Power
Chip Enable "high" provides normal operation. "Low" for power down mode.
With internal 50K-Ohm pull-up resistor.
Channel Select "high" selects path A. "Low" selects path B. With internal 50K-
Ohm pull-up resistor.
Selection pin for equalizer of Fin. "Low" means 2.5dB, "high" means 6.5dB. With
internal 50K-Ohm pull-up resistor.
CML input channel F with internal 50-Ohm pull down.
Channel Fin Signal detector output. Provides "high" when a signal is detected.
"High" means FA_OUT operates to the SATA i/m standard. "Low" means FA_
OUT support SATAx standard. With internal 50K-Ohm pull-up resistor.
CML output channel FA with internal 50-Ohm pull up.
"High" means FB_OUT operates to the SATA i/m standard. "Low" means FB_
OUT support SATAx standard. With internal 50K-Ohm pull-up resistor.
CML output channel FB with internal 50-Ohm pull up.
Supply ground.
"High" means Rout operates to the SATA i/m standard. "Low" means Rout sup-
port SATAx standard. With internal 50K-Ohm pull-up resistor.
Selection pin for equalizer of RA_IN. "Low" means 2.5dB, "high" means 6.5dB.
With internal 50K-Ohm pull-up resistor.
CML input channel RA with internal 50-Ohm pull down.
Signal detector for Channel RA_IN. Provides "high" when signal is detected.
Selection pin for equalizer of RB_IN. "Low" means 2.5dB, "high" means 6.5dB.
With internal 50K-Ohm pull-up resistor.
CML input channel RB with internal 50-Ohm pull down.
Signal detector for Channel RB_IN. Provides "high" when signal is detected.
CML output channel R with internal 50-Ohm pull up.
