Local Clock : Must be run at 25Mhz . Used for transmit data to PHY devices,
Reset : The chip is reset when this signal is asserted Low.
Repeater Identification Number Daisy-Chain In : When MODE=” 1” , This
pin is a daisy chain serial input for Repeater ID. A state machine always
monitor the input if a correct data (RID) present at the pin, the (RID+1) will
be written to RID register and override the power on setup RID for the chip.
/LSEL10 : When MODE=” 0” , This pin select 10Mbps global LED status
(
LED status is selected.
Repeater Identification Number Daisy-Chain Out : When MODE=” 1” , This
pin is periodically shift out the RID of itself to the next chained chip to
inform that this ID has already been occupied. The RID is shift out
periodically every about 200us.
/LCOL : When MODE=” 0” , This pin drives 10Mbps collision LED directly.
MII Clock Out : 2.5MHz 10Mbps MII reference clock
Station Management Data Out : For setup PHY auto-negotiation registers.
A burst write commands are issue to setup PHY register after reset. The PHY
address 4h, 5h, 6h, 7h, 8h, 9h,Ah and Bh will be written as register 4h to
value 00A1h ( Advertise register set to 10/100 half-duplex mode)and register
0h to value 1000h(Enable auto-negotiation).
Station Management Data Clock Out : For MDO reference clock.
Test Pin : The pin is just for test mode setting purpose only. Must be pull low
when normal operation.
Half-duplex mode in 10Mbps : Pull low with 10K ohm resister for 10Mbps
PHY in half-duplex mode.
POWER : +5V +/-5%
POWER: 0V
