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

and are “drop-in” replacement for standard

4-pin CMOS quartz oscillators.
