Inverting Output to Host Channel B. HBM must be capacitively coupled (see note).
Noninverting Output to Host Channel B. HBP must be capacitively coupled (see note).
Power-Supply Input. Bypass V
close to the device as possible; recommended for each V
Enable Input. Drive EN low for low-power standby mode. Drive EN high for normal operation. EN is
internally pulled down by a 70kI (typ) resistor.
Channel B Boost-Enable Input. Drive BB high to enable channel B +6dB output boost. Drive BB low
for standard SAS/SATA output level. BB is internally pulled down by a 70kI (typ) resistor.
Channel A Boost-Enable Input. Drive BA high to enable channel A +6dB output boost. Drive BA low
for standard SAS/SATA output level. BA is internally pulled down by a 70kI (typ) resistor.
Noninverting Input from Device Channel B. DBP must be capacitively coupled (see note).
Inverting Input from Device Channel B. DBM must be capacitively coupled (see note).
Inverting Output to Device Channel A. DAM must be capacitively coupled (see note).
Noninverting Output to Device Channel A. DAP must be capacatively coupled (see note).
OOB-Mode Logic Input. M is internally pulled down by a 70kI (typ) resistor. Drive M low or leave
unconnected for SATA OOB threshold. Drive M high for SAS OOB threshold.
Exposed Pad. Internally connected to GND. Connect to a large ground plane for proper thermal
and electrical operation. Not intended as an electrical connection point.
