Reducing drive strength can be used to save dynamic power. The savings will be in the uA range. Reducing drive strength will improve Simultaneous Switching Output (SSO).
Description: This article lists the default drive strength for different IO_TYPE for Nexus products. Solution: For Nexus products, these are the default drive strength set in Radiant SW according to the IO_TYPE, and they are applicable for both Wide ...
Situation: An application uses the LatticeXP2 device and needs the sub-LVDS output type. Solution: Given that sub-LVDS signaling requires Vod from 100mv (min) to 200mv (max) and Vcm from +0.75v (min) to +1.05v (max), the sub-LVDS output type can be ...
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 ...
If user's design is using 50 ohm PCB trace and cable impedances, user can set the LatticeXP2 IO output type to LVDS and this will produce 400mv peak signal swing at the receiver's 100 ohm termination with proper common mode output voltage. The ...
