DSC8101 Series
2.5 to 3.3V PureSilcon™ Programmable CMOS Oscillator with Standby
Advanced Datasheet
General Description
The DSC8101 is a field programmable silicon
MEMS based CMOS oscillator offering excellent
jitter and stability performance over a wide
range of supply voltages and temperatures.
Using the TIMEFLASH programmer, the end
user can program the DSC8101 from 10 to
170MHz in increments of 100Hz (up to four
decimal point resolution). The nominal
operational supply voltages span from 2.5V to
3.3V and the device is offered in temperature
grades from Commercial (0ºC to 70ºC) to
Automotive (-55ºC to 125ºC).
Available in industry standard 7X5mm, 5X3.2
and 3.2X2.5mm packages, the DSC8101 is a
“drop-in” replacement for a standard 4 pin
quartz oscillator. The DSC8101 is electrically
identical to the DSC1101.
