Clock select 0. If this terminal is set to low (0) then the speed is 98.304 Mbps. If this terminal is set to
high (1) the speed is 49.152 Mbps.
To operate at 100 Mbps requires an input clock of 98.304 MHz. To operate at 49.152 Mbps requires
an input clock of 49.152 MHz.
Clock select 1. CLK_SEL1 must be tied to ground during normal operation.

I/O
Control I/O. These are bidirectional signals that communicate between the TSB14AA1A and the
link layer that controls the passage of information between the two devices.
Data I/O. These are bidirectional information signals that communicate the data between the
TSB14AA1A and the link layer controller.
Enable on-chip regulator. This active low pin enables the 1.8 V on

External ID 0. The state of this pin sets the value of bit 0 of the
PHYSICAL_ID
field in the
NODE ID
Register upon hardware or SWHRST reset. The register bit may be modified by software.
External ID 1. The state of this pin sets the value of bit 1 of the
PHYSICAL_ID
field in the
NODE ID
register upon hardware or SWHRST reset. The register bit may be modified by software.
External ID 2. The state of this pin sets the value of bit 2 of the
PHYSICAL_ID
field in the
NODE ID
register upon hardware or SWHRST reset. The register bit may be modified by software.
External ID 3. The state of this pin sets the value of bit 3 of the
PHYSICAL_ID
field in the
NODE ID
register upon hardware or SWHRST reset. The register bit may be modified by software.
External ID 4. The state of this pin sets the value of bit 4 of the
PHYSICAL_ID
field in the
NODE ID
register upon hardware or SWHRST reset. The register bit may be modified by software.
External ID 5. The state of this pin sets the value of bit 5 of the
PHYSICAL_ID
field in the
NODE ID
register upon hardware or SWHRST reset. The register bit may be modified by software.
External priority 0. The state of this pin sets the value of bit 0 of the
PRIORITY
field in the
PRIORITY
register upon hardware or SWHRST reset. The register bit may be modified by software.
External priority 1. The state of this pin sets the value of bit 1 of the
PRIORITY
field in the
PRIORITY
register upon hardware or SWHRST reset. The register bit may be modified by software.
External priority 2. The state of this pin sets the value of bit 2 of the
PRIORITY
field in the
PRIORITY
register upon hardware or SWHRST reset. The register bit may be modified by software.
External priority 3. The state of this pin sets the value of bit 3 of the
PRIORITY
field in the
PRIORITY
register upon hardware or SWHRST reset. The register bit may be modified by software.

Invert data strobe. When this pin is set low, the TDATA, TSTRB, RDATA, RSTRB, OCDOE, and
TDOE pins operate normally (i.e., true). When this pin is set high, these six pins are inverted.
Link-On output. This pin notifies the LLC to power-up and become active. LINKON is a square-wave
signal with a frequency between 4 and 8 MHz when active. LINKON is otherwise driven low, except
during a hardware reset when it is high impedance.
LINKON is activated if the LPS is inactive (LLC inactive) and when the PHY receives a link-on PHY
packet addressed to this node.
Once activated, LINKON will continue active until the LPS becomes active (LLC active). The PHY
also deasserts (low) LINKON when a bus-reset occurs.
