SI5338K-B05616-GMR

Overview

The SI5338K-B05616-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent outputs with zero ppm precision. The device supports differential and single-ended formats 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 core supply voltage of 1.8 V, 2.5 V, or 3.3 V, typical operating current of 45 mA, and package type QFN-24.

Feature Summary
