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

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.
FEATURES
• Highly stable output over temperature
• Wide frequency range
• Industry standard DIP 14 pin lead spacing
• TTL/CMOS Compatible
