Pin Description
Pin Number
Pin Name
Pin Function
1, 4
IN, /IN
Differential Input: This input pair is the differential signal input to the device. Input
accepts DC-coupled differential signals as small as 100mV (200mVpp). Each pin of
this pair internally terminates with 50Ω to the VT pin. If the input swing falls below
a certain threshold (typical 30mV), the Fail Safe Input (FSI) feature will guarantee a
stable output by latching the output to its last valid state. See “Input Interface
Applications” subsection.
2
VT
Input Termination Center-Tap: Each input terminates to this pin. The VT pin
provides a center-tap for each input (IN, /IN) to a termination network for maximum
interface flexibility. See “Input Interface Applications” subsection.
4
VREF-AC
Reference Voltage: This output biases to VCC–1.2V. It is used for AC-coupling
inputs IN and /IN. Connect VREF-AC directly to the corresponding VT pin. Bypass
with 0.01F low ESR capacitor to VCC. Maximum sink/source current is ±1.5mA.
See “Input Interface Applications” subsection.
5, 8,13, 16
VCC
Positive Power Supply: Bypass with 0.1uF//0.01uF low ESR capacitors as close to
the VCC pins as possible.
6, 7, 14, 15
GND,
Exposed pad
Ground: Exposed pad must be connected to a ground plane that is the same
potential as the ground pins.

LVPECL Differential Output Pairs: Differential buffered copies of the input signal.
The output swing is typically 800mV. Unused output pair may be left floating with
no impact on jitter. See “LVPECL Output Termination” subsection.
