SI5338B-B06143-GMR

Overview

The SI5338B-B06143-GMR is an I2C-programmable quad clock generator manufactured by Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports a core supply of 1.8, 2.5, or 3.3 V and operates within a temperature range of –40 to +85 °C. Key electrical parameters include a typical phase jitter of 0.7 ps RMS and a maximum differential input frequency of 710 MHz. Outputs support LVPECL/LVDS up to 710 MHz, HCSL up to 250 MHz, CMOS up to 200 MHz, and SSTL/HSTL up to 350 MHz.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Low phase jitter of 0.7 ps RMS typical for high-performance timing applications.
• Highly-configurable output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats.
• Independent frequency increment/decrement feature allows glitchless adjustments in 1 ppm steps.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch/router clocking
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes
