Pin Name
Pin Description
LOOPBACK Mode Control. TTL/CMOS control input. LOOPBACK is an active HIGH signal
used to control the LOOPBACK MUX. LOOPBACK is internally connected to a 25k
Ω
pull-
down resistor and will default to a LOW state if left open. V
TH
= V
CC
/2.
Receiver Output Control. TTL/CMOS control input. /RXEN is an active LOW signal used to
enable the receiver outputs. /RXEN is internally connected to a 25k
Ω
pull-down resistor and will
default to a LOW state if left open. V
TH
= V
CC
/2.

/RXEN
1, 2
RXIN, /RXIN
Receiver Differential Input. Input accepts AC differential signals as small as 10mV (20mV
PP
).
Each pin internally terminates to V
CC_RXIN
-1.3V (internal voltage reference) through 50
Ω
. Input
will default to an indeterminate state if left open. See figure 6b.

/TXEN
Transmitter Output Control. TTL/CMOS control input. /TXEN is an active LOW signal used to
enable the transmitter output. /TXEN is internally connected to a 25k
Ω
pull-down resistor and
will default to a LOW state if left open. V
TH
= V
CC
/2.
14, 13
TXIN, /TXIN
Transmitter Differential Input. Input accepts AC- or DC-coupled differential signals as small as
100mV (200mV
PP
). Each pin terminates to the TXVT
pin through 50
Ω
. Note that this input will
default to an indeterminate state if left open. See figure 6a.

TXVCTRL
Transmitter Output Swing Control. Input that controls the output amplitude of the transmitter.
The operating range of the control input is from V
REF_CTRL
(max swing) to V
CC
(min swing).
Control of the output swing can be obtained by using a variable resistor between V
REF_CTRL
and
V
CC_TXQ
through a wiper driving TXVCTRL. Setting TXVCTRL to V
CC_TXQ
sets the output swing
to min swing. Refer to the “Interface Applications” and “Output Stage” sections for more
details.
Input Termination Center-Tap. Each side of the transmitter differential input pair terminates to
the TXVT
pin. The TXVT
pin provides a center-tap to a termination network for maximum
interface flexibility. Refer to the “Input Stage” section for more details.
