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.

随着阅读器与标签价格的降低和全球市场的扩大，射频标识 RFID(以下简称RFID)的应用与日俱增。标签既可由阅读器供电(无源标签)，也可以由标签的板上电源供电(半有源标签和有源标签)。由于亚微型无源 CMOS 标签的成本降低，库存和其他应用迅速增加。一些评估表明，随着无源标签的价格持续下降，几乎每一个售出产品的内部都将有一个 RFID 标签。由于无源 RFID 标签的重要性及其独特的工程实现...[详细]
