10MHz SC-Cut High Stability OCXO 5050 DIP-5 (50.8x50.8mm)

Frequency: 10MHz
Supply Voltage: 12V
Output Waveform: Sinewave
Temperature characteristics: ±2ppb
Phase Noise: -118dBc/Hz@1Hz

This high-performance 10MHz OCXO in a standard 5050 DIP package delivers ultra-low close-in phase noise (-118 dBc/Hz @ 1Hz) and exceptional short-term stability (1s ADEV < 2E-13). Featuring a 12V power supply and low-distortion sine wave output, it serves as an ideal precision frequency reference for GPSDOs, advanced test equipment, and high-end audio master clocks.

Features

·Nominal Frequency: 10.000 MHz standard precision reference

·Ultra-Low Phase Noise: -118 dBc/Hz @ 1Hz, -145 dBc/Hz @ 10HZ, and -170 dBc/Hz noise floor @ 10kHz

·Outstanding Short-Term Stability: Allan Deviation (ADEV) <2 X 10-13 @ 1s, < 3 X 10-13 @ 10s

·Tight Temperature Stability: Frequency stability of 2 ppb across -40°C to + 70°C

· Low Aging Rate: Daily aging ≤ +0.1 ppb/day, yearly aging ≤ +0.02 ppm/year

· Clean Sine Wave Output: Output level 9+2 dBm into 50 02, harmonics S -40 dBc, spurious  -80 dBc

· Electronic Frequency Control (EFC): O to 5.OV voltage tuning with built-in +5.0V reference voltage output (Vref)

·Standard Industrial Packaging: Robust 5050 DIP metal hermetic package (50.8 x 50.8 x 19.0 mm) with superior RF shielding
