Description
Chip Enable "high" provides normal operation. "Low" for power down mode.
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.
F-Channel external SATA. When logic 1, operates to the SATA i/m standard.
When low, operates to SATAx/SAS. With internal 50K-ohm pull-up resistor.
Channel Fin Signal detector output. Provides "high" when a signal is detected.
CML output channel F with internal 50-Ohm pull up.
