Description
Input is 2.5 V, the ADDR_[3:0] pins set the SMBus address for the retimer.
These pins are strap inputs. Their state is read on power-up to set the SMBus
address in SMBus control mode.
High = 1KΩ to VDD, Low = 1KΩ to GND
Note that these pins are shared with the lock indicator functions. See Table 4

V_DD = 2.5 V ± 5%
Ground reference.
Power
Ground reference. The exposed pad at the center of the package must be
connected to ground plane of the board with at least 4 vias to lower the ground
impedance and improve the thermal performance of the package.

(1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or
other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating
Conditions indicate conditions at which the device is functional and the device should not be operated outside these conditions.
