ECS-50-S-5PX-TR

Crystals are a fundamental component in many electronic systems. The ECS-50-S-5PX-TR is a triple-conversion frequency synthesizer crystal oscillator that is ideal for use in wideband communications, signal acquisition and critical timing applications due to its low-phase noise and excellent stability. This crystal oscillator is fully compliant with the latest Military Standard (MIL-STD-883) and performing temperature range from -55°C to +85°C.

The ECS-50-S-5PX-TR oscillator features a hybrid construction design of a quartz-based resonator and a frequency-locked phase-locked loop (PLL). The quartz-based resonator is a three-legged tuning fork, which consists of two identical quartz plates bonded together. Specifically for the ECS-50-S-5PX-TR oscillator, the quartz resonator has a frequency tolerance of100 parts per million (ppm).

The frequency-locked phase-locked loop (PLL) applies a negative-feedback loop to the oscillator circuit to maintain the output frequency close to its natural or resonance frequency. This is done by detecting any change in the input frequency, and then adjusting the output frequency to counter the change. The PLL also provides a low-noise output signal, with a noise floor as low as -100 dB/Hz.

The ECS-50-S-5PX-TR design is based on a core oscillator, which consists of an amplifier, a frequency divider and a phase detector. The amplifier is used to amplify the output signal from the quartz-based resonator to the desired level. The frequency divider divides the amplified signal by fixed and varying integer values. And the phase detector senses the difference between the output fraction of the frequency divider and the output of the quartz-based resonator and further adjusts the output of the amplifier to minimize the difference and maximize the stability of the quartz-based oscillator.

The ECS-50-S-5PX-TR crystal oscillator is designed for wide range of applications in military, aerospace, and telecommunications systems. It is ideally suited for timing applications such as clock and timing synthesis, hot standby systems, embedded waveform generation and transmission frequency synthesis. The excellent noise floors, low current consumption and small footprint makes it suitable for applications that require superior performance and economy.

In summary, the ECS-50-S-5PX-TR is a highly reliable and stable crystal oscillator designed for use in high-precision, low-noise applications. It features a hybrid construction design comprised of a quartz-based resonator and a frequency-locked phase-locked loop (PLL). The PLL provides a low-noise output signal, with a noise floor as low as -100 dB/Hz, while the quartz-based resonator has a frequency tolerance of 100 parts per million (ppm). This combination makes this crystal oscillator suitable for a wide range of applications in military, aerospace, and telecommunications systems.
