USB 2.0 data positive pin.
USB 2.0 data negative pin.
VBUS pin input. Please connect to USB bus power.
12Mhz
±
0.003%crystal or oscillator clock input. This clock is needed for
USB PHY transceiver to operate.
12Mhz crystal or oscillator clock output.
For USB PHY’s internal biasing. Please connect to analog GND through a
resistor (12.1Kohm
±
1%).
Serial EEPROM Interface
EEPROM Clock. EECK is an output clock to EEPROM to provide timing
reference for the transfer of EECS, and EEDIO signals. EECK only drive
high / low when access EEPROM otherwise keep at tri-state and internal
pull-down.
EEPROM Chip Select. EECS is asserted high synchronously with respect to
rising edge of EECK as chip select signal. EECS only drive high / low when
access EEPROM otherwise keep at tri-state and internal pull-down.
EEPROM Data In. EEDIO is the serial output data to EEPROM’s data input
pin and is synchronous with respect to the rising edge of EECK. EEDIO
only drive high / low when access EEPROM otherwise keep at tri-state and
internal pull-up.
Ethernet PHY Interface
25Mhz
±
0.005% crystal or oscillator clock input. This clock is needed for
the embedded 10/100M Ethernet PHY to operate.
25Mhz crystal or oscillator clock output.
Receive data input positive pin for both 10BASE-T and 100BASE-TX.
Receive data input negative pin for both 10BASE-T and 100BASE-TX.
Transmit data output positive pin for both 10BASE-T and 100 BASE-TX
Transmit data output negative pin for both 10BASE-T and 100 BASE-TX
For Ethernet PHY’s internal biasing. Please connect to GND through a
12.1Kohm
±
1% resistor.
Link status LED indicator. This pin drives low continuously when the
Ethernet link is up and drives low and high in turn (blinking) when Ethernet
PHY is in receiving or transmitting state.
