Epson Toyocom Announces Smallest-Class VCXO for Mobile Handsets
with Support for Terrestrial Digital Broadcasts
Epson Toyocom Corporation has announced that it is preparing to release a
new series of voltage-controlled X’tal (crystal) oscillators (VCXO) that support
mobile handsets capable of receiving terrestrial digital TV broadcasts.
Measuring just 3.2 x 2.5 mm, the VG-4231CE Series will be among the
smallest-footprint crystal solutions in the industry yet will offer frequency
control characteristics equivalent to their predecessors. This will allow them to
meet the ongoing demand for miniaturization while also easily handling the
complicated timing of high-quality image recording signals. Samples will begin
shipping in February 2006.
Demand is rising for VCXOs that are small yet offer good characteristics,
especially in burgeoning applications such as tuners for receiving one-segment
digital multimedia broadcasting (DMB) services that deliver terrestrial digital
TV broadcasts to mobile handsets. Other applications include applications as
clocks for controlling the timing of video signals, which have become
increasingly complicated due to the advent of high-quality image recording as so
forth.
In response to these needs, the VG-4231CE Series, despite a package that is
among the smallest in the industry (3.2 x 2.5 x 1.2 mm), offers a frequency
control range of

or better. In addition, circuit design is facilitated by
providing 1 M
or more of voltage controlled input resistance. The new VCXOs
will be available in supply voltages of 2.8 V and 3.3 V.
