Device Connection Options for Protection of Two
High-Speed Line Pairs
The LC05-6 is designed to protect four high-speed data
lines (two differential pairs) from transient over-volt-
ages which result from lightning and ESD. Protection
of two line pairs is achieved by connecting the device
as follows: Pins 1-4 are connected to line 1 of the first
pair (i.e. Tip 1) and pins 13-16 are connected to line 2
of the first pair (i.e. Ring 1). Pins 5-8 are connected to
line 1 of the second pair (i.e. Tip 2) and pins 9-12 are
connected to line 2 of the second pair (i.e. Ring 2). All
pins should be connected for best results. Minimize
parasitic inductance in the protection circuit path by
keeping the trace length between the protected line
and the LC05-6 as short as possible.
T1/E1 Linecard Protection
A typical T1/E1 linecard protection circuit is shown in
Figure 2. The LC05-6 is connected between Tip & Ring
on the transmit and receive line pairs. It provides
protection to metallic (line-to-line) lightning and ESD
surges. It is designed to meet the intra-building re-
quirements of Bellcore GR-1089. This design takes
advantage of the isolation of the transformer to
suppress common mode surges. To complete the
protection circuit, the SRDA05-4 (or SRDA3.3-4 for
3.3V supplies) is employed as the IC side protection
element. This device helps prevent the transceiver
from latching up by providing fine clamping of tran-
sients that are coupled through the transformer.
