PIN

TYPE(1)

DESCRIPTION

NAME

NO.

RX2P

36

I

Non-inverting differential inputs to the equalizer. Integrated 50 Ω termination resistor

from the pin to internal CM bias voltage. Channel 2.

RX3N

40

I

Inverting differential inputs to the equalizer. Integrated 50 Ω termination resistor from

the pin to internal CM bias voltage. Channel 3.

RX3P

39

I

Non-inverting differential inputs to the equalizer. Integrated 50 Ω termination resistor

from the pin to internal CM bias voltage. Channel 3.

TX0N

19

O

Inverting pin for 100 Ω differential driver output. Channel 0.

TX0P

20

O

Non-inverting pin for 100 Ω differential driver output. Channel 0.

TX1N

16

O

Inverting pin for 100 Ω differential driver output. Channel 1.

TX1P

17

O

Non-inverting pin for 100 Ω differential driver output. Channel 1.

TX2N

12

O

Inverting pin for 100 Ω differential driver output. Channel 2.

TX2P

13

O

Non-inverting pin for 100 Ω differential driver output. Channel 2.

TX3N

9

O

Inverting pin for 100 Ω differential driver output. Channel 3.

TX3P

10

O

Non-inverting pin for 100 Ω differential driver output. Channel 3.

VCC

14, 15, 34, 35

P

Power supply pins. VCC = 3.3 V ±10%. The VCC pins on this device should be

connected through a low-resistance path to the board VCC plane. Install a decoupling

capacitor to GND near each VCC pin.
