PACKAGE/ORDERING INFORMATION
Pin Number
Pin Name
Pin Function
1, 4
IN, /IN
Differential Input: This input pair receives the signal to be buffered. Each pin is internally
terminated with 50Ω to the V
T pin. Note that this input will default to an indeterminate state
if left open. See “Input Interface Applications”section.
2
VT
Input Termination Center-Tap: Each input terminates to this pin. The V
T pin provides a
center-tap for each input (IN, /IN) to the termination network for maximum interface
exibility. See “Input Interface Applications”section.
3
VREF-AC
Reference Output Voltage: This output biases to V
CC –1.2V. It is used when AC-coupling
to differentail inputs. Connect V
REF-AC directly to the VT pin. Bypass with 0.01F low ESR
capacitor to V
CC. See “Input Interface Applications” section.
8, 13
VCC
Positive Power Supply: Bypass with 0.1F//0.01F low ESR capacitors as close to the
pins as possible. A 0.01F capacitor should be as close to the V
CC pin as possible.
5, 16
GND,
Ground. Exposed pad must be connected to a ground plane that is the same potential
Exposed Pad
as the ground pin.
14, 15
/Q0, Q0,
LVPECL Differential Output Pairs: Differential buffered output copy of the input signal. The
11, 12
/Q1, Q1,
output swing is typically 400mV. Proper termination is 50Ω to V
CC–2V at the receiving
9, 10
/Q2, Q2,
end. Unused output pairs may be left oating with no impact on jitter or skew.
