SI5338H-B04836-GM

Overview

The SI5338H-B04836-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with configurable signal formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply and accepts flexible input references up to 710 MHz. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum output frequency of 710 MHz for differential signals, and an operating temperature range of –40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm precision.
• Highly-configurable output drivers support up to four differential outputs, eight single-ended outputs, or a combination thereof.
• Low phase jitter of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS standards.
• Independent frequency increment/decrement feature allows glitchless adjustments in 1 ppm steps.

Applications

• PCIe Gen1/2/3/4 systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific factory-programmed configuration associated with the B04836 suffix against the target design requirements. Confirm that the I2C/SMBus interface compatibility matches the system controller. Ensure the selected output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) align with the load specifications.

Selection Notes

Select this component when low-jitter synthesis for multiple disparate frequencies is required within a compact footprint. The Si5338 replaces multiple crystal oscillators and buffers. Verify that the input reference source (crystal, CMOS, or differential) falls within the supported frequency ranges defined in the datasheet.
