topic.
The ACB also receives 12Vdc via the backplane and supplies 9Vdc to
the CB FPGAs.
Channel Board
The main function of the Channel Board (CB) is to transmit and
receive data from the transducers and perform Analog to Digital
Conversion (ADC) on the data received from the transducers along
with Digital to Analog Conversion (DAC) on signals going to the
transducers.
The 128-Channel Board (CB) transmits transducer data over 8 high
speed serial links to the ACB when it receives the Xmit Start signal
from the ACB.
The CB contains the digital beam-former FPGAs, Neon0 and Neon1,
the analog front end circuitry, 14-bit analog to digital converters on
each channel and high voltage regulation for the transmitters.
