3D Model

The SI4133 is a monolithic integrated circuit that performs IF and dual-band RF synthesis for wireless communications applications. This integrated circuit (IC), with minimal external components, completes the frequency synthesis function necessary for RF communications systems. The SI4133 has three complete phase-locked loops (PLLs) with integrated voltage-controlled oscillators (VCOs). The low phase noise of the VCOs makes the SI4133 suitable for demanding wireless communications applications. The SI4133 is programmed serially with 22-bit words comprised of 18-bit data fields and 4-bit address fields. The SI4133 may operate at an extended frequency range of 1850 MHz to 2050 MHz by connecting the RFLA and RFLB pins directly.

This article provides you with a basic overview of the SI4133 Integrated Circuit, including its pin descriptions, features and specifications, etc., to help you quickly understand what SI4133 is.
