DRIVER_SEL1
[3:0]
O
DRIVER_SEL1: Used to select RS-232/ RS-424/ 4-Wire RS-485/
2-Wire RS-458 Serial Port Mode for UART 1.
Driver Equalization Level Control (DEQ[0]): During system
initialization, DRIVER_SEL1[3] acts as the DEQ[0] pin, and it is
used to control the driver current level. By default, it is set to ‘0’
without pin strapped.
Driver Current Level Control (DTX[3:1]): During system
initialization, DRIVER_SEL1[2:0] acts as the DTX[3:1] pins, and
they are used to control the driver current level. By default, they are
set to ‘000’ without pin strapped.

PCI Express Serial Input Signal: Differential PCI Express input
signals.

I
Reference Input Clock: Connects to external 100MHz differential
clock
The input clock signals must be delivered to the clock buffer cell
through an AC-coupled interface so that only the AC information of
the clock is received, converted, and buffered. It is recommended
that a 0.1uF be used in the AC-coupling.
29
RREF
I
Reference Resistor: To accurately set internal bias references, a
precision resistor must be connected between Rref and Vss. The
resistor should have a nominal value of 2.1 K and accuracy of +/-
1%
