Description |
|---|---|---|---|
|
aclk |
Input |
1 |
AXI4-Stream ACLK. |
|
aclken |
Input |
1 |
AXI4-Stream ACLKEN. Active-High. |
|
aresetn |
Input |
1 |
AXI4-Stream ARESETN. Active-Low. Synchronous to ACLK. |
|
axis_enable |
Input |
1 |
This input should be connected to the VTC detector locked status and is synchronous to vid_io_in_clk. 1 = Enable writes into FIFO 0 = Disable writes into FIFO |
|
fid |
Output |
1 |
Field-ID for AXI4-Stream bus. Used only for interlaced video: 0=even field, 1=odd field. This bit changes coincident with SOF on the AXI4-Stream bus. It should be connected to the field-ID bit of the next device downstream that is field-aware, otherwise it should be left unconnected. Synchronous to aclk. |
|
vid_io_in_clk |
Input |
1 |
Native video clock. Only available in independent clock mode. |
|
vid_io_in_ce |
Input |
1 |
Native video clock enable |
|
vid_io_in_reset |
Input |
1 |
Native video clock domain reset. Synchronous to vid_io_in_clk. Only available in independent clock mode. Active-High. |
|
overflow |
Output |
1 |
Flag indicating that the FIFO has over-flowed. Synchronous to vid_io_in_clk. If an overflow occurs, this could indicate that the connected AXI4-Stream Slave is creating excessive back-pressure. |
|
underflow |
Output |
1 |
Flag indicating that the FIFO has under-flowed. This should never occur under normal operation. Synchronous to aclk. |
