3.3
For the ZL50111 variant the packet interface is capable of either 3 MII interfaces, 2 GMII interfaces or 2 TBI
(1000 Mbps) interfaces. The TBI interface is a PCS interface supported by an integrated 1000BASE-X PCS
module. The ZL50110 variant has either 2 MII interfaces, 2 GMII interfaces or 2 TBI (1000 Mbps) interfaces. Ports 2
and 3 are not available on the ZL50110 device.
NOTE: In GMII/TBI mode only 1 GMAC port may be used to receive data. The second GMAC port is for
redundancy purposes only.
Data for all three types of packet switching is based on Specification IEEE Std. 802.3 - 2000. For the ZL50111
variant, only Ports 0 and 1 have the 1000 Mbps capability necessary for the GMII/TBI interface. In either GMII or
TBI mode Ports 2 and 3 are disabled. Alternatively 3 ports can be used as 100 Mbps MII interfaces, either Ports 0,
1 and 2 or Ports 0, 1 and 3.
Note: Port 2 and Port 3 can not be used to receive data simultaneously, they are mutually exclusive for packet
reception. They may both be used for packet transmission if required.
Table 7 maps the signal pins used in the MII interface to those used in the GMII and TBI interface. Table 8 shows all
the pins and their related package ball, but is based on the GMII/MII configuration.
All Packet Interface signals are 5V tolerant, and all outputs are high impedance while System Reset is LOW.
Note: Mn can be either M0, M1, M2, or M3 for ZL50111 variant; and M0 or M1 for ZL50110 variant.
