NH21M13LA

Crystal Oscillator
Model Name NH21M13LA
Oven-Controlled Crystal Oscillator (OCXO)
for Fixed Communication Equipment
■ Main Application
● Base stations for Mobile communication system
● Measuring instrument
● Synthesizer
● Exchanger
● High-end router
■ Features
● Compact, with a low height. (Compatible with 14-pin Dip)
● Excellent short-term stability (can be used instead of a TCXO because of its
higher precision).
● Excellent phase noise characteristics.(10MHz : -140dBc/Hz at 1kHz)
