EXAMPLE:
QT805URM-100.000000
would be a Flight Model version HF TCXO, 24 pin Double Dip, sine-wave 12 volts, stability ±1
ppm over -20…+70°C, @ 100 MHz with external tuning via external resistor.
QT805URE-100.000000
would be a Engineering Model version HF TCXO, 24 pin Double Dip, sine-wave 12 volts, stability
±1 ppm over -20…+70°C, @ 100 MHz with external tuning via external resistor.
