NAME
FUNCTION
A1 Output Enable. Drive ENA1 high to enable the A1 LVDS outputs. An internal 435kΩ resistor pulls ENA1 low
when unconnected.

ENA1
A1 LVDS Inverting Output. Connect a 100Ω termination resistor between OUTA1 and OUTA1 at the receiver
inputs to ensure proper operation.

ENA0
A1 LVDS Noninverting Output. Connect a 100Ω termination resistor between OUTA1 and OUTA1 at the receiver
inputs to ensure proper operation.
A0 Output Enable. Drive ENA0 high to enable the A0 LVDS outputs. An internal 435kΩ resistor pulls ENA0 low
when unconnected.
A0 LVDS Inverting Output. Connect a 100Ω termination resistor between OUTA0 and OUTA0 at the receiver
inputs to ensure proper operation.

unconnected (MAX9393).
Input Select for A0 Output. Selects the differential input to reproduce at the A0 differential outputs. Connect
ASEL0 to GND or leave open to select the INA0 (INA0) set of inputs. Connect ASEL0 to V
(INA1) set of inputs. An internal 435kΩ resistor pulls ASEL0 low when unconnected.
