Epson Toyocom Expands Its Lineup of Smallest-Class VCXO for Mobile Handsets with

– TOKYO, Japan, September 27, 2006 –

Epson Toyocom Corporation has released the VG-4231CE *QEM Series VCXO. Measuring just 3.2 x 2.5 mm, the device is in the smallest class and is suitable for use with low voltages (1.8 V). While the device operates with a low consumption current and at low voltage with its size, it features wide frequency coverage. Epson Toyocom will start shipping samples from October 2006.

Demand is increasing for VCXO devices used for the clock function in image signal processors built into handheld devices such as digital terrestrial broadcast receiver units. In addition to a compact product with superior characteristics, power saving is a particular requirement for this application. In order to meet the demand, Epson Toyocom has added the 1.8 V-type VG-4231CE *QEM Series to its highly-regarded 3.2 x 2.5 mm size VG-4231CE Series, expanding the company’s lineup of devices in response to the need for power saving in handheld devices.

In this series, consumption current is 45% lower than in earlier models. Measuring just 3.2 x 2.5 mm, the device operates with a low consumption current and at low voltage while offering wide frequency coverage of APR ±80 x 10-6 Min. thanks to Epson Toyocom’s unique crystal oscillator fabrication technology and ultra high precision mounting technology.

These products will be on display at CEATEC JAPAN 2006 being held at Makuhari Messe from October 3 (Tuesday). Visit the Epson Toyocom booth (No. 5E03) to see the VG-4231CE *QEM Series and a wide range of other applied crystal devices up close.

Glossary

VG-4231CE *QEM: VG-4231CE CQEM or VG-4231CE PQEM

VCXO: Voltage Controlled X’tal Oscillator
A crystal oscillator circuit with a function for controlling the oscillating frequency by changing the voltage applied. The voltage controlled crystal oscillators that Epson Toyocom offers are the VG Series and TCO Series.

APR: Absolute Pull Range
APR = Frequency pull – (permissible frequency deviation + temporal change + shock + vibration and other frequency changes)
Permissible frequency deviation includes initial frequency deviation, frequency temperature behavior, source voltage fluctuation, load fluctuation, and reflow change. Aging of this series is assumed to be 5 years.
