Its Achille’s heel in terms of accuracy is the plain crystal oscillator it uses as a frequency standard, which has no temperature compensation and thus drifts by about 0.2 ppm per degree.

Q-Tech Corporation has announced the introduction of the AXTAL GHz Series of crystal oscillators and modules to the U.S.

Synthesized converters use a synthesizer circuit (normally a PLL) to produce the desired frequency, while crystal controlled devices converter use a crystal oscillator to produce the desired frequency ...
