Q1
LVDS Output
Noninverted IN output. Typically loaded with 100 W receiver termination
resistor across differential pair.

Q1
LVDS Output
Inverted IN output. Typically loaded with 100 W receiver termination resistor
across differential pair.

Q2
LVDS Output
Inverted IN output. Typically loaded with 100 W receiver termination resistor
across differential pair.

Q3
LVDS Output
Noninverted IN output. Typically loaded with 100 W receiver termination
resistor across differential pair.

Q3
LVDS Output
Inverted IN output. Typically loaded with 100 W receiver termination resistor
across differential pair.
7
VCC
Positive Supply Voltage.
8
EN
LVTTL / LVCMOS Input
Synchronous Output Enable. When LOW, Q outputs will go LOW and Qb
outputs will go HIGH on the next negative transition of IN input. The internal
DFF register is clocked on the falling edge of IN input; see Figure 26. The EN
pin has an internal pullup resistor and defaults HIGH when left open.

VREFAC
LVPECL Output
The VREFAC reference output can only be used to rebias capacitorcoupled
differential or singleended input signals. For the capacitorcoupled IN and/or
INb inputs, VREFAC should be connected to the VT pin and bypassed to ground
with a 0.01 mF capacitor.

Q0
LVDS Output
Noninverted IN output. Typically loaded with 100 W receiver termination
resistor across differential pair.
16
Q0
LVDS Output
Inverted IN output. Typically loaded with 100 W receiver termination resistor
across differential pair.
EP
The Exposed Pad (EP) on the QFN16 package bottom is thermally connected
to the die for improved heat transfer out of package. The exposed pad must be
attached to a heatsinking conduit. The pad is not electrically connected to the
die, but is recommended to be electrically and thermally connected to GND on
the PC board.
2. In the differential configuration, when the input termination pin (VT) is connected to a termination voltage or left open, and if no signal is applied
on IN/IN inputs, then the device will be susceptible to selfoscillation.
