Table 1. Clocking, Reset, Interrupt, EOL, and EOF Ports
Name Direction Width Description
s_axi_lite_aclk I 1 Clock associated with the S_AXI_LITE interface.

Frequency Range: 250 to 300 MHz

s_axi_lite_rstn I 1 Reset associated with the S_AXI_LITE interface.
eol_path<0/1> O 1 Drives the end of line (EOL) on the VCU2 IP, when low latency path<0/1> is enabled.
eof_path<0/1> O 1 Drives the end of frame (EOF) on the VCU2 IP, when low latency path<0/1> is enabled.
t<0/1/2>_pl_isp_vidin<0/1/2/3/4>_clk I 1 Clock associated with the TILE<0/1/2>_ISP_MIPI_VIDIN<0/1/2/3/4> interface.

Maximum Frequency: 400 MHz

tile<0/1/2>_isp_mipi_vidin<0/1/2/3/4>_header_data I 32 Header data (sideband signal) associated with the TILE<0/1/2>_ISP_MIPI_VIDIN<0/1/2/3/4> interface.
tile<0/1/2>_isp_mipi_vidin<0/1/2/3/4>_header_valid I 1 Header valid (sideband signal) associated with the TILE<0/1/2>_ISP_MIPI_VIDIN<0/1/2/3/4> interface.
tile<0/1/2>_isp_pl_vidout<0/1>_clk O 1 Clock from ISP<0/1> to the PL for TILE<0/1/2> (PO and SO of ISP<0/1> instance). The PL uses this to loop back for video streaming interface clocking for TEILE<0/1/2>.

Maximum Frequency: 400 MHz

tile<0/1/2>_pl_isp_vidout<0/1>_clk I 1 Clock for the Processed Video output stream to the PL for tile<0/1/2> (PO and SO of ISP<0/1> instance). If loop back is used, you can connect TILE<0/1/2>_isp_pl_vidout<0/1>_clk.

Maximum Frequency: 400 MHz

tile<0/1/2>_nmu<0/1>_axi_clk O 1 Clock associated with the TILE<0/1/2>_ISP0_NMU interface.

Maximum Frequency: 1080 MHz

tile<0/1/2>_nsu_axi_clk O 1 Clock associated with the TILE<0/1/2>_ISP_NSU interface.

Maximum Frequency: 360 MHz

tile<0/1/2>_isp<0/1>_fusa_irq O 1 ISP<0/1> core instance FUSA interrupt of TILE<0/1/2>. Must connect to LPD interrupts on the Processing System Wizard because it must be severed by the RPU.
tile<0/1/2>_isp<0/1>_isp_irq O 1 ISP<0/1> core instance interrupt of TILE<0/1/2>. Must connect to LPD interrupts on the PS Wizard because it must be severed by the RPU.
tile<0/1/2>_isp_isr_irq O 1 TILE<0/1/2> ISP ISR interrupt. Must connect to LPD interrupts on the PS Wizard because it must be severed by the RPU.
tile<0/1/2>_isp_xmpu_interrupt O 1 TILE<0/1/2> XMPU interrupt. Must connect to LPD interrupts on the PS Wizard because it must be severed by the RPU.
tile<0/1/2>_ref_dpll_clk I 1 TILE<0/1/2> reference input clock. Must be driven from the PS Wizard PL clock output.

Frequency Range: As supported by the PL clock from the PS Wizard.

tile<0/1/2>_pl_isp_rstn I 1 Resets the DPLL and soft logic modules in the PL fabric.
mipi_8ppc_vidin_header_data I 32 Header data (sideband signal) associated with the MIPI_8PPC_VIDIN interface.
mipi_8ppc_vidin_header_valid I 1 Header valid (sideband signal) associated with the MIPI_8PPC_VIDIN interface.
pl_isp_mipi300M_clk I 1 Clock associated with the MIPI_8PPC_VIDIN interface. You must supply 300 MHz to this port.
  1. <0/1/2> can be 0, 1, or 2.
  2. <0/1> can be 0 or 1.
  3. <0/1/2/3/4> can be 0, 1, 2, 3, or 4.
