MAX3982
Applications Information
Autodetect
The MAX3982 can automatically detect an incoming
signal and enable the data outputs. Autodetect can be
accomplished by connecting the LOS pin to TX_DIS-
ABLE. TX_DISABLE has a 10k
Ω internal pullup resistor.
If a loss-of-signal is detected, the TX_DISABLE pin is
forced high and disables the outputs. Leaving the
inputs to the MAX3982 open (i.e., floating) is not recom-
mended as noise amplification may occur and create
undesirable output signals. Autodetect is recommend-
ed to eliminate noise amplification or possible oscilla-
tion. For periods much greater than 100ns without data
transitions, autodetect disables the output.
Layout Considerations
Circuit board layout and design can significantly affect
the performance of the MAX3982. Use good high-fre-
quency design techniques, including minimizing ground
inductance and using controlled-impedance transmis-
sion lines on the data signals. Power-supply decoupling
should also be placed as close to the VCC pins as possi-
ble. This should be sufficient supply filtering. Always con-
nect all VCC pins to a power plane. Take care to isolate
the input from the output signals to reduce feedthrough.
Exposed Pad Package
The exposed-pad, 16-pin QFN package incorporates
features that provide a very low thermal resistance path
for heat removal from the IC. The exposed pad on the
MAX3982 must be soldered to the circuit board for
proper thermal performance. For more information on
exposed-pad packages, refer to Maxim Application
Note HFAN-08.1: Thermal Considerations of QFN and
Other Exposed-Paddle Packages.
