Input Fail-Safe
The differential inputs of the MAX9152 do not have
internal fail-safe biasing. If fail-safe biasing is required,
it can be implemented with external large-value resis-
tors. IN_+ should be pulled up to VCC with 10k
and
IN_ should be pulled down to GND with 10k
. The volt-
age-divider formed by the 10k
resistors and the 100
termination resistor (across IN_+ and IN_-) provides a
slight positive differential bias and sets a high state at
the device output when inputs are undriven.
Output Resistance
The MAX9152 has a selectable differential output resis-
tance to reduce reflections from impedance discontinu-
ities in the interconnect. Reflections are reduced,
compared to a high-impedance output. A termination
resistor at the receiver is still required and is the primary
termination for the interconnect. Select the output resis-
tance that best matches the differential characteristic
impedance of the interconnect used.
Select Function
The SEL0 and SEL1 logic inputs allow the device to be
configured as a high-speed differential crosspoint, 2:1
mux, 1:2 demux, dual repeater, or 1:2 splitter (Figure
8). See Table 1 for mode selection settings.
Enable Function
The EN0 and EN1 logic inputs enable and disable dri-
ver outputs OUT0 and OUT1. Setting EN0 or EN1 high
enables the corresponding driver output. Setting EN0
