TERMINAL NAME

I/O, TYPE

TERMINAL DESCRIPTION

NUMBER

DEMA0, DEMA1

49, 50

I, 4-LEVEL,

DEMA[1:0] controls the CHA output amplitude. The Terminals are

LVCMOS

defined as DEMA[1:0] only when ENSMB is de-asserted (low). Each of

the 4 A channels have the same level unless controlled by the SMBus

control registers. When ENSMB goes high the SMBus registers provide

independent control of each lane and the DEMA[1:0] Terminals are

converted to SCL and SDA. See Table 7.

SD_TH

26

I, 4-LEVEL,

Controls the internal Signal Detect Threshold on the INB-OUTB

LVCMOS

Channels. For CHB, the signal detect is used to bring the output into and

out of IDLE. This allows the OOB signaling to pass with minimal

distortion.

See Table 3.

CONTROL TERMINALS — BOTH TERMINAL AND SMBus MODES (LVCMOS)

RXDET

22

I, 4-LEVEL,

The RXDET Terminal controls the receiver detect function. Depending on

LVCMOS

the input level, a 50

Ω or >50KΩ termination to the power rail is enabled.

In SAS/SATA system RXDET should be set to a Logic "1" state to keep

the termination always enabled.

See Table 2.

I, 4-LEVEL,

Reserved:

LVCMOS

This input must be left Floating.

VDD_SEL

I, FLOAT

Controls the internal regulator

Float = 2.5V mode

Tie GND = 3.3V mode

PWDN

52

I, LVCMOS

Tie High = Low power - power down

Tie GND = Normal Operation

See Table 2.
