Revision 1.12 – July 17, 2008
Table 7. Signal Functional Description (Part 2 of 10)
Notes:
1. Receiver input has hysteresis
2. Must pull up (recommended value is 3kΩ to OV
3. Must pull down (recommended value is 1kΩ)
4. If not used, must pull up (recommended value is 3kΩ for LVTTL or 8.2kΩ for PCI to OV
5. If not used, must pull down (recommended value is 1kΩ)
6. Strapping input during reset; pull-up or pull-down required
