SI5338N-B05635-GMR

Overview

The SI5338N-B05635-GMR is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with 0 ppm precision 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 differential 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. Jitter performance is specified at 0.7 ps RMS typ.

Feature Summary

• I2C-programmable synthesis with 0 ppm frequency accuracy
• Four independently configurable output drivers supporting multiple signal formats
• Low phase jitter of 0.7 ps RMS typical
• Flexible input reference options including crystals, CMOS, and differential signals

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS applications
• Ethernet switch and 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 I2C pull-up voltages are compatible with the selected core supply voltage. Confirm moisture sensitivity handling requirements during storage and assembly.

Selection Notes

Select this component when zero-ppm frequency accuracy across multiple outputs is required. Verify that the target application frequencies fall within the supported ranges for the chosen output format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Ensure the system design accommodates the 4x4 mm QFN-24 package thermal characteristics.
