Preliminary Data Sheet
Generation of 2V Supply for the VSC8101/VSC8102
In a ECL system, -2V will be one of the standard supplies and the VSC8101/VSC8102 can be powered with
GND and -2V. However, for typical TTL systems, 2V is generally not available. In these applications, the 2V
supply can be generated easily from a 5V or 3.3V supply. There are several manufacturers who supply com-
plete single-chip linear regulators. Examples are:
