5.2.3. IP Ports

Table 22.  HDMI RX PHY Intel FPGA IP Ports
Interface Port Type Clock Domain Port Direction Description
reset Reset reset Input Main asynchronous reset
mgmt_clk Clock mgmt_clk Input Free-running system clock input (100 MHz)
rx_tmds_clk Clock rx_tmds_clk Input This clock frequency follows TMDS clock frequency. This clock is connected to the TMDS clock input from the HDMI sink connector
i2c_clk Clock i2c_clk Input Clock input for i2c (100 MHz)
systempll_clk Clock systempll_clk Input

Reference clock to RX Transceiver System PLL Clock (100 MHz). This clock is driven by F-tile Reference and System PLL clock IP output

rx_phy_cdr_refclk_frl Clock rx_phy_cdr_refclk_frl Input

Reference clock to RX Transceiver for FRL (100 MHz). This clock is driven by F-tile Reference and System PLL clock IP output

rx_phy_cdr_refclk_tmds Clock rx_phy_cdr_refclk_tmds Input

Reference clock to RX Transceiver for TMDS. This clock is driven by F-tile Reference and System PLL clock IP output. Frequency depends on TMDS Clock frequency
