Rossini Clock is it useful for me?

@AndrewS

Yes, IIUC both have an OCXO for 44.1kHz and a 48kHz VCXO which is slaved/referenced to it.

I would love to hear from you and/ or @James why dCS has chosen for this (new) combination of OCXO ánd VCXO. What is the benefit, compared to using 2 VCXOs?

@dCS_kb

dCS products use Voltage Controlled Crystal Oscillators (VCXOs) with a sync range of +/- 300 parts per million.

@James

The ability of a quartz crystal (or any piezoelectric material) to maintain a consistent oscillation frequency relies on having a stable, interference-free DC signal of the correct specification. In the case of both VCXOs and OCXOs, this means clean DC for the power supply. In the case of a VCXO, even more crucially, the control voltage needs to be stable (in this type of oscillator, the control voltage is used to make fine adjustments to the crystal’s frequency).
