A8500
HCMOS/TTL 5V
Surface Mount
Extended Temperature/COTS
1MHz to 150MHz
Features
Tiny 5x7 SMD form factor
Hermetically sealed for rugged environment
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 aging
RoHS Status
Applications
Any electronic circuit requiring 5V HCMOS clocking
that is exposed to very high or very low temperatures.
Owning to their 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 performance. A wide range of
frequencies is available from 1 MHz to 150 MHz with -40 to +85°C operation.
