Daughterboard for the White Rabbit Switch
General description of the board
The aim of the board is to improve the performance of the WR Switch
using an external PLL and a new VCTCXO.
A prototype of this board has been tested successfully, however the
prototype lacks in terms of flexibility, since it requires external
hardware to make it works.
The board has a new external 10 MHz input, to be used instead of the
current 10 MHz input of the switch.
The board is intended to be mounted inside the switch, using the
installed 12V power supply of the WRS.
The proposed board can be installed in any PCB v3.3 and v3.4 versions of
the switch. The following steps are required to install the board inside
the switch:
- Soldering of the SMI link connector: this can be easily done with an hot air-gun. Three switches have been modified with 100% sucess rate
- Remove of the VM53S3 oscillator and install of an U.FL connector
