Temperature Compensated Crystal Oscillators (TCXOs)
TCXOs with Voltage Control Function (VCTCXOs)
MERCURY
Since 1973
QMQF574T and QVMQF574T are QuikXO™ (quick-turn delivery) versions of the
MQF574 (a TCXO) and VMQF574 (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 7.0x5.0x2.5 mm SMD, the supply voltage can be either 2.5 V or
3.3 V, CMOS output logics and frequency up to 250 MHz. The 0.8 ~ 1.6 ps
typical phase jitter and lower current consumption (25 mA typical for 250 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 MQF574T and
the VMQF574T series
■ For lower phase noise and phase jitter (0.6 p. sec. typical), please refer to MQN574T and VMQN574T series.
■ For smaller footprint, 3.2 x 2.5 x 1.6 mm 6-pad SMD, with the same electrical performance, please refer to the
MQF326T, and the VMQF326T series.
