SI5338C-B04398-GM

Overview

The SI5338C-B04398-GM is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize 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 various formats such as LVPECL, LVDS, HCSL, and CMOS, with individual supply voltages of 1.5, 1.8, 2.5, or 3.3 V. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a core supply current of 45 mA, and operation within a temperature range of -40 to +85 °C.
