Pin Function
Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs
accept AC- or DC-coupled differential signals as small as 100mV. Each pin of a pair internally
terminates to a VT pin through 50ý. Note that these inputs will default to an indeterminate
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 VT
pin. Each VT pin provides a center-tap to a termination network for maximum interface
flexibility. See “Input Interface Applications” section for more details.
Bank A, Bank B Input Channel Select (TTL/CMOS): These TTL/CMOS-compatible inputs
select the inputs to the multiplexers. 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
Reference Output Voltage: These outputs bias to V
AC-coupling the data inputs. Bypass with 0.01µF low ESR capacitor to V
Maximum current source or sink is 0.5mA. See “Input Interface Applications” section.
Positive Power Supply: Bypass with 0.1µF™ℑ0.01µF low ESR capacitors.

logic operation.
Ground: Ground pins and exposed pad must be connected to the same ground plane.
Not connected.
