4, 2, 32,
IN0, /IN0,
Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs
30, 27, 25, 23, 21
IN1, /IN1,
accept AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally
IN2, /IN2,
terminates to a VT pin through 50. Note that these inputs will default to an indeterminate
IN3, /IN3
state if left open. Unused differential input pairs can be terminated by connecting one input
to VCC and the complementary input to GND through a 1k resistor. The VT pin is to be
left open in this configuration. Please refer to the “Input Interface Applications” section for
more details.
3, 31, 26, 22
VT0, VT1,
Input Termination Center-Tap: Each side of the differential input pair, terminates to a VT
VT2, VT3
pin. The V
T0, VT1, VT2, VT3 pins provide a center-tap to a termination network for
maximum interface flexibility. See “Input Interface Applications” section for more details.
6, 19
SEL0, SEL1
These single-ended TTL/CMOS compatible inputs select the inputs to the multiplexers.
Note that these inputs are internally connected to a 25k pull-up resistor and will default
to a logic HIGH state if left open. Input switching threshold is VCC/2.
1, 5, 8,
VCC
Positive Power Supply: Bypass with 0.1F||0.01F low ESR capacitors. The 0.01F
17, 20, 24, 28, 29
capacitor should be as close to a V
CC pin as possible.
10, 11
Q, /Q
Differential Outputs: This LVDS output pair is the output of the device. It is a
logic function of the IN0, IN1, IN0, IN1 and SEL0 inputs. Please refer to the “Truth Table’”
for details.
7, 9, 12, 13, 16, 18
GND,
Ground: Ground pin and exposed pad must be connected to the same ground plane.
Exposed pad
14, 15
NC
No connect (unused pins).
