Working principle

The PL123E-09SC-R clock generator consists of a voltage-controlled oscillator (VCO), a low noise charge pump, a reference voltage source and a series of LC components. The VCO is designed to produce a sinusoidal output signal with a fixed frequency. The charge pump and reference voltage source provide adjustable and stable control voltages that can be used to tune the output frequency. The series of LC components act as filters to reduce noise and generate a clean output signal. The device is programmable with a single-pin boot-up procedure and can be operated from a wide range of voltages.

In summary, the PL123E-09SC-R clock generator is a high precision device designed to generate clock signals with a fixed frequency range. It is ideal for use in wearables, personal electronics, industrial automation, automotive applications and more. The clock generator features adjustable spread spectrum clock signals, low jitter, low power consumption, and a wide operational voltage range. It is a highly-integrated component that requires just one external resistor to set the output frequency and can be programmed through a one-pin boot-up procedure.
