<DIV><FONT color=#000000 size=2 face=Arial>That will not be a problem with
Hermes since we have a much larger FPGA than on Mercury. In fact it should be
possible with the current Mercury board. Just need to try and find the
time to experiment.</FONT></DIV>

<DIV><FONT size=2 face=Arial>The receiver board (Mercury) incorporates a
Digital Down Converter that takes the 1.966Gbps ADC data at 16 bits per
sample and reduces it to 48/96/192ksps at 24 bits per sample. This
slower data is passed over the Atlas bus to either an Ozy board (USB
interface to the PC) or shortly an OzyII board (Gigabit
