LCDA15-1
The LCDA15-1 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 unidirectional line in common mode (Line-to-
Ground). For common mode protection, The signal is
input at pins 2 and 3. Pins 1 & 4 are connected to
ground. The ground connection should be made
directly to the ground plane for best results.
ADSL Protection
Figure 2 shows a typical ADSL schematic diagram with
the LCDA15-1 configured to provide lightning and ESD
protection for the sensitive ADSL line driver. The
LCDA15-1 is connected from each line to ground on
the IC side of the line. The LCDA15-1 should to be
grounded to the system ground to provide a proper
reference.
