Differential Input: These input pairs are the differential signal inputs to the device. These inputs
accept AC- or DC-coupled signals as small as 100mV (200mVp-p). Each pin of a pair internally
terminates to a VT pin through 50
Ω. Note that these inputs will default to an indeterminate state if
left open. Please refer to the “Input Interface Applications” section for more details.
2, 6
VT0, VT1
Input Termination Center-Tap: Each side of the differential input pair terminates to a VT pin. The
VT0 and VTI pins provide a center-tap to a termination network for maximum interface flexibility.
See the “Input Interface Applications” section for more details.
31
SEL
This single-ended TTL/CMOS-compatible input selects the inputs to the multiplexer. Note that this
input is internally connected to a 25k
Ω pull-up resistor and will default to logic HIGH state if left
open. The MUX select switchover function is asynchronous.

NC
No connect.

VCC
Positive Power Supply: Bypass with 0.1F//0.01F low ESR capacitors as close to VCC pins as
possible.

Differential Outputs: These 100k (temperature compensated) LVPECL output pairs are low skew
copies of the selected input. Unused output pins may be left floating. Please refer to the “LVPECL
” section for details.

GND,
Exposed Pad
Ground: Ground pins and exposed pad must be connected to the same ground plane.

VREF-AC0
VREF-AC1
Reference Voltage: This output biases to VCC – 1.2V. It is used for AC-coupling inputs (IN, /IN).
Connect VREF_AC directly to the VT pin. Bypass with 0.01F low ESR capacitor to VCC. See the
“Input Interface Applications” section. Maximum sink/source current is ±1.5mA. Due to the limited
drive capability use for input at the same package only.
