Yes, Power Manager II device supports Hot Socketing. All the pins of the Power Manager II are Hot Socket complaint. There is no problem in applying maximum specified I/O voltages to the pins before VCCD or VCCA is applied. However small leakage ...
The larger two devices (LCMXO1200 & LCMXO2280) in the MachXO family support True LVDS I/O. To set up "true LVDS" on the input side, connect a 100 ohm terminating resistor across the 'true' and 'compliment' input terminals. On the output side, no ...
The phenomena is a spike which occurs when ramping a pad above and below VCCIO. There is a circuit which controls the NWELL voltage of the PMOS driver. The NWELL tracks VCCIO when the pad is below VCCIO and the NWELL tracks the PAD voltage when the ...
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 ...
