SI5338A-B01603-GMR

Overview

The SI5338A-B01603-GMR is an I2C-programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm accuracy. The device supports differential and single-ended outputs including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. Input references range from external crystals (8–30 MHz) to differential clocks up to 710 MHz. Key electrical parameters include a typical core supply current of 45 mA, operating voltage of 1.8/2.5/3.3 V, and a typical phase jitter of 0.7 ps RMS. It operates within a temperature range of –40 to +85 °C in a 24-QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with true zero ppm precision.
• Low phase jitter performance of 0.7 ps RMS typ, compliant with PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS standards.
• Highly configurable output drivers supporting up to four differential or eight single-ended outputs with independent voltage levels (1.5, 1.8, 2.5, or 3.3 V).
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).

Applications

• PCIe Gen1/2/3/4 systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the programmed frequency plan and output configuration. The 'GMR' suffix indicates tape-and-reel packaging. Confirm that the required I2C programming data matches the intended application design before procurement.

Selection Notes

Select this component when independent frequency synthesis for multiple domains is required without using multiple crystal oscillators. Ensure the target output formats (LVPECL, LVDS, etc.) and frequencies fall within the specified ranges. Verify that the input reference source matches one of the supported types, such as differential clocks up to 710 MHz or external crystals between 8 and 30 MHz.
