Extended Temperature/COTS  
XO, 5.0V  
20KHz to 100MHz  
RoHS Status  
Features  
Tiny 5 x 7 SMD form factor  
Hermetically sealed for rugged environmental  
conditions  
Extremely wide operating temperature range  
accommodates harsh environments  
All crystals are processed in-house with tight angle  
control to assure best frequency-temperature  
characteristics  
All units are vacuum baked before sealing at 175°C  
for 16 hours to eliminate moisture traces and pre-age  
units for superior stability  
Description  
Owing to their small size, light weight, and  
rugged characteristics, these 5V HCMOS  
extended temperature/COTS oscillators fulfill  
tasks not previously feasible. They are used in  
applications that take advantage of their  
extended temperature range and high  
Applications  
performance. Twenty four different models (with  
and without tristate) cover -55°C to +200°C  
operation and provide frequency selection from  
20 KHz to 100 MHz. They combine excellent  
long-term reliability, loading characteristics, and  
superior startup performance.  
Thru-hole PCB applications that require an  
HCMOS/TTL 5V clock and that might be  
exposed to extremely harsh environmental  
conditions.
