General Description
The DSC1104 and DSC1124 series of high
performance oscillators utilizes a proven silicon MEMS
technology to provide excellent jitter and stability over
a wide range of supply voltages and temperatures. By
eliminating the need for quartz or SAW technology,
MEMS oscillators significantly enhance reliability and
accelerate product development, while meeting
stringent clock performance criteria for a variety of
communications, storage, and networking applications.
DSC1104 has a standby feature allowing it to
completely power down when EN pin is pulled low;
whereas for DSC1124, only the outputs are disabled
when EN is low. Both oscillators are available in
industry standard packages, including the small
2.5 mm x 2.0 mm, and are drop-in replacements for
standard 6-pin HCSL quartz crystal oscillators.
