A25 Wideband Analog IF Assembly Description
A25 Wideband Analog IF Assembly Connections
The connections to and from the A25 Wideband Analog IF assembly are as
listed in Table 14-1 and as illustrated in Figure 14-1.
While the A25 Wideband Analog IF assembly has a connector (J502) that
connects to the PCI bus on the A8 Motherboard, none of the signals on this
connector are used. The connector is used to give greater stability to the
assembly.
