General Description
The DSC63xxB family of devices is the industry’s
smallest and lowest-power spread-spectrum MEMS
oscillators. Available in three different package sizes
with operating current as low as 3 mA, the smallest
4-pin package is a mere 1.6 mm x 1.2 mm in size. The
devices support up to ±2.5% or –3% spread spectrum
that can achieve up to 15 dB electromagnetic
interference (EMI) reduction. Because of industry
standard package and pin options, customers can
solve last minute EMI problems simply by placing the
new DSC63xxB on their current board layout with no
redesign required.
The DSC63xxB family is available in 1.6 mm x 1.2 mm
and 2.0 mm x 1.6 mm, and 2.5 mm x 2.0 mm
packages. These packages are “drop-in” replacements
for standard 4-pin CMOS quartz crystal oscillators.
