I/O Structure  
PCI Compliance  
The MAX V 5M1270Z and 5M2210Z devices are compliant with PCI applications as  
well as all 3.3-V electrical specifications in the PCI Local Bus Specification Revision 2.2.  
These devices are also large enough to support PCI intellectual property (IP) cores.  
Table 2–5 shows the MAX V device speed grades that meet the PCI timing  
specifications.

LVDS and RSDS Channels  
The MAX V device supports emulated LVDS and RSDS outputs on both row and  
column I/O banks. You can configure the rows and columns as emulated LVDS or  
RSDS output buffers that use two single-ended output buffers with three external  
resistor networks.

Schmitt Trigger  
The input buffer for each MAX V device I/O pin has an optional Schmitt trigger  
setting for the 3.3-V and 2.5-V standards. The Schmitt trigger allows input buffers to  
respond to slow input edge rates with a fast output edge rate. Most importantly,  
Schmitt triggers provide hysteresis on the input buffer, preventing slow-rising noisy  
input signals from ringing or oscillating on the input signal driven into the logic array.  
This provides system noise tolerance on MAX V inputs, but adds a small, nominal  
input delay.  
The JTAG input pins (TMS, TCK, and TDI) have Schmitt trigger buffers that are always  
enabled.

The TCKinput is susceptible to high pulse glitches when the input signal fall time is  
greater than 200 ns for all I/O standards.
