Detailed Description
R
45. System Monitor
The ML50
x
supports both the dedicated and the auxiliary analog inputs to the Virtex-5
FPGA System Monitor block. The VP and VN pins shown in
Table 1-34, page 50
are the
dedicated pins, whereas the VAUXP[
x
], VAUXN[
x
] represent the 16 user-selectable
auxiliary analog input channels. The ML50
x
PCB layout for the VP and VN pins is
designed using differential pairs and anti-alias filtering in close proximity to the FPGA as
recommended in the
Virtex-5 FPGA System Monitor User Guide
[Ref 14]
. Please note that the
circuitry connected to the 16 AUX channels on the ML50
x
are connected in a non-optimal
fashion as they are implemented without anti-alias filtering at the FPGA. This tradeoff was
