High-speed Serial I/O (transceiver) Interface
There are 8 CDR transceiver channels located on the
top side
of
HSMC ports A and E, respectively.
Each CDR transceiver can run up to 6.5Gbps.
Clock Interface
Due to the limitation of the FPGA clock input pin numbers, not all the HSMC ports have same
clock interface.
Table 2-9
shows the FPGA clock input pin placement on each HSMC port.
In addition, since FPGA dedicated clock input pins (CLK[1,3,8,10]), or corner PLL clocks don’t
support On-Chip differential termination, please solder input termination resistors on R299 and
R300, respectively, when using HSMC_CLKIN_p2/n2 and HSMA_CLKIN_p2/n2 as LVDS
signals.

I2C Interface
The I2C bus on the HSMC connectors is separated into two groups. HSMC Port A, B, and C share
the same I2C interface. HSMC ports D, E, and F share the other I2C bus.
Table 2-10
lists the
detailed distribution.
