Pin Function
Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs
accept AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally
terminates to a V
state if left open. Unused differential input pairs can be terminated by connecting one input
to V
left open in this configuration. Please refer to the “Input Interface Applications” section for
more details.
Input Termination Center-Tap: Each side of the differential input pair, terminates to a V
pin. The V
maximum interface flexibility. See “Input Interface Applications” section for more details.
These single-ended TTL/CMOS compatible inputs select the inputs to the multiplexers.
Note that these inputs are internally connected to a 25kΩ pull-up resistor and will default
to a logic HIGH state if left open. Input switching threshold is V
Positive Power Supply: Bypass with 0.1µF||0.01µF low ESR capacitors. The 0.01µF
capacitor should be as close to a V
Differential Outputs: This LVDS output pair is the output of the device. It is a
logic function of the IN0, IN1, IN0, IN1 and SEL0 inputs. Please refer to the “Truth Table’”
for details.
Ground: Ground pin and exposed pad must be connected to the same ground plane.
No connect (unused pins).
