6.1. GTS SDI II IP Core Resets and Clocks

Table 14.  Resets and Clock Signals
Signal Width Direction Description
tx_rst 1 Input

Reset signal for the transmitter. This signal is active high and level sensitive.

This signal must be synchronous to tx_pclk clock domain.

rx_rst 1 Input

Reset signal for the receiver. This signal is active high and level sensitive. This reset signal must be synchronous to the rx_coreclk or rx_coreclk_hd clock domain.

rst_trig_rst 1 Output Reset output signal to the transceiver reset controller to reset the transceiver. This signal is synchronous to the rx_coreclk or rx_coreclk_hd clock domain.
tx_axi4s_reset 6 1 Input Tx AXI4-Stream reset.
rx_axi4s_reset 6 1 Input Rx AXI4-Stream reset.
tx_pclk 1 Input

Transmitter core parallel clock signal. This clock signal must be driven by the by parallel output clock from TX transceiver.

  • SD-SDI = 148.5 MHz
  • HD-SDI = 74.25 MHz or 74.175 MHz, depending on video frame rate
  • 3G-SDI = 148.5 MHz or 148.35 MHz, depending on video frame rate
  • HD-SDI Dual Link = 74.25 MHz or 74.175 MHz, depending on video frame rate
  • Dual Rate = 148.5 MHz or 148.35 MHz, depending on video frame rate
  • Triple Rate = 148.5 MHz or 148.35 MHz, depending on video frame rate
  • Multi Rate (up to 12G-SDI) = 148.5 MHz or 148.35 MHz, depending on video frame rate
rx_coreclk 1 Input
Receiver core clock signal. You can set the following frequencies:
  • 148.5-MHz or 148.35-MHz: Applicable for all configurations.
Note: For the Agilex™ 5 device, set the clock frequency range between 100 MHz to 156.25 MHz. Intel recommends sharing the same clock as the i_csr_clk port from the F-Tile Dynamic Reconfiguration Suite IP core.

This clock source must be stable and there are no required relationships with any other clocks. The clock source can be asynchronous or synchronous to any transceiver's clock.

Note: Not applicable if the selected transceiver reference clock frequency is 74.25 MHz/74.175 MHz.
xcvr_rxclk 1 Input

Receiver parallel clock input. Driven by rx_pma_div_clkout (for multi-rate modes) or rx_clkout (for other modes) from the transceiver.

  • SD-SDI = 148.5 MHz
  • HD-SDI = 74.25 MHz or 74.175 MHz, depending on video frame rate
  • 3G-SDI = 148.5 MHz or 148.35 MHz, depending on video frame rate
  • 6G-SDI = 148.5 MHz or 148.35 MHz, depending on video frame rate
  • 12G-SDI = 148.5 MHz or 148.35 MHz, depending on video frame rate
tx_axi4s_clk 6 1 Input TX AXI4-Stream clock.
rx_axi4s_clk 6 1 Input RX AXI4-Stream clock.
