3.1. Clocks

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.

Table 10.   F-Tile JESD204C IP Clocks
Clock Signal Formula Description

TX/RX device clock

j204c_pll_refclk

PLL selection The device clock is the PLL reference clock to the transceiver PLL.

TX/RX link clock

j204c_txlink_clk

j204c_rxlink_clk

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

j204c_txframe_clk

j204c_rxframe_clk

(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

j204c_tx_avs_clk

j204c_rx_avs_clk

— 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

j204c_phy_clk

Line rate/64

The PHY clock internally generated from the transceiver parallel clock for the TX path.
Transceiver reconfiguration clock

reconfig_xcvr_clk

— The transceiver reconfiguration clock. The frequency range of this clock is 100 MHz.
System PLL clock

sysclk

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.
