MK-Q-B-P-D-110410-01-2
Programmable Low-Jitter Precision CMOS Oscillator
DSC8101
DSC8121
General Description
The DSC8101 & DSC8121 series of high
performance field-programmable oscillators
utilizes a proven silicon MEMS technology to
provide excellent jitter and stability over a
wide range of supply voltages and
temperatures. Using the TIMEFLASH
programmer, the end user can easily
program the oscillators’ frequency in the field
for immediate testing or use in advance
prototype development or production.
DSC8101 has a standby feature allowing it to
completely power-down when EN pin is
pulled low; whereas for DSC8121, only the
outputs are disabled when EN is low. Both
oscillators are available in industry standard
packages, including the small 3.2x2.5 mm2,
and are “drop-in” replacement for standard
4-pin CMOS quartz oscillators.
