Clocking - 2.0 English

The list of clocks in UHD-SDI Audio (Embed).

s_axi_aclk

This is the processor domain clock. AXI4-Lite interface works on this clock.

s_axis_clk

This is the AXI4-Stream interface clock. This should be greater than 512 times the audio sampling rate.

sdi_embed_clk

This is the video domain clock. It is 74.25 MHz or 74.175 MHz during HD SDI, 148.5 MHz or 148.35 MHz during SD/3G/6G SDI and 297 MHz during 12G SDI mode. This is the same clock connected to sdi_tx_clk of the AMD UHD-SDI TX Subsystem.

s_axi_aclk

This is the processor domain clock. AXI4-Lite interface works on this clock.

m_axis_clk

This is the AXI4-Stream interface clock. This should be greater than 512 times the audio sampling rate.

sdi_extract_clk

This is the video domain clock. It is 74.25 MHz or 74.175 MHz during HD SDI, 148.5 MHz or 148.35 MHz during SD/3G/6G SDI and 297 MHz during 12G SDI mode. This is the same clock connected to sdi_rx_clk of the AMD UHD-SDI RX Subsystem.
