ECS ECS-500X-144-B

ECS-500X SERIES
TEMPERATURE COMPENSATED OSCILLATOR
The ECS-500X 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.
FEATURES
• Highly stable output over temperature
• Wide frequency range
• RoHS Compliant (Pb Free)
• TTL/CMOS Compatible
