This article will discuss the working principle and application field of the 655L16113C2T.

Overview

The 655L16113C2T is a voltage-controlled crystal oscillator (VCXO) designed for applications where very high frequency accuracy and stability are required. It has a typical frequency range of about 2.4-44MHz, with a wide range of supply voltages of 3V to 5.5V. It is an economical and reliable solution for frequency stabilization and is typically used in wireless communication systems, industrial control systems, and consumer electronics.

Working Principle

The 655L16113C2T utilizes a voltage-controlled crystal oscillator circuit to generate a stable frequency output. This circuit consists of a quartz crystal connected to a pair of varicap diodes, which are connected in parallel between a pair of buffers. The frequency of the oscillator is determined by the resonant frequency of the crystal, which is adjusted by changing the resistance of the varicaps. By increasing or decreasing the resistance of the varicaps, the frequency of the oscillator can be adjusted over a wide range.
