• For PCS option in PMA Direct mode, this clock is half the frequency of rxlink_clk signal.

Signal to indicate the transceiver RX is ready.

Signal to indicate the transceiver RX PMA is ready. This signal must be asserted before you assert or deassert any RX resets.

Active-high hard reset signal that resets the transceiver RX interface.

Asserting this signal does not reset the transceiver PMA. Refer to the E-tile Transceiver PHY User Guide about how to reset PMA through the Avalon® memory-mapped reconfiguration interface.

L*32

Output

Indicates a 32-bit data from the DLL to the transport layer. The data format is big endian, where the earliest octet is placed in bit [31:24] and the latest octet is placed in bit [7:0].

1

Output

Indicates whether the data to the transport layer is valid or invalid. The Avalon® streaming source interface in the RX core cannot be backpressured and transmits the data when the jesd204_rx_data_valid signal is asserted.

• 0—data is invalid
• 1—data is valid

1

Input

Indicates that the Avalon® streaming sink interface in the transport layer is ready to receive data.

1

Input

Indicates an empty data stream due to invalid data. This signal is asserted high to indicate an error during data transfer from the RX core to the transport layer.

1

Input

The Avalon® memory-mapped interface clock signal. This clock is asynchronous to all the functional clocks in the JESD204B IP core. The JESD204B IP core can handle any cross clock ratio and therefore the clock frequency can range from 75 MHz to 125 MHz.

1

Input

This reset is associated with the jesd204_rx_avs_clk signal. This reset is an active low signal. You can assert this reset signal asynchronously but must deassert it synchronously to the jesd204_rx_avs_clk signal. After you deassert this signal, the CPU can configure the CSRs.

1

Input

When this signal is present, the slave port ignores all Avalon® memory-mapped signals unless this signal is asserted. This signal must be used in combination with read or write. If the Avalon® memory-mapped bus does not support chip select, you are recommended to tie this port to 1.

8

Input

For Avalon® memory-mapped slave, the interconnect translates the byte address into a word address in the address space so that each slave access is for a word of data. For example, address = 0 selects the first word of the slave and address = 1 selects the second word of the slave.

32

Input

32-bit data for write transfers. The width of this signal and the jesd204_rx_avs_readdata[31:0] signal must be the same if both signals are present.

1

Input

This signal is asserted to indicate a read transfer. This is an active high signal and requires the jesd204_rx_avs_readdata[31:0] signal to be in use.

1

Input

This signal is asserted to indicate a write transfer. This is an active high signal and requires the jesd204_rx_avs_writedata[31:0] signal to be in use.

32

Output

32-bit data driven from the Avalon® memory-mapped slave to master in response to a read transfer.

1

Output

This signal is asserted by the Avalon® memory-mapped slave to indicate that it is unable to respond to a read or write request. The JESD204B IP core ties this signal to 0 to return the data in the access cycle.

1

Input

SYSREF signal for JESD204B Subclass 1 implementation.

For Subclass 0 and Subclass 2 mode, tie-off this signal to 0.

1

Output

Indicates a SYNC~ from the receiver. This is an active low signal and is asserted 0 to indicate a synchronization request. Instead of reporting the link error through this signal, the JESD204B IP core uses the jesd204_rx_int signal to interrupt the CPU.

For multilink synchronization, you can optionally connect the DEV_SYNC_N from each IP core to the input of an AND gate. The output of the AND gate is exported to the FPGA pins for connection to the analog-to-digital converters. Refer to AN803 and AN804 for more information about the connection guidelines.
