The TWSAFB-LT FIFO buffer provides the custom protocol to feed the TWSAFB-OIDAM/DAM1021 DAC with sign magnitude notation. This architecture allows to implement a true FIFO buffer wich isolates the source from the DAC. TWSAFB-OI board allows full optical isolation.
This architecture allows the use of low phase noise external oscillators in place of the DAM1021 local clock. The TWSAFB-LT FIFO buffer allows to implement the DAC calibration in order to reach true 24 bit accuracy.
