Phase noise and ADEV of the WR Switch using different TCVCXOs
This page is a summary of the results of Allan Deviation and Phase noise measurements done using a modified Grand Master (described in White Rabbit Switch performance in Grandmaster mode, second half of the document). The reference clock is provided through a WRS-SMA-clock-board.
The following table shows the phase noise perfomance of some VCTCXO taken into account. Click on the name of the VCTCXO to see the perfomance of WRS using the selected VCTCXO.
| VCTCXO| * Phase noise @ 1Hz | Phase noise @ 10Hz | Power
supply compatible | Footprint compatible | Availabe on stores
*|
| VM53S3 (currently installed) | -31 dBc/Hz (ref. 10MHz) | -86 dBc/Hz
(ref. 10MHz) | YES 3.0V | YES (5x3.2mm) | YES
