Epson Toyocom halves size of SAW oscillators
1 min read
Epson Toyocom Corporation, a specialist in crystal devices, has announced the development of a new series of differential output SAW oscillators that offer both stability and high frequency oscillation, from 100 MHz and up.
Measuring 5 x 3.2mm along the edges and 1.4mm thick, the SAW oscillators in the new EG-2121/2102CB series are, according to Epson, believed to be the smallest of their type in the world.
To meet market demand for smaller products, Epson Toyocom reduced the size of the SAW resonators and oscillation circuits that comprise these oscillators and further refined the precision packaging technology in order to squeeze more components into less space. The result is that the SAW oscillators in the EG-2121/2102CB series have a 50% smaller footprint than their predecessors yet still have high frequencies and stability.
The products, which support 2.5V and 3.3V LVDS and LV-PECL output, consume approximately 50% less current than their predecessors.
The products in the EG-2121/2102CB series oscillate at fundamental frequencies ranging from 100 to 700MHz. Phase jitter(*5) is 0.5 ps, while frequency tolerance is ±50 x 10-6.
These oscillators use a SAW resonator engineered to be resistant to oscillation defects induced by particles and other foreign substances, while a built in low noise regulator enables them to withstand fluctuations in the external power supply.
Samples are currently available for evaluation. Commercial development is scheduled for December 2011.
