Crystal oscillator 10-30Mhz with digital frequency adjustment ± 100ppm
The V-Trans VT18DCXO crystal oscillator cell provides a low phase-noise output, with a low frequency variation over temperature.
Oscillation frequency can be digitally adjusted ( +/- 100ppm)
In power-down mode, the oscillator is bypassed. An external clock signal can be applied to “xin” pin.
Internal current reference generator allows the cell to be used as a stand-alone.
If a more accurate current reference is desired, for better control or extended range of oscillation frequency over PVT corners, the user can apply an external current reference. (25uA typical).
A such reference current can be provided by V-Trans Irefgen (resistor-less design +/-5%) or Refgen (with external reference resistor +/- 1%) libraries or any other third party IP.
