The DS1087LU-13C+T is a multifunctional oscillator that is suitable for a variety of applications. It combines a low-power low-jitter frequency synthesizer and a temperature-compensated crystal oscillator (TCXO) into a single device. This results in a product that can work as a pulse generator, a clock generator, a frequency synthesizer, or a temperature-compensated oscillator (TCO).

In a pulse generator application, the DS1087LU-13C+T can produce pulse widths to 8 ns, with jitter of less than 0.5 ps. The PLL features an adjustable frequency range of 10 kHz to 35 MHz and is suitable for clock multiply and divide operations. The TCXO provides frequency stability of +/-5 ppm from -40°C to +85°C, with a jitter of only 2.5 ps. This makes it suitable for use in a wide range of temperature-sensitive applications.

In terms of working principle, the DS1087LU-13C+T is composed of two main elements. The first is the PLL circuit, which is responsible for frequency multiplication and division. The second is the TCXO, which is responsible for frequency stability over temperature. The PLL and TCXO are connected via a phase-locked loop (PLL), so that the output frequency of the device is automatically adjusted based on the input frequency and temperature.

When the input frequency deviates from the nominal value, the PLL uses the feedback signal from the TCXO to adjust the output of the device. The TCXO, meanwhile, accounts for temperature-related frequency changes, automatically adjusting the output frequency as necessary. This combination results in a device that can maintain high frequency accuracy over a wide temperature range.

In addition to its use as a generator and synthesizer, the DS1087LU-13C+T can also be used as a temperature-compensated oscillator (TCO). The TCO is designed to compensate for frequency changes due to temperature changes, providing temperature-dependent frequency stability of +/-5 ppm from -40°C to +85°C.

The DS1087LU-13C+T is a versatile and reliable device with a wide range of uses. It is suitable for use as a pulse generator, a clock generator, a frequency synthesizer, or a temperature-compensated oscillator. The PLL and TCXO work together to provide high frequency accuracy over a wide temperature range, making the device suitable for temperature-sensitive applications. As such, it is an ideal choice for a variety of applications in the clock/timer field.
