Application Fields

The SL15300ZC-14EH1T can be used in a wide variety of applications, from industrial, medical and military equipment to consumer electronics. It is also used in telecommunications systems, instrumentation, networking and computing equipment, as well as in embedded systems and audio/video products. Its main applications include timing, synchronization, frequency acquisition and rate-tracking.

Working Principle

The working principle of the SL15300ZC-14EH1T is based on the use of a phase-locked loop (PLL). A phase-locked loop is an analog circuit that uses input signals to synthesize an output signal with a fixed phase relation to the input signals. This device consists of an input signal source, a phase detector, a VCO (voltage controlled oscillator) and a lowpass filter. The input signal is used by the phase detector to create error signals, which are fed to the VCO. The frequency of the VCO output is proportional to the error signals. The output of the VCO is then filtered by a low-pass filter, which is used to reduce any unwanted noise, jitter or other artifacts from the output. The filtered signal is then divided down to create the output clock.

The SL15300ZC-14EH1T also has a number of features that help it achieve low jitter and high accuracy. It features a width-control loop that can be used to adjust the loop bandwidth, thus optimizing the loop performance for the specific application, and it has an integrated reference oscillator and an adjustable spread spectrum option. It also utilizes on-chip programmable equalization and prescaler, divider, and power-down/bypass modes.
