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.

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