ADC FMC board clock synchronization mechanism
The fmc-adc-100m14b4cha board is equipped with an on-board crystal oscillator from Silicon Labs. The Si570 (datasheet) can be programmed via the I2C interface to provide frequencies in the range 10MHz - 1.4GHz. When using multiple ADC mezzanine cards in a large experimental facility, it may be necessary to make sure the measurements they provide are synchronized. This synchronization can be provided via White Rabbit.
This page contans the specifications and implementation details of the mechanism used to synchronize multiple ADC mezzanine cards with a sub-nanosecond accuracy.
