Epson Toyocom’s U.S.-Based Timing Products Division Announces Development of GHz-Band, High-Stability SAW Oscillators with Low Phase Noise and Low Jitter

El Segundo, CA (Vocus) October 14, 2008

Epson Toyocom Corporation’s U.S.-based Timing Products Division has announced the development of two new models of low phase-noise, low-jitter SAW oscillators that output GHz band (800 MHz – 2.5 GHz) frequencies at the fundamental. Commercial development is scheduled for completion in the first half of 2009.

The newly developed oscillators are the single-output EG-9000GC and the voltage-controlled EV-9000GB. The low phase noise, low jitter and excellent frequency-temperature coefficient characteristics of the oscillators are achieved by the built-in NS-34R crystal-oscillating element. The NS-34R boasts a high Q value, low insertion loss, high power durability, and an outstanding frequency-temperature coefficient, in addition to Epson Toyocom’s unique high-frequency circuit technology.

Phase noise is mitigated in the low offset frequency range (roughly 500 kHz up to 1.5 MHz) by taking advantage of the high Q value of the NS-34R. Phase noise is mitigated in the high offset frequency range (from roughly 500 kHz to 1.5 MHz or more) by taking advantage of the NS-34R’s high-power durability characteristics to raise the level of signals in the oscillation loop. The oscillators boast an extremely stable frequency-temperature coefficient that is 1/5 that of a conventional dielectric resonator oscillator and 1/3 that of an oscillator employing an STW (surface transverse wave) crystal.

The EG-9000GC and EV-9000GB will help provide performance gains in applications that require high frequencies and a highly stable clock (one with low phase noise, low jitter, and an excellent frequency-temperature coefficient). Communications and measurement applications will be particular beneficiaries. These oscillators are expected to contribute to the discovery of new technologies and the development of new products in applied microwave technology markets.

Main Features

Support fundamental frequencies from 800 MHz to 2.5 GHz
Low phase noise and low jitter due to newly developed SAW resonator that provides both a high Q value and high power durability
Highly stable oscillations due to new resonator’s superior frequency-temperature coefficient
Low power design (3V and 35mA)
