low-power reset state in which the CTL and D outputs are held in the
1. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
Philips Semiconductors
The LPS input is considered inactive if it remains low for more than
2.6 s and is considered active otherwise. When the PDI1394P25
detects that LPS is inactive, it will place the PHY-LLC interface into a
logic zero state and the LREQ input is ignored; however, the
SYSCLK output remains active. If the LPS input remains low for
more than 26 s, the PHY-LLC interface is put into a low-power
disabled state in which the SYSCLK output is also held inactive. The
PHY-LLC interface is also held in the disabled state during hardware
reset. The PDI1394P25 will continue 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 LPS is again observed active, the PHY will
initialize the interface and return it to normal operation.
8.0 ABSOLUTE MAXIMUM RATINGS
In accordance with the Absolute Maximum Rating System (IEC 134). Voltages are referenced to GND (ground = 0 V).

CONDITION
CONDITION
The PHY uses the C/LKON terminal to notify the LLC to power up
and become active. When activated, the C/LKON signal is a square
wave of approximately 163 ns period. The PHY activates the
C/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 LCtrI 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 C/LKON output when the LLC becomes active
(both LPS active and the LCtrl bit set to 1). The PHY also deasserts
the C/LKON output when a bus-reset occurs unless a PHY interrupt
condition exists which would otherwise cause C/LKON to be active.
