LOOPBACK
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
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
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
. Input
will default to an indeterminate state if RXIN inputs are 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
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
. Input will default to an
indeterminate state if TXIN inputs are left open. See figure 6a.
9
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 is obtained with 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.
11
TXVT
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.
