ICLK

Single-ended clock reference input pin

LVDS1

LVDS1 input pin

SRL

Slew Rate Limited output

VIS

Variable voltage Schmitt-triggered input

70 kΩ (typical) internal pull-up. Unless otherwise noted in the pin description, internal pull-ups

are always enabled.

Note:

Internal pull-up resistors prevent unconnected inputs from floating. Do not rely on

internal resistors to drive signals external to the device. When connected to a load

that must be pulled high, an external resistor must be added.

70 kΩ (typical) internal pull-down. Unless otherwise noted in the pin description, internal pull-

downs are always enabled.

Note:

Internal pull-down resistors prevent unconnected inputs from floating. Do not rely on

internal resistors to drive signals external to the device. When connected to a load

that must be pulled low, an external resistor must be added.

Power pin

Note:

Digital signals are not 5V tolerant unless specified.
