Oven controlled SC-cut crystals are used to give good temperature stability combined with the lowest possible phase noise. The Pascall OCXO series has already established itself as the industry leader in phase noise performance. The `NEW OCXOF' Series offers the same very low close-in phase noise combined with even lower noise floor and higher output power. Typical applications: Low noise Frequency Multipliers Phase noise test systems High performance synthesisers Radar & EW 03/09 Project9:Layout 1 18/3/09 16:06 Page 1 OCXO SERIES - ULTRA LOW NOISE CRYSTAL OSCILLATORS ELECTRONICS LIMITED Frequency range 40 - 140MHz -6 Tuning range +/- 6 x 10 Tune voltage 0 to +10V, positive slope Temperature stability Aging/ year Output power Harmonics Phase noise for 100MHz unit -30 to 70C: +/- 2 x 10 -7 -6 0.5 x 10 after 30 days 13dBm 2dB, 50 -20dBc Minimum guaranteed performance 10Hz level E -102 level 1 -100 level 2 -97 level 3 -95 level 4 -90 level 5 -85 100Hz 1kHz -137 -135 -132 -130 -125 -120 -164 -162 -160 -158 -155 -150 10kHz offsets -178 -176 -176 -176 -175 -174 dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz For performance levels at other frequencies, please consult the sales office.
