description (continued)
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 initializes the interface and returns it
to normal operation.
When the PHY-LLC interface is in the low-power disabled state, the TSB41AB1 automatically enters a
low-power mode if the port is inactive (disconnected, disabled, or suspended). In this low-power mode, the
TSB41AB1 disables its internal clock generators and also disables various voltage and current reference
circuits depending on the state of the port (some reference circuitry must remain active in order to detect new
cable connections, disconnections, or incoming TPBIAS, for example). The lowest power consumption (the
ultralow-power sleep mode) is attained when the port is either disconnected, or disabled with the port interrupt
enable bit cleared. The TSB41AB1 exits the low-power mode when the LPS input is asserted high or when a
port event occurs which requires that the TSB41AB1 become active in order to respond to the event or to notify
the LLC of the event (for example, incoming bias is detected on a suspended port, a disconnection is detected
on a suspended port, a new connection is detected on a nondisabled port, etc.). The SYSCLK output becomes
active (and the PHY-LLC interface is initialized and becomes operative) within 7.3 ms after LPS is asserted high
when the TSB41AB1 is in the low-power mode.
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 LCtrl bit is cleared to 0. A wake-up event occurs when a link-on PHY packet
addressed to this node is received, or 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.

I
Up to 10 composite, 4 S-video, and 2 composite or 3 component video inputs (or a combination thereof)
can be supported.
The inputs must be ac-coupled. The recommended coupling capacitor is 0.1 µF.
The possible input configurations are listed in the input select register at I2C subaddress 00h (see
Section 2.11.1).
External clock reference input. It may be connected to an external oscillator with a 1.8-V compatible clock
signal or a 14.31818-MHz crystal oscillator.
Digital video output of CbCr, C[9] is MSB and C[0] is LSB. Unused outputs can be left unconnected. Also,
these terminals can be programmable general-purpose I/O.
O
For the 8-bit mode, the two LSBs are ignored.
Digital video output of Y/YCbCr, Y[9] is MSB and Y[0] is LSB.
O
For the 8-bit mode, the two LSBs are ignored. Unused outputs can be left unconnected.
Fast-switch (blanking) input. Switching signal between the synchronous component video (YPbPr/RGB)
and the composite video input.
Programmable general-purpose I/O
Genlock control output (GLCO). Two Genlock data formats are available: TI format and real time control
(RTC) format.
During reset, this terminal is an input used to program the I2C address LSB.
Power down input:
1 = Power down
0 = Normal mode
