PIN

NAME

FUNCTION

17

ENA1

A1 Output Enable. Drive ENA1 high to enable the A1 LVDS outputs. An internal 435k

Ω resistor pulls ENA1 low

when unconnected.

18

OUTA1

A1 LVDS Inverting Output. Connect a 100

Ω termination resistor between OUTA1 and OUTA1 at the receiver

inputs to ensure proper operation.

19

OUTA1

A1 LVDS Noninverting Output. Connect a 100

Ω termination resistor between OUTA1 and OUTA1 at the receiver

inputs to ensure proper operation.

21

ENA0

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

Ω resistor pulls ENA0 low

when unconnected.

22

OUTA0

A0 LVDS Inverting Output. Connect a 100

Ω termination resistor between OUTA0 and OUTA0 at the receiver

inputs to ensure proper operation.

23

OUTA0

A0 LVDS Noninverting Output. Connect a 100

Ω termination resistor between OUTA0 and OUTA0 at the receiver

inputs to ensure proper operation.

26

INA0

LVDS/HSTL (MAX9392) or LVPECL/CML (MAX9393) Noninverting Input. An internal 128k

Ω resistor to V

CC

pulls

the input high when unconnected (MAX9392). An internal 68k

Ω resistor to GND pulls the input low when

unconnected (MAX9393).

27

INA0

LVDS/HSTL (MAX9392) or LVPECL/CML (MAX9393) Inverting Input. An internal 128k

Ω resistor to V

CC

pulls the

input high when unconnected (MAX9392). An internal 68k

Ω resistor to GND pulls the input low when

unconnected (MAX9393).

28

ASEL0

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

CC

to select the INA1

(

INA1) set of inputs. An internal 435k

Ω resistor pulls ASEL0 low when unconnected.

30

INA1

LVDS/HSTL (MAX9392) or LVPECL/CML (MAX9393) Noninverting Input. An internal 128k

Ω resistor to V

CC

pulls

the input high when unconnected (MAX9392). An internal 68k

Ω resistor to GND pulls the input low when

unconnected (MAX9393).

31

INA1

LVDS/HSTL (MAX9392) or LVPECL/CML (MAX9393) Inverting Input. An internal 128k

Ω resistor to V

CC

pulls the

input high when unconnected (MAX9392). An internal 68k

Ω resistor to GND pulls the input low when

unconnected (MAX9393).

32

ASEL1

Input Select for A1 Output. Selects the differential input to reproduce at the A1 differential outputs. Connect
ASEL1 to GND or leave open to select the INA0 (

INA0) set of inputs. Connect ASEL1 to V

CC

to select the INA1

(

INA1) set of inputs. An internal 435k

Ω resistor pulls ASEL1 low when unconnected.

EP

Exposed Paddle (QFN Package Only). Connect to GND for optimal thermal and EMI characteristics.
