ECS-500X Datasheet, PDF (1/1 Pages) ECS, Inc. – TEMPERATURE COMPENSATED OSCILLATOR

ECS-500X SERIES TEMPERATURE COMPENSATED OSCILLATOR
The ECS-500X temperature compensated oscillator _FEATURES
covers a wide frequency range and offers a
• Highly stable output over temperature
highly stable output over temperature. An
• Wide frequency range
internal trimmer is a standard feature to tune the _{• RoHS Compliant (Pb Free)}
TCXO to its nominal frequency.
• TTL/CMOS Compatible
