Features  
20kHz to 100MHz frequency range  
5X7 SMD form factor  
Hermetically sealed for rugged environmental  
conditions  
Extremely wide operating temperature range  
accommodates harsh environments  
Crystals are processed with tight angle control to  
assure best frequency-temperature characteristics  
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 3.3V 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  
Tristate feature optional  
Equivalent 5V parts are available in T1250 series  
performance. Twenty four different models (with  
and without tristate) cover -55°C to +200°C  
operation and provide frequency selection from  
20kHz to 100MHz. They combine excellent long-  
term reliability, loading characteristics, and  
superior startup performance.  
Applications  
Applications that require an HCMOS 3.3V clock  
and might be exposed to extremely harsh  
environmental conditions.
