SATA Low voltage differential signal for SATA
TMDS HDMI Transition minimized differential signal for HDMI displays
USB DC coupled differential signalling for traditional (non-Superspeed) USB signals
USB SS Differential signal for SuperSpeed USB signals
USB VBUS 5V 5V tolerant input for USB VBUS detection
VDD_IN Main power source from Carrier to Module
3.3V 3.3V power domain: Active while CARRIER_PWRON is high and CARRIER_SBY# is NOT active (i.e. both signals are high)
1.8V 1.8V power domain: Active while CARRIER_PWRON is high and CARRIER_SBY# is NOT active (i.e. both signals are high)
3.3Vsb 3.3V standby power domain: Active while CARRIER_PWRON is high (regardless of CARRIER_SBY#)
1.8Vsb 1.8V standby power domain: Active while CARRIER_PWRON is high (regardless of CARRIER_SBY#)
Sleep Module is in its lowest power state
Runtime Module is full on. CARRIER_PWRON is high and CARRIER_SBY# is NOT active (i.e. both signals are high)
Standby Module is in standby state or higher
