DAPU OCXO is applied precision temperature control design and fuzzy compensation technique, so that the stability to reach the level of rubidium.
O23 Series (36 * 27 * 12.7mm) stability can reach 5E-11, in Holdover mode within 24 hours, the is less than 1uS;
O22 (25.4 * 25.4 * 12.7mm) series are smaller size, the stability is up to 5E-10, in Holdover mode within 24 hours, the stability is less than 5uS.
OCXO as a high-precision frequency source is applied to diverse of timing devices and base station, such as GSM, CDMA2000, TD-SCDMA, WCDMA and other standard base stations, time server, delicate test equipment, military communications equipment etc..
The full name of MCXO is digital temperature compensated crystal oscillator. It achieves a higher stability through a MCU compensating the frequency. DAPU MCXO owns a leading technology is this industry, the stability of MCXO is up to 1E-8
DAPU MCXO fully meets the ITU-T G.813 requirements for 3 stratum clock, the Holdover Stability in 24 hours could be better than 0.05ppm,; In 20 years, Free-run Accuracy is less than 3ppm.
MCXO has been large-scale replacement of Stratum 3 OCXO, compared with Stratum 3 OCXO, MCXO has smaller size, excellent resistance of vibration, shock and drop, power consumption is only 1 / 20 of 3 stratum OCXO, and it can be used instantly, and easily adapted to worse working environment.
MCXO is mainly used in SDH, PTN, wireless communications, as well as other equipments which demand a higher frequency stability and instant use.
Through proprietary ASIC compensation design, DAPU TCXO can reach a higher stability with a smaller volume. By 7 * 5 (mm), it can achieve the stability of 1E-7, and has excellent spectrum quality, the phase noise is up to -135dBc/Hz @ 1KHz.
DAPU TCXO has a variety of sizes, mainly including 20 * 12.7,12.7 * 12.7,14 * 9,7 * 5,5 * 3.2,3.2 * 2.5 (mm). It features higher stability, smaller size, low power consumption. They are mainly used in small radio base stations, navigation equipment, wireless terminals and other products.
Dapu VCXO is widely used in RRU, SDH, test and measurement, wireless coverage equipment etc. it features excellent phase noise and spurious performance. Waveforms are HCMOS, LVPECL, LVDS, the highest frequency is up to 700MHz. Main dimensions are: 14 * 9, 7 * 5,5 * 3.2, and customer orientation is welcome.
There are many options for waveforms, including HCMOS, LVPECL, LVDS, the size includes 7 * 5,5 * 3.2, the highest frequency is up to 700MHz.
