DESCRIPTION

PULLDOWN

NAME

NO.

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 图 2 for details of timing. Refer to 表 3 for VOD linearity range

and DC gain options.

PU (approx 45K)

PD (approx 95K)

CFG1

I (4-level)

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 图 2 for details of timing. Refer to 表 3 for VOD linearity range and

DC gain options.

PU (approx 45K)

PD (approx 95K)

CFG2

I (4-level)

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 图 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.

PU (approx 45 K)

PD (approx 95K)

MODE

I (4-level)

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

Recommend leaving this pin unconnected on PCB.

RSVD1

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

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

DCBOOST#

I (2-level)

PU (approx 400 K)

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