SI5338A-B05923-GMR

Overview

The SI5338A-B05923-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 operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, consuming approximately 45 mA. Key features include low phase jitter (0.7 ps RMS typ), glitchless frequency adjustment in 1 ppm steps, and independent phase adjustment with <20 ps accuracy.
