The F-Tile JESD204C IP runs on link clock (link layer) and frame clock (transport layer). The transceiver runs in the link clock domain and the serial clock domain.
TX/RX device clock
|PLL selection||The device clock is the PLL reference clock to the transceiver PLL.|
TX/RX link clock
|Line rate/66||The timing reference for the F-Tile JESD204C IP. The link clock is line rate divided by 66 because the link clock operates in a 66-bit data bus domain architecture after 64B/66B encoding.|
TX/RX frame clock
|(Link clock frequency*FCLK_MULP) MHz||The frame clock as per the JESD204C specification. The frame clock is always 1x or 2x of the link clock.|
TX/RX Avalon® memory-mapped clock
|—||The configuration clock for the F-Tile JESD204C IP control and status registers through the Avalon® memory-mapped interface. This clock is asynchronous to all the other clocks. The frequency range of this clock is 75 to 125 MHz.|
TX PHY clock
The PHY clock internally generated from the transceiver parallel clock for the TX path.
|Transceiver reconfiguration clock
|—||The transceiver reconfiguration clock. The frequency range of this clock is 100 MHz.|
|System PLL clock
|System PLL clock frequency >= Native clock frequency||The F-Tile system PLL clock frequency is user-defined. The system PLL clock frequency is greater or equal to the native clock frequency.|
