6167 - [CrossLink] I/O: What is the max speed in MHz for subLVDS input when the banks are powered with 1.8V?
The maximum speed for subLVDS is 600MHz and this is the same when VCCIO is equal to 1.8V, 2.5V, and 3.3V.

The user can power up the Lattice MachXO2 part using only the VCC core and one VCCIO bank. There are, however, a few constraints: As per the "Typical I/O Behavior During Power-up" section of the MachXO2 Family Data Sheet, the user needs to pick ...
7312 - Crosslink: How to implement OPENDRAIN on Bi-Directional I/O port in CrossLink device?
CrossLink I/O does not have OPENDRAIN support for bi-directional pins. This feature is limited by the device hardware itself. However, this product still offers OPENDRAIN support but only limited to output ports only.

Bank 3, 4, and 5 are the High Speed Banks that support True LVDS. For Bank 6 and 7, although pins can operate through differential pair, its speed is limited to LVCMOS (Input and Output) or LVDS25E (output). Single ended termination with programmable ...

What is the meaning of "I/O Tristate Voltage Applied" and "Dedicated Input Voltage Applied" specified in the Absolute Maximum Ratings section of MachXO data sheet?
Solution: There are two cases where an IO pad is driven by an external source. One is the case of a dedicated input pad, and the other is a bi-directional IO pad in which its output can be tri-stated. The "Dedicated Input Voltage Applied" and "I/O ...
