QMQF326 Series Temperature Compensated Crystal Oscillators (TCXOs)
QVMQF326 Series
TCXOs with Voltage Control Function (VCTCXOs)
MERCURY
Since 1973
QMQF326 and QVMQF326 are QuikXO™ (quick-turn delivery) versions of the
MQF326 (a TCXO) and VMQF326 (a VCTCXO) series, respectively. QuikXO™
products, either standard or custom frequencies are produced and shipped from
California USA in 3 to 5 days and available at Mercury eCommerce. They are
3.2 x 2.5 x 1.6 mm miniature SMD, the supply voltage can be either 2.5 V or
3.3 V and output logics include CMOS (up to 250 MHz), differential LVEPCL
or LVDS (up to 1.5 GHz). The 0.8 ~ 1.6 ps typical phase jitter and lower current
consumption (43 mA typical for LVPECL 622.080 MHz at 3.3 V) compared to
competitions make the series ideal for multimedia, Ethernet, and networking applications.
Relevant Categories:
■ For lower cost with regular lead time, please refer to the non- QuikXO™equivalent, the MQF326, and the
VMQF326 series.
■ For lower phase noise and phase jitter (0.6 p. sec. typical), please refer to the MQN326 and VMQN326 series.
■ For 7.0 x 5.0 x 2.5 mm with the same electrical performance, please refer to the QMQF574, QVMQF574 (CMOS; 4-pad),
and QMQF576, QVMQF576 (LVPECL or LVDS; 6-pad) series.
