7.2.1 Overview
The major subsystems of MUSYCC are the host interface, the expansion bus
interface, and the serial interface. The host interface is PCI compliant. For other
references to PCI, see the PCI Local Bus Specification, Revision 2.1, June 1,
1995. The expansion bus and serial bus interfaces are similar to the host interface
timing characteristics; the differences and specific characteristics common to
either interface are further defined.
7.2.2 Host Interface (PCI) Timing and Switching Characteristic
Reference the PCI Local Bus Specification, Revision 2.1, June 1, 1995 for
information on:
• Indeterminate inputs and metastability
• Power requirements, sequencing, decoupling
• PCI DC specifications
• PCI AC specifications
• PCI V/I curves
• Maximum AC ratings and device protection
