description (continued)
The LPS input is considered inactive if it remains low for more than the LPS_RESET time (see the LPS terminal
definition) and is considered active otherwise. When the TSB41BA3A detects that the LPS input is inactive, the
PHY-LLC interface is placed into a low-power reset state in which the CTL and D outputs are held in the logic
0 state and the LREQ input is ignored; however, the PCLK output remains active. If the LPS input remains low
for more than the LPS_DISABLE time (see the LPS terminal definition), then the PHY-LLC interface is put into
a low-power disabled state in which the PCLK output is also held inactive. The TSB41BA3A continues the
necessary repeater functions required for normal network operation regardless of the state of the PHY-LLC
interface. When the interface is in the reset or disabled state and the LPS input is again observed active, the
PHY initializes the interface and returns to normal operation. The PHY-LLC interface is also held in the disabled
state during hardware reset. When the LPS terminal is returned to an active state after being sensed as having
entered the LPS_DISABLE time, the TSB41BA3A issues a bus reset. This broadcasts the node self-ID packet,
which contains the updated L bit state (the PHY LLC now being accessible).
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 described
above, 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
μ
s or until both the LPS is active and the LCtrl bit is 1.
