Oscillators

Oscillators provide the basis for frequency stability, providing a reference point to measure other frequencies against. Oscillator technology forms the foundation for high performance synchronisation, frequency division, frequency synthesis, signal modulation and many other processes.

The SIT8208AI-2F-25E-20.000000Y, which is part of the SMASH family from Sitronix, is a cost effective, low jitter, low power, 50 MHz clock oscillator. It features a 20-pin chip-on-board package, provides an enable/disable function, and is backwards-compatible with existing SIT8208AI packages.

Application Field

The stable frequency clock output from the SIT8208AI-2F-25E-20.000000Y is suitable for a wide range of applications including USB and Gigabit Ethernet applications; high performance PCI Express, DDR2, SATA and SDRAM interfaces. It is also used for high speed Serdes applications, including SONET, 2G/3G/4G/5G Mobile Phone backhaul, High Definition Video, Gigabit Base-T Ethernet, and other Industrial and Network Applications.

Working Principle

The oscillator works on the principle of generating a stable signal oscillation by feeding being energized by a steady power source. It consists of a resonator, amplifier, and feedback loop system. The resonator creates an electrical signal with a constantly repeating waveform, which is then sent to the amplifier. The amplifier then increases the signal strength and sends the signal back into the resonator, creating a continuous loop. The signal will keep repeating until the power source is lost.

The SIT8208AI-2F-25E-20.000000Y clock oscillator provides accuracy of ±50ppm with a frequency tolerance of ±20ppm over the -40°C to +85°C temperature range. The output frequency is temperature compensated over the full operating temperature range and is put through a series of stringent tests, including aging and environmental tests.

The SIT8208AI-2F-25E-20.000000Y clock oscillator provides extremely low noise and jitter performance as well as superior signal quality for providing reliable timing signals for a variety of applications.
