Product Details
Model Name: 3225 MEMS OSC 24.000MHZ
Part Number (SJK): 3NM24000C33YC
Minimum Packaging: 3000pcs/real
Dimensions
Package Size: 3.2x2.5mm (Units: mm)
Test Circuit Description
Control Input (Output Enable/Disable):
- Logic 1 or open on Pad 1: Oscillator output enabled.
- Logic 0 on Pad 1: Output disabled to high impedance.
Waveform Conditions
Waveform measurement system should have a minimum bandwidth of 5 times the frequency being tested.
Output Enable/Disable Delay
The device timing during normal operation is illustrated. When the device is in standby, the oscillator stops. Upon release from standby, the oscillator starts, and a stable output occurs after a short delay.
