Working Principle:

637V4476A2T Oscillators are based on phase locked loop (PLL) technique or voltage-controlled oscillator (VCO) technique. This PLL operates within the masterclock frequency range and is provided with reference clock input (18.43MHz to 55.56MHz) as well as control voltage input (0V to 5V). It uses high frequency isochronous clock (HIC) architecture having the capability of 150MHz Fout clock frequency. Moreover, it has a wide dielectric isolation of +-3KHz dynamic frequency offset.

The 637V4476A2T oscillators consist of a VCO, a divider chain, and a number of edge detectors and reference dividers. The VCO produces an output waveform with a frequency that is proportional to the input voltage. The dividers then reduce the frequency, which is then sent to the phase comparator to compare it to the reference clock. The edges of the waveforms are then detected, and the correct frequency is generated.

The 637V4476A2T oscillator has a wide operating temperature range (-40°C to +85°C) and high stability with low jitter, making it ideal for a variety of industrial, telecom and automotive applications. In addition, it also provides a quick start-up time of 25µs and high environmental immunity, making it suitable for any environment.

The 637V4476A2T oscillators offer great flexibility in design and operation. They can be easily adjusted to meet any particular requirement, from low-noise performance to extremely high speed. Their wide range of features and advantages make them perfect for a wide range of generation, synchronization, and control applications.
