DESCRIPTION

NAME

NO.

CFG1

4

I (4-level)

PU (approx 45K)

PD (approx 95K)

CFG1. This pin along with CFG2 will select VOD linearity range and DC gain

for both channels 1 and 2. The state of this pin is sampled after the rising edge

of EN. Refer to Figure 2 for details of timing. Refer to Table 3 for VOD linearity

range and DC gain options.

CFG2

15

I (4-level)

PU (approx 45K)

PD (approx 95K)

CFG2. This pin along with CFG1 will set VOD linearity range and DC gain for

both channels 1 and 2. The state of this pin is sampled after the rising edge of

EN. Refer to Figure 2 for details of timing. Refer to Table 3 for VOD linearity

range and DC gain options.

MODE

7

I (4-level)

PU (approx 45 K)

PD (approx 95K)

MODE. This pin is for selecting different modes of operation. The state of this

pin is sampled after the rising edge of EN. Refer to Figure 2 for details of

timing.

0 = Basic Redriver Mode.

R = PCIe / Test Mode. PCIe Mode and TI Internal use only

F = USB3.2 x1 Dual Channel Operation enabled (TUSB1002A normal mode).

1 = USB3.2 x1 Single-channel operation.

RSVD1

24

O

RSVD1. Under normal operation, this pin will be driven low by TUSB1002A.

Recommend leaving this pin unconnected on PCB.

DCBOOST#

14

I (2-level)

PU (approx 400 K)

DCBOOST#. This pin when asserted low will increase the DC Gain level

defined inTable 3 by +1 dB unless already at +2dB. If DC Gain level defined

inTable 3 is already at +2 dB, then asserting this pin low will not change the DC

Gain level. This pin can be left unconnected if this function is not needed.

1 = DC Gain defined by Table 3.

0 = DC Gain defined by Table 3 is increased by +1 dB.
