Applications Information
Device Connection for Metallic Protection of High-
Speed Data Lines
The LCDAxxC-1 is designed to protect high-speed data
lines from transient over-voltages which result from
lightning and ESD. The device is designed to protect
one line in common mode (Line-to-Ground) or one line
pair in metallic (Line-to-Line) mode. For metallic mode
protection, the input of line 1 is connected at pin 1 and
the output is connected at pin 4. Likewise, the input
of line 2 is connected at pin 2 and the output is con-
nected at pin 3. For common mode protection, ground
either pins 1 & 4 or pins 2 & 3. The ground connection
should be made directly to the ground plane for best
results.
ADSL Protection
A typical ADSL protection circuit is shown in Figure
3. The LCDA12C-1 (or LCDA15C-1 for 15 volt drivers)
is connected from each line to ground on the IC side of
the line. They provide lightning and ESD protection for
the sensitive line driver IC.
