V
CC
Positive Supply Voltage Input. Bypass V
CC
to GND with 1µF and 0.01µF capacitors in
parallel as close as possible to the device.
7 EN
Active-High Enable Input. Drive EN low to
put the device in standby mode. Drive EN
high for normal operation. EN has a 390kΩ
(typ) pulldown resistor.
8 PB
Channel B Preemphasis-Enable Input.
Drive PB high to enable channel B output
preemphasis. Drive PB low for standard
SATA output level. PB has a 390kΩ (typ)
pulldown resistor.
PIN NAME FUNCTION
9 PA
Channel A Preemphasis-Enable Input.
Drive PA high to enable channel A output
preemphasis. Drive PA low for standard
SATA output level. PA has a 390kΩ (typ)
pulldown resistor.
11 BINP Noninverting Input, Channel B
12 BINM Inverting Input, Channel B
14 AOUTM Inverting Output, Channel A
15 AOUTP Noninverting Output, Channel A
18 CAD
Active-Low Cable-Detect Input. For external
SATA applications, drive CAD high to put
the device in standby mode. Drive CAD low
for normal operation. CAD has a 390kI
(typ) pullup resistor. For internal SATA
applications, connect CAD to ground.
19 MODE
OOB Threshold Level Set. MODE has a
390kΩ (typ) pulldown resistor.
— EP
Exposed Pad. Internally connected to
GND. EP must be electrically connected
to a ground plane for proper thermal and
electrical operation.
