SI5338K-B01671-GM

Overview

The SI5338K-B01671-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers with 0 ppm precision. It supports input frequencies up to 710 MHz and generates outputs ranging from 0.16 MHz to 710 MHz across formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, drawing a typical current of 45 mA. It features low phase jitter of 0.7 ps RMS, independent output voltage control, and I2C/SMBus programming via ClockBuilder Pro software.

Feature Summary

• I2C-programmable synthesis with 0 ppm frequency accuracy using patented MultiSynth technology
• Four independently configurable output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input reference options including external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch and router timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON applications

Procurement Notes

Verify the specific ordering suffix B01671 against official Skyworks documentation to confirm factory configuration parameters. Ensure compatibility with I2C bus voltages between 1.71 V and 3.63 V by checking register settings if the bus voltage is below 2.5 V. Confirm package integrity for the 24-lead QFN form factor before integration.

Selection Notes

Select this component when zero ppm frequency accuracy and independent output format configuration are required. Ensure the design accommodates the 4 x 4 mm QFN-24 package and provides appropriate thermal management given the junction-to-ambient resistance. Validate that the target application requires support for high-frequency differential inputs up to 710 MHz.
