SI5338A-B04524-GMR

Overview

The SI5338A-B04524-GMR is a programmable quad clock generator utilizing 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. Output formats include LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL, with frequencies ranging from 0.16 MHz to 710 MHz depending on the format. It features low phase jitter of 0.7 ps RMS typical, operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, and draws 45 mA typical current. The component is housed in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Low phase jitter of 0.7 ps RMS typical with high precision zero ppm frequency accuracy.
• Flexible input reference support: external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential (5–710 MHz).
• Independent frequency increment/decrement for glitchless adjustments in 1 ppm steps.

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems.
• Ethernet switch/router and 1 GbE/10 GbE interfaces.
• Processor and FPGA clocking.
• Broadcast video/audio timing.
• Telecom line cards and MSAN/DSLAM/PON equipment.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm configuration details. Ensure compatibility with I2C/SMBus programming requirements using ClockBuilder Pro software. Confirm that the selected output voltage levels match the target load requirements for LVPECL, LVDS, or CMOS formats.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single source. Verify that the desired output signal format (LVPECL, LVDS, HCSL, etc.) falls within the supported frequency ranges specified in the datasheet. Ensure the input reference source matches the electrical characteristics supported by the IN pins.
