mainly about differential voltage's minimum and maximum value.

Thx :lol:

The PECL voltage levels are:
V(OH) = Vcc - .9 V = 4.1 V nom.
V(OL) = Vcc - 1.7 V = 3.3 V nom.

Thkq
your picture is interesting 8)

i had ever found this by google.
But my supply voltage is 3.3V.
so i just hope to find other way.
 

You can still use vomit's equation:
V(OH) = 3.3 - .9 V = 2.4 V nom.
V(OL) = 3.3 - 1.7 V = 1.6 V nom.


Attached is a datasheet from ON Semiconductor's website (www.onsemi.com). They are probably the leaders in ECL/PECL type logic products.
