CPCI-6200 Installation and Use (6806800J66E) 93
4.10.3 USB (PCI Bus 4)
The USB 2.0 host controller (NEC uPD720101) provides USB ports with integrated transceivers
for connectivity with any USB-compliant device or hub. USB channel 1 is routed to a single USB
connector located on the front panel. DC power to the front panel USB port is supplied via a
USB power switch. This power switch provides soft-start, current limiting, over current
detection, and power enable for port 1.
4.10.4 PCI Bus Frequency
PCI 1 and 2 buses can operate from 33 MHz to 133 MHz depending on the PMC. The following
table shows the frequency selection and supported configurations. The switch setting is
controlled by the user while the rest of the signals are set automatically by the hardware.
4.11 Operation Modes
CPCI-6200 can be operated in three modes, with the PCI to PCI bridge (PCI6466) behaving
differently in each mode.
