Description
28
SMRXDV3
lPU/O
Switch MII receive data valid
Strap option:
MII mode selection
PU = PHY mode.
PD = MAC mode (In MAC mode, port 3 MII has to connect a powered active
external PHY for the normal operation)
29
SMRXD33/
REFCLKO_3
lPU/O
MLLJ: Switch MII receive data bit 3/
Strap option:
enable auto-negotiation on port 2 (P2ANEN)
PU = enable P2ANEN
PD = disable P2ANEN
30
SMRXD32
IPU/O
Switch MII receive data bit 2
Strap option:
Force the speed on port 2
PU = force port 2 to 100BT if P2ANEN = 0
PD = force port 2 to 10BT if P2ANEN = 0
31
SMRXD31
IPU/O
Switch MII receive data bit 1
Strap option:
Force duplex mode (P2DPX)
PU = port 2 default to full duplex mode if P2ANEN = 1 and auto-negotiation
fails. Force port 2 in full duplex mode if P2ANEN = 0.
PD = Port 2 set to half duplex mode if P2ANEN = 1 and auto-negotiation
fails. Force port 2 in half duplex mode if P2ANEN = 0.
32
GND
Digital ground
33
SMRXD30
lPU/O
Switch MII receive data bit 0
Strap option:
Force flow control on port 2 (P2FFC)
PU = always enable (force) port 2 flow control feature, regardless of Auto-
Negotiation result.
PD = port 2 flow control is enabled by auto- negotiation result.
34
SCRS3/
NC
I/O
MLLJ: Switch MII carrier sense
Internal pull up.
35
SCOL3/
NC
I/O
MLLJ: Switch MII collision detect
Internal pull up.
36
SMRXC3/
NC
I/O
MLLJ: Switch MII receive clock.
Output in PHY MII mode
Input in MAC MII mode
.
37
GND
Digital ground
38
VDDC
P
1.8V digital core power input from VDDCO (pin 56).
39
SPIQ
lPU/O
SPI slave mode: serial data output
Note: an external pull-up is needed on this pin when it is in use.
Strap option:
XCLK Frequency Selection
PU = 25 MHz
PD = 50 MHz
40
SPISN
I
SPI slave mode: chip select (active low)
When SPISN is high, the KSZ8873MLLJ is deselected and SPIQ is held in
high impedance state.
A high-to-low transition is used to initiate SPI data transfer.
Note: an external pull-up is needed on this pin when it is in use.
