up to 710 MHz and single-ended CMOS inputs up to 200 MHz. Output formats include LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, with frequencies ranging from 0.16 MHz to 710 MHz depending on the format. Key electrical parameters include a typical core supply current of 45 mA, a maximum operating temperature of +85 °C, and a typical phase jitter of 0.7 ps RMS.

Feature Summary

• Low phase jitter of 0.7 ps RMS typical
• Independent frequency increment/decrement for glitchless adjustments in 1 ppm steps
• Highly configurable spread spectrum (SSC) with modulation rates from 33 to 63 kHz
• Supports external feedback mode for zero-delay operation

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout configuration and factory programming settings. Ensure compatibility with I2C/SMBus interface voltage levels (1.71 V to 3.63 V) during integration. Confirm that the required output formats and frequencies fall within the specified operational limits for the selected package variant.

Selection Notes

Select this component when independent, any-frequency synthesis is required for multiple clock domains. The device supports up to four differential outputs or eight single-ended outputs. Consider the power supply requirements (1.8 V, 2.5 V, or 3.3 V) and the need for low jitter performance below 1 ps RMS for high-speed serial interfaces like PCIe Gen 3/4.

Part Context

The SI5338N-B05026-GM belongs to the Si5338 family of I2C-programmable clock generators. This series is designed to replace multiple crystal oscillators by providing flexible frequency synthesis in a compact 4x4 mm QFN-24 package. The 'N' suffix typically denotes a specific factory-programmed configuration or pinout variant within the broader Si5338 product line.
