What is the maximum load that MultiLINX can drive? What are the voltage characteristics?

解决方案

The MultiLINX cable was designed as a configuration prototyping tool for 1 to 4 Xilinx programmable logic devices, which are connected using the MultLINX's flying wires. If you need the MultiLINX cable to drive a large number of loads, its best to use buffers to maintain the MultiLINX signal integrity. 

The worst-case load for each of the MultiLINX flying wires: 

max capacitive load: 100pF 

max pullup resistance: 500 ohms 

max pulldown resistance 5000 ohms

3.3V and 5V Vih,Vil,Voh,Vol 

Vih(min) = 1.65V 

Vih(max) = 5V 

Vil(min) = 0V 

Vil(max) = 1.5V 

Voh(min) = 2.4V 

Voh(max) = 5V 

Vol(min) = 0V 

Vol(max) = 0.4V

2.5V Vih,Vil,Voh,Vol 

Voh(max) = 2.5V 

Voh(min) = 2..0V 

Vol(max) = 0.4V 

Vol(min) = 0V 

Vih(max) = 5V 

Vih(min) = 1.65V 

Vil(max) = 1.5V 

Vil(min) = 0V
