u Ground isolation for 75 Ohm video/data lines

u 10 Hz to 7 MHz bandwidth

u Low insertion loss

u Insulated BNC connectors

u Excellent discrimination against power line inter-

ground potentials

The TC8235GIT is a one-to-one isolation transformer

for 75 Ohm coax video/data lines. These units are

designed to eliminate the effects of power line and

spurious noise potentials between ground points on

transmitted signals.
