Pin Function
Differential Input: Each pair accepts AC- or DC-coupled signals as small as 100mV.
Each pin of a pair internally terminates to a V
inputs will default to an indeterminate state if left open. If an input is not used, connect one
end of the differential pair to ground through a 1kΩ resistor, and leave the other end to
V
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 V
pin. The V
interface flexibility. See “Input Interface Applications” section for more details.
This Single-Ended TTL/CMOS compatible input selects the inputs to the multiplexer. Note
that this input is internally connected to a 25kΩ pull-up resistor and will default to a logic
HIGH state if left open. Input logic threshold is V
No Connect.
Positive Power Supply: Bypass with 0.1µF0.01µF low ESR capacitors.
Differential Outputs: These 100k compatible (internally temperature compensated)
LVPECL output pairs are copies of the selected input. Unused output pairs may be left
floating. See “Output Interface” for termination guidelines.
Ground. Ground pin and exposed pad must be connected to the same ground plane.
Reference Voltage: This reference output is equivalent to V
AC-coupled inputs. When interfacing to AC input signals, connect V
