The Tsi620 FMAC and FPGA RIO-XGMII interface function in the synchronous mode. The TX_CLK
from the Tsi620 is sourcing from its SYSCLK(p,n), while the FPGA must use RX_CLK as its
RIO-XGMII operation reference clock. The TX_CLK driven from the FPGA must therefore be
synchronized with TX_CLK driven by the Tsi620. In addition, TX_CLK of the FPGA cannot be
applied to the Tsi620 until the FPGA PLL is locked.
Figure 8: Clocking Generation and Distribution
The FPGA XGMII PLL is synchronized to received RX_CLK from the Tsi620.
The clock synthesizer
CDC6010 must be managed through its serial interface, while the DSP is responsible for CDC6010
configuration through its I2C bus.

Power Supply and Consumption Analysis
The board power distribution design must comply with AMC.1 power management requirements. The
AMC card has only 12V supply available from either AMC finger connector or DC barrel plug:
•
AMC max power consumption: <60W including all add-in cards
•
AMC finger connector: 12V@5A for MicroTCA chassis operation
•
DC barrel plug: 12V@5A for stand-alone operation
