The 348RPLF is a high precision voltage controlled clock generator with two local oscillators, suitable for extended temperature range, voltage range and supply voltage fields. The device is based on a reverse current design, which employs two reference voltages and two local oscillators to produce a clock signal. The output clock frequency is programmed using an internal digital control register, which is adjustable from 0 Hz to mid-GHz frequency range. The output signal of the device is stable and accurate even when the input voltage and/or the power supply voltage are subject to modest transient changes. The 348RPLF is optimized for applications in communications, industrial and automotive fields.

The main feature of the 348RPLF is its wide operating temperature range, which is suitable for extreme environmental conditions. It offers a low input voltage range of 0.8 – 1.25 V and a supply voltage range of 0.8 – 3.3V. This voltage range makes the device suitable for a wide range of applications, including charge pump oscillators, LDO voltage regulators and other power management blocks. The 348RPLF is also able to time divider clock signals, which allows it to be used for various PLL and frequency synthesiser applications. The device can be programmed for pulse width correction and for time delay and jitter mitigation.

The working principle behind the 348RPLF is based on a unique reverse current design, which employs two reference voltages and two local oscillators to produce a stable clock signal. The first reference voltage is applied to a frequency divider to obtain a reference oscillator frequency, and the second reference voltage is applied to a second frequency divider to obtain an output clock frequency. The two references are used to control the frequency of the two local oscillators, which are subsequently compared and phase synchronized. The clock generator then combines the phase-synchronized local oscillators to generate a frequency-based output clock.

The 348RPLF is a versatile device, designed for a wide range of applications in communications, industrial and automotive fields. It is suitable for use in a wide range of applications, including charge pump oscillators, LDO voltage regulators, and other power management blocks. It is also suitable for use in PLL and frequency synthesiser applications, and can be programmed for pulse width correction and for time delay and jitter mitigation.
