Typical Applications
The PE42742 provides the high isolation required
by FCC part 15.115 regulation between the
television antenna and the cable plant. The
advantage of the PE42742 is that device
isolation / thru performance is maintained when
power is removed. This unique feature makes the
PE42742 ideal for set-top box and VCR
applications. The PE42742 supports signal flow
from RFC to RF1 and RF2 termination in the
unpowered state; similar to the powered state with
C1=C2 (both high or low).
