Pin Function
Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs
accept AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally
terminates to a V
state if left open. Unused differential input pairs can be terminated by connecting one input
to V
left open in this configuration. 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
maximum interface flexibility. See “Input Interface Applications” section for more details.
These single-ended TTL/CMOS-compatible inputs select the inputs to the multiplexers.
Note that these inputs are internally connected to a 25ký pull-up resistor and will default
to a logic HIGH state if left open. Input switching threshold is V
Positive Power Supply: Bypass with 0.1µF•‚0.01µF low ESR capacitors.
Differential Outputs: These LVDS output pairs are the outputs of the device. They are a
logic function of the INA0, INA1, INB0, INB1 and SELA and SELB inputs. Please refer to
the “Truth Table’” for details. If an output is not used, it must be terminated with 100ý
across the differential pair.
Ground: Ground pin and exposed pad must be connected to the same ground plane.
