ECS-3951M
ECS-3951M/3953M Series
SMD Clock Oscillator
The ECS-3951M (5V) and ECS 3953M (3.3V) Series are
miniature, crystal controlled, low current clock oscillators in a
ceramic SMD package. Package is seam welded with a metal lid.
The low profile package is ideal for today’s advanced portable
PC and instrumentation designs.

*ECS-3953M is also compatible with a supply voltage of +3.0V DC ±0.3V
**Inclusive of 25°C tolerance, operating temperature range, input voltage change, load change, aging shock and vibration.
***An internal pullup resistor from pin 1 to 4 allows active output if pin 1 is left open.
Note: A 0.01 μF bypass capacitor should be placed between VCC (Pin 4) and GND (Pin2) to minimize power line noise.
