SMSC LAN8187/LAN8187I
DATASHEET
CLKIN/XTAL1
I
Clock Input
– 25 Mhz or 50 MHz external clock or crystal input.
In MII mode, this signal is the 25 MHz reference input clock
In RMII mode, this signal is the 50 MHz reference input clock
which is typically also driven to the RMII compliant Ethernet MAC
clock input.
Note:
See
Section 4.10, "(TX_ER/TXD4)/nINT Strapping," on
page 30
for additional details on Strapping options.
XTAL2
O
Clock Output
– 25 MHz crystal output.
Note:
See
Section 4.10, "(TX_ER/TXD4)/nINT Strapping," on
page 30
for additional details on Strapping options.
Also, float this pin if using an external clock being
driven through CLKIN/XTAL1
GPO2
O
General Purpose Output 2 –
General Purpose Output signal
Driven by bits in registers 27 and 31.
GPO1
O
General Purpose Output 1 –
General Purpose Output signal
Driven by bits in registers 27 and 31. This signal is mux’d with
PHYAD4.
GPO0/MII
I/O
General Purpose Output 0 –
General Purpose Output signal.
Driven by bits in registers 27 and 31.
MII –
MII/RMII mode selection is latched on the rising edge of
the internal reset (nreset) based on the following strapping:
Float the GPO0 pin for MII mode or pull-high with an external
(see
Table 4.3, “Boot Strapping Configuration Resistors,” on
page 32
) resistor to VDDIO to set the device in RMII mode.
Note:
See
Section 4.6.3, "MII vs. RMII Configuration," on
page 26
for more details.
