Pin Description (continued)

NAME

FUNCTION

ENA0

Channel A0 Output Enable. Drive ENA0 high to enable the A0 LVDS outputs. An internal 435k

Ω resistor

to GND pulls ENA0 low when unconnected.

OUTA0

Channel A0 LVDS Inverting Output. Connect a 100

Ω termination resistor between OUTA0 and OUTA0 at

the receiver inputs to ensure proper operation.

OUTA0

Channel A0 LVDS Noninverting Output. Connect a 100

Ω termination resistor between OUTA0 and

OUTA0 at the receiver inputs to ensure proper operation.

INA

LVDS/HSTL (MAX9394) or LVPECL/CML (MAX9395) Noninverting Input. An internal 128k

Ω pullup

resistor to VCC pulls the input high when unconnected (MAX9394). An internal 68k

Ω resistor to GND

pulls the input low when unconnected (MAX9395).

INA

LVDS/HSTL (MAX9394) or LVPECL/CML (MAX9395) Inverting Input. An internal 128k

Ω pullup resistor to

VCC pulls the input high when unconnected (MAX9394). An internal 68k

Ω resistor to GND pulls the input

low when unconnected (MAX9395).

LB_SELA

Loopback Select for Channel A Output. Connect LB_SELA to GND or leave unconnected to reproduce

the INA (INA) differential inputs at OUTA_ (OUTA_). Connect LB_SELA to VCC to loop back the INB_

(INB_) differential inputs to OUTA_ (OUTA_). An internal 435k

Ω resistor to GND pulls LB_SELA low when

unconnected.
