Functional Description
2.1
SerDes1 and SerDes2 of the MSC8156 family high speed serial interface (HSSI) are independent,
configurable, multiprotocol four-lane serial ports. SerDes1 supports Serial RapidIO and SGMII ports;
SerDes2 supports Serial RapidIO, SGMII, and PCI Express ports in different modes. The ADS supports
all available MSC8156 family SerDes configurations. Refer to the Device Specific Reference Manual for
details on multiplexing configuration.
The ADS links the MSC8156 family SerDes ports to the AMC ports. When the SerDes port is configured
in SGMII mode, the differential signals go to the SGMII switch over the Pericom PI2DBS212ZHE 1:2
differential channel multiplexer/demultiplexer switch as shown on the Figure 2-1.
The multiplexer is capable of data rates up to 1.8 GHz or 3.6 Gbps and is able to multiplex two
differential pairs in two directions. DIP-switches SW5.2,3 SEL1 and SEL2 dispatch SerDes lanes. All
SerDes lines have DC blocking capacitors 0.1 µF. Differential pairs are routed with 100 Ω impedance.
Freescale Semiconductor
Note: Some configuration modes do not use all lanes. SGMII switch ports are configured for working lanes only.
