No Connection. Not internally connected.
Ground
Channel B Output Enable. Drive ENB high to enable the LVDS outputs for channel B. An internal 435kΩ
resistor to GND pulls ENB low when unconnected.
Channel B LVDS Noninverting Output. Connect a 100Ω termination resistor between OUTB and OUTB at
the receiver inputs to ensure proper operation.
Channel B LVDS Inverting Output. Connect a 100Ω termination resistor between OUTB and OUTB at the
receiver inputs to ensure proper operation.
Power-Supply Input. Bypass each V
bypass capacitors as close to the device as possible, with the 0.01µF capacitor closest to the device.
LVDS/HSTL (MAX9394) or LVPECL/CML (MAX9395) Inverting Input. An internal 128kΩ pullup resistor to
V
low when unconnected (MAX9395).
LVDS/HSTL (MAX9394) or LVPECL/CML (MAX9395) Noninverting Input. An internal 128kΩ pullup
resistor to V
pulls the input low when unconnected (MAX9395).
Loopback Select for Channel B Output. Connect LB_SELB to GND or leave unconnected to reproduce
the INB_ (INB_) differential inputs at OUTB (OUTB). Connect LB_SELB to V
differential inputs to OUTB (OUTB). An internal 435kΩ resistor to GND pulls LB_SELB low when
unconnected.
LVDS/HSTL (MAX9394) or LVPECL/CML (MAX9395) Inverting Input. An internal 128kΩ pullup resistor to
V
low when unconnected (MAX9395).
LVDS/HSTL (MAX9394) or LVPECL/CML (MAX9395) Noninverting Input. An internal 128kΩ pullup
resistor to V
pulls the input low when unconnected (MAX9395).
Channel B Multiplexer Control Input. Selects the differential input to reproduce at the B channel
differential output. Connect BSEL to GND or leave unconnected to select the INB0 (INB0) set of inputs.
Connect BSEL to V
BSEL low when unconnected.
Channel A1 Output Enable. Drive ENA1 high to enable the A1 LVDS outputs. An internal 435kΩ resistor
to GND pulls the ENA1 low when unconnected.
Channel A1 LVDS Inverting Output. Connect a 100Ω termination resistor between OUTA1 and OUTA1 at
the receiver inputs to ensure proper operation.
Channel A1 LVDS Noninverting Output. Connect a 100Ω termination resistor between OUTA1 and
OUTA1 at the receiver inputs to ensure proper operation.
