SI5338C-B05559-GMR

Overview

The SI5338C-B05559-GMR is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports core supply voltages of 1.8 V, 2.5 V, or 3.3 V and operates within an ambient temperature range of –40 °C to +85 °C. The device features flexible input references including external crystals (8–30 MHz), CMOS (up to 200 MHz), SSTL/HSTL (up to 350 MHz), and differential inputs (up to 710 MHz). Outputs support LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with frequencies up to 710 MHz for differential and 200 MHz for single-ended CMOS.

Feature Summary

• MultiSynth technology enables zero ppm precision synthesis on four independent outputs
• Supports PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliance
• Low phase jitter performance of 0.7 ps RMS typical
• Independent glitchless frequency adjustment 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 configuration encoded in the ordering suffix B05559 against the target system requirements using Skyworks ClockBuilder Pro software. Confirm that the QFN-24 package land pattern matches the recommended PCB layout specifications provided in the datasheet.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single low-jitter programmable source. Ensure the required output signal formats (LVPECL, LVDS, HCSL, etc.) and voltage levels are supported by the configurable output drivers. Verify that the input reference frequency falls within the specified ranges for the chosen input type.
