LTC1518/LTC1519
Figure 9 shows a trace with 100ft category 5 UTP between
an LTC1685 driver and an LTC1518 receiver. Notice that at
the far end of the cable, the signal to the LTC1518 input has
been reduced. Figure 10 shows a 52Mbps square wave.
Output Short-Circuit Protection
The LTC1518/LTC1519 employ voltage sensing short-
circuit protection at the output terminals. For a given input
differential, this circuitry determines what the correct

output level should be. For example, if the input differential
is
≥
300mV, it expects the output to be a logic high. If the
output is subsequently shorted to a voltage below VDD/2,
this circuitry shuts off the output devices and turns on a
smaller device in its place. A timeout period of about 50ns
is used in order to maintain normal high frequency opera-
tion, even under heavy capacitive loads (>100mA tran-
sient current into the load).
