Xtal out. 25 MHz reference clock output. When an external 25 MHz crystal is
used, this pin is connected to one of its terminals. If an external clock source is
used, then this pin should be left open.
Differential transmit outputs (100Base-TX, 10Base-T). These pins output
directly to the transformer. When MDIX is enabled, they can work as RXP/RXN
Signal detect (ST802RT1B version only) see
Connect a 100 Ω resistor between TXn and VCCA and between TXp and
VCCA to achieve the pseudo-emitter coupled logic (PECL) levels for the optical
transmitter. The PECL logical low level (PECL

resistor
Differential receive inputs (100Base-TX, 10Base-T). These pins directly
output to the transformer. When MDIX is enabled they can work as TXP/TXN
Reference resistor/DC regulator output. Reference resistor connecting pin
for reference current, directly connect a 5.25 kΩ ± 1% resistor to V
Link LED. In Mode 1 and Mode 2 this pin indicates the status of the link. The
LED is ON when the link is good.
Speed LED. This pin is driven on continually when 10Mb/s or 100Mb/s network
operating speed is detected.(All modes -> ON: 100Mb/s, OFF: 10Mb/s)
Activity/collision LED. This pin is driven on continually when a full-duplex
configuration is detected. This pin is driven on at a 20 Hz blinking frequency
when a collision status is detected in the half-duplex configuration. (Mode 2 ->
BLINK: activity - Mode 1 -> ON: full-duplex, BLINK: collision)
Reset (active-low). This input must be held low for a minimum of 1 ms to reset
the ST802RT1x. During power-up, the ST802RT1x is reset regardless of the
state of this pin. Reset is not complete before 1 ms plus an MDC transition.
Power-down. This pin is an active low input in this mode and should be
asserted low to put the device in a power-down mode. During power-down
mode, TXP/TXN outputs and all LED outputs are 3-stated, and the MII interface
is isolated. The power-down functionality is achievable by software by asserting
bit 11 of register RN00.
(No connection) - Should be pulled low for normal operation through an external
resistor of 2.2 kΩ
