Pin Function
Differential Signal Input: Each pin of this pair internally terminates with 50Ω to the VT pin.
Note that this input will default to an indeterminate state if left open.
See “Input Interface Applications” section.
Input Termination Center-Tap: Each input terminates to this pin. The VT pin provides a
center-tap for each input (IN, /IN) to a termination network for maximum interface
flexibility. See “Input Interface Applications” section.
Select Input: TTL/CMOS select input control that selects inputs IN0, or IN1. Note that this
input is internally connected to a 25kΩ pull-up resistor and will default to a logic High
state if left open.
Ground. Exposed pad must be connected to a ground plane that is the same potential as
the device ground pin.
Positive Power Supply: Bypass with 0.1µF0.01µF low ESR capacitors as close to the
pins as possible.
CML Differential Output Pairs: Differential buffered output copy of the selected input
signal. The CML output swing is typically 400mV across 100Ω. Unused output pairs may
be left floating with no impact on jitter. See “CML Output Termination” section.
