TCXO’s & VCXO’s
FEATURES
Highly stable output over temperature
Wide frequency range
Industry standard DIP 14 pin lead spacing
TTL/CMOS Compatible
ECS-500 SERIES
TEMPERATURE COMPENSATED OSCILLATOR
The ECS-500 temperature compensated oscillator
covers a wide frequency range and offers a
highly stable output over temperature. An
internal trimmer is a standard feature to tune the
TCXO to its nominal frequency.
