SI5338M-B04914-GMR

Overview

The SI5338M-B04914-GMR is a programmable quad clock generator utilizing Skyworks MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision. The device supports flexible input references, including differential inputs up to 710 MHz and single-ended CMOS inputs up to 200 MHz. Outputs are configurable for LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats. Key electrical parameters include a core supply voltage range of 1.71 V to 3.63 V, typical core current of 45 mA, and a maximum operating temperature of +85 °C.

Feature Summary

• Low phase jitter of 0.7 ps RMS typical
• Independent glitchless frequency adjustment in 1 ppm steps
• Highly configurable spread spectrum (SSC) from 0.5% to 5.0%
• I2C/SMBus compatible interface with ClockBuilder Pro support

Applications

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

Procurement Notes

Verify the specific ordering suffix B04914 against the manufacturer's official documentation to confirm factory-programmed register settings. Ensure the I2C pull-up voltage requirements align with the system design, as compatibility adjustments may be necessary for voltages below 2.5 V.

Selection Notes

Select this component when low jitter synthesis and flexible output format configuration are required. Verify that the target application frequencies fall within the supported ranges for the chosen output driver types, such as LVDS/LVPECL up to 710 MHz or CMOS up to 200 MHz.
