SI5338N-B05753-GM

Overview

The SI5338N-B05753-GM is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero 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 frequencies 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.

Feature Summary

• MultiSynth technology enables any-frequency synthesis with 0 ppm accuracy across four outputs
• Flexible output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats
• Low phase jitter performance of 0.7 ps RMS typical
• Independent output voltage selection (1.5, 1.8, 2.5, or 3.3 V) per driver

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 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 package type matches the design footprint requirements.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single source. Verify that the desired output signal format and voltage levels match the available driver configurations. Check input reference frequency compatibility, ensuring it falls within the supported ranges for crystal, CMOS, or differential inputs.
