SI4112-D-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI4112-D-GTR is a single-band RF synthesizer manufactured by Skyworks Solutions Inc. It integrates a Phase-Locked Loop (PLL) with an intermediate frequency (IF) output, designed for wireless communication applications. The device operates on a supply voltage ranging from 2.7V to 3.6V and supports a maximum output frequency of 1GHz. It utilizes a crystal input and provides one clock output circuit. The component is housed in a 28-WFQFN package with an exposed pad, measuring 5x5 mm, and is rated for operation between -40°C and +85°C.
