I/O

DESCRIPTION

NAME

NO.

DE2

I, CMOS

Sets the output de-emphasis for Channel 2. 3-state input with integrated pull-up and pull-

down resistors.

DE2 = Low = 0 dB

DE2 = Mid = -3.5 dB

DE2 = High = -6.2 dB

OS2

I, CMOS

Sets the output swing (differential voltage amplitude) for Channel 2. 2-state input with an

integrated pull down resistor.

OS2 = Low = 0.9 mV

OS2 = High = 1.1 mV

EN_RXD

I, CMOS

Enable. The device has a 660-kΩ pulldown resistor. Device is active when EN_RXD = High.

Drive actively high or install a pullup resistor (recommend 4.7 KΩ) for normal operation.

Does reset state machine.

RSV

I, CMOS

Reserved. Can be left as no-connect.

VCC

1, 13

Positive power supply. Power supply is 3.3 V.

GND

10, 21, PAD

Ground. PAD must be connected to Ground. Pins 10, 21 can be connected to Ground or left

unconnected.

6, 7, 18, 24

—

No connection. These pins can be tied to any desired voltages including connecting them to

GND.
