Pin Function
20, 18,
IN0, /IN0,
Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs
16, 14,
IN1, /IN1,
accept AC or DC-coupled signals as small as 100mV. Each pin of a pair internally terminates
13, 11,
IN2, /IN2,
to a VT pin through 50ohms. Note that these inputs will default to an indeterminate state if left
9, 7,
IN3, /IN3,
open.Please refer to the “Input Interface Applications” section for more details.

Input Termination Center-Tap: Each side of the differential input pair terminates to a VT pin.
12, 8,
VT2, VT3,
The VT pins provide a center-tap to a termination network for maximum interface flexibility.
4, 44,
VT4, VT5,
See “Input Interface Applications” section for more details. For a CML or LVDS inputs, the VT
41, 37
VT6, VT7
pin is left floating.
17,
VREF-AC0,
Reference Voltage: This output biases to VCC–1.2V. It is used when AC coupling the inputs
10,
VREF-AC1,
(IN, /IN). For AC-coupled applications, connect VREF_AC to the VT pin and bypass with a
2
VREF-AC2,
0.01μF low ESR capacitor to VCC. See “Input Interface Applications” section for more details.
39
VREF-AC3
21,
SEL0,
The single-ended TTL/CMOS-compatible inputs select the inputs to the multiplexer. Note that
22,
SEL1,
this input is internally connected to a 25kohms pull-up resistor and will default to a logic HIGH
35
SEL2
state if left open.
24, 27, 29, 32
VCC
Positive Power Supply. Bypass with 0.1μF
//0.01μF low ESR capacitors as close to each VCC
pin.
25, 26,
Q0,/Q0,
Differential Outputs: These LVPECL output pairs are the outputs of the device. Unused output
30, 31
Q1,/Q1
pairs may be left open. Each output is designed to drive 800mV into 50ohms terminated to
VCC–2V.(or VCC–1.2V if AC-coupled).
23, 28, 33
GND,
Ground. GND and exposed pad must both be connected to the most negative potential of chip
