IXP42X Product Line and IXC1100 Control Plane Processor
PCI Bus Signal Timings
NOTES:
USB Interface
For timing parameters, see the USB 1.1 specification. The IXP42X product line and IXC1100
control plane processors’ USB 1.1 interface is a device or function controller only. The IXP42X
product line and IXC1100 control plane processors’ USB v 1.1 interface cannot be line-powered.
1. See the timing measurement conditions.
2. Parts compliant to the 3.3 V signaling environment.
3. REQ# and GNT# are point-to-point signals and have different output valid delay and input setup times than
4. RST# is asserted and de-asserted asynchronously with respect to CLK.
5. All PCI outputs must be asynchronously driven to a tri-state value when RST# is active.
6. Setup time applies only when the device is not driving the pin. Devices cannot drive and receive signals at
7. Timing was tested with a 70-pF capacitor to ground.
8. For additional information, see the PCI Local Bus Specification , Rev. 2.2.
