The GTY/GTYP transceivers support a range of power-down modes. These modes support both generic power management capabilities as well as those defined in the PCI Express® and SATA standards.
The GTY/GTYP transceivers offer different levels of power control. Each channel in each direction can be powered down separately using CH*_TXPD and CH*_RXPD. The HSCLK*_RPLLPD port directly affects the RPLL while the HSCLK*_LCPLLPD port directly affects the LCPLL.
