SI5338N-B05315-GMR

Overview

The SI5338N-B05315-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. It operates on 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.

Feature Summary

• I2C-programmable synthesis of any frequency up to 710 MHz on four independent drivers
• Supports multiple output formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL
• 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 applications
• Ethernet switch and router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix B05315 against the manufacturer's official documentation to confirm pre-programmed frequency and format configurations. Ensure compatibility with the target system's I2C bus voltage levels and power supply requirements before procurement.

Selection Notes

Select this component when zero ppm frequency accuracy and glitchless frequency adjustments are required. Verify that the required output signal formats and frequencies fall within the supported ranges for each driver. Confirm that the input reference source matches the device's compatible input types, such as differential, CMOS, or crystal inputs.
