EXAMPLE:
QTV722AURM-50.000000 would be a Flight Model version VCXO, 32 pin SMD flat pack, HCMOS 3.3 volts, 40/60
symmetry, overall frequency stability (including Operating Temperature, ±5% Load Change, ±5% Supply Voltage
change. 10 year aging, and radiation)±45 ppm over -40…+85°C, @ 50 MHz with frequency pulling range from minimum
of 90 ppm below center frequency at 0V to a minimum of 90 ppm above center frequency at 3.3V.
