5 / 11 page www.ti.com TSB41BA3A SLLA224A – JUNE 2006 – REVISED OCTOBER 2006 The PHY uses the S5_LKON terminal to notify the LLC to power up and become active. When activated, the output S5_LKON signal is a square wave. The PHY activates the S5_LKON output when the LLC is inactive and a wake-up event occurs. The LLC is considered inactive when either the LPS input is inactive, as previously described, or the LCtrl bit is cleared to 0. A wake-up event occurs when a link-on PHY packet addressed to this node is received, or conditionally when a PHY interrupt occurs. The PHY deasserts the S5_LKON output when the LLC becomes active (both LPS sensed as active and the LCtrl bit set to 1). The PHY also deasserts the S5_LKON output when a bus reset occurs, unless a PHY interrupt condition exists which would otherwise cause S5_LKON to be active. If the PHY is power-cycled and the power class is 0 through 4, then the PHY asserts S5_LKON for approximately 167 µs or until both the LPS is active and the LCtrl bit is 1.
