OE0
OE1
LVTTL Input
OE0/OE1 enables OUT0/OUT1 when HIGH. When LOW, OUTx are
powered down and both OUT+ and OUT- float HIGH.

MUX
LVTTL Input
Selects Source for OUT, Selects Either IN0 (LOW) or IN1 (HIGH); defaults
HIGH when left open.
15
MUX1
LVTTL Input
Selects Source for OUT1. Selects Either IN (HIGH) or IN0 (LOW); defaults
HIGH when left open.
16
MUX0
LVTTL Input
Selects Source for OUT0. Selects either IN (LOW) or IN1 (HIGH); defaults
HIGH when left open.

VDDP1
Power Supply
3.3 V supply for LVPECL output drivers. VDDP is for OUT, VDDP0 is for
OUT0, and VDDP1 is for OUT1.
