Pin Description
PIN NAME FUNCTION
1 HAP Noninverting Input from Host Channel A
2 HAM Inverting Input from Host Channel A
3, 13, 17, 19 GND Ground
4 HBM Inverting Output to Host Channel B
5 HBP Noninverting Output to Host Channel B
6, 10, 16, 20 V
CC
Positive Supply Voltage Input. Bypass V
CC
to GND with 0.1FF and 0.001FF capacitors in parallel
and as close as possible to the device.
7 EN
Active-High Enable Input. Drive EN low to put device in standby mode. Drive EN high for normal
operation. EN is internally pulled down with a 330kI (typ) resistor.
8 BB
Channel-B Boost Enable Input. Drive BB high to enable channel-B output boost. Drive BB low for
standard SATA output level. BB is internally pulled down with a 330kI (typ) resistor.
9 BA
Channel-A Boost Enable Input. Drive BA high to enable channel-A output boost. Drive BA low for
standard SATA output level. BA is internally pulled down with a 330kI (typ) resistor.
11 DBP Noninverting Input from Device Channel B
12 DBM Inverting Input from Device Channel B
14 DAM Inverting Output to Device Channel A
15 DAP Noninverting Output to Device Channel A
18
CAD
Active-Low Cable-Detect Input. Drive CAD high to put device in standby mode. Drive CAD low for
normal operation. CAD is internally pulled up with a 330kI (typ) resistor.
— EP
Exposed Pad. Internally connected to GND. EP must be electrically connected to a ground plane
for proper thermal and electrical operation.
