Pletronics OSN4 Miniaturized Oven-Controlled Crystal Oscillators (OCXOs) combine a miniature footprint with high stability, supporting packet-based timing. Pletronics OSN4 OCXOs measure 9mm x 7mm, meaning the series can meet the diverse requirements found in high-speed data communication applications. OSN4 features a 3.3V nominal supply voltage and a 10MHz to 40MHz frequency range and comes in a 4-pad surface-mount (SMD) package.
