SI5335B-B06139-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5335B-B06139-GMR is a web-customizable, any-frequency, any-output quad clock generator and buffer manufactured by Skyworks Solutions. It synthesizes four non-integer-related frequencies up to 350 MHz using MultiSynth technology, ensuring 0 ppm frequency synthesis error. The device supports flexible input references including external crystals (25/27 MHz), CMOS, SSTL/HSTL, and differential inputs. Outputs are independently configurable for LVPECL, LVDS, CML, HCSL, CMOS, or SSTL/HSTL formats with selectable supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It operates on a single core supply of 1.8, 2.5, or 3.3 V, consumes 45 mA in PLL mode, and functions within an ambient temperature range of –40 to +85 °C.
