1 csr_bit_reversal Bit reversal for LSB/MSB first serialization. This is a compile-time option which needs to be set before IP generation.
  • 0 = LSB-first serialization
  • 1 = MSB-first serialization
Note: JESD204B converter device may support either MSB-first serialization or LSB-first serialization.

You must set both csr_byte_reversal and csr_bit_reversal bits to 1 when generating the IP.

When csr_bit_reversal = 1, the word aligner reverses the RX parallel data bits upon receiving the PMA deserialized data.

For example; in 20-bit mode; D[19:0] is rewired to D[0:19] and in 40-bit mode; D[39:0] is rewired to D[0:39].

  • 1 = Disable lane alignment detection

  • 1 = Enable lane synchronization (Default).

    The IP expects the DLL state from the transmit device to transition from CGS to ILAS then to USER DATA and checks from ILAS.

24:21 csr_syncn_delay

This 4-bit register extends SYNC_N assertion (low state) by delaying the deassertion. The legal value is 0 to 15; with 0 indicating no additional delay on SYNC_N deassertion.

For Subclass 0, the value indicates the number of link clocks SYNC_N will be extended.

For Subclass 1 and 2, the value indicates the number of multiframes SYNC_N will be extended.

RW 0x00
20 csr_cgs_bypass_sysref

This bit applies to Subclass 1 only. Enabling DLL states transition from Code Group Synchronization (CGS) to Initial Lane Alignment Sequence (ILAS) to bypass SYSREF single detect sampling.

By default, the JESD204B IP remains in CGS state (asserting SYNC_N) until SYSREF is sampled. Once csr_sysref_singledet is cleared, then only the DLL state can transition from CGS to ILAS on the next LMFC tick.

Write 1 to this register to allow the IP to exit out of CGS state without ensuring that at least one rising edge of SYSREF was sampled.

Note: This is a debug mode, where you can bypass SYSREF sampling if only a quick link up is required. Setting this bit to 1 may cause race condition between SYSREF sampling and CGS exit.
RW 0x0
19:12 csr_lmfc_offset

The LMFC offset is binary value minus 1. Upon the detection of the rising edge of SYSREF in continuous mode or single detect mode, the LMFC counter resets to the value set in csr_lmfc_offset.

LMFC counter operates in link clock domain, therefore the legal value for the counter is from 0 to ((FxK/4)-1). If an out-of-range value is set, the LMFC offset internally resets to 0.

By default, the rising edge of SYSREF will reset the LMFC counter to 0. However, if the system design has large phase offset between the SYSREF sampled by the converter device and the FPGA, you can virtually shift the SYSREF edges by changing the LMFC offset reset value using this register.

RW 0x00
11 csr_force_rbd_release

Setting this bit will force RBD elastic buffer to be released immediately when the latest arrival lane arrived in the system.

It indirectly forces csr_rbd_offset to rx_status0 (0x80) csr_rbd_count. This register overrides csr_rbd_offset.

RW 0x0
10:3 csr_rbd_offset

This is a binary minus 1 value. RX elastic buffer will align the data from multiple lanes of the link and release the buffer at the LMFC boundary (csr_rbd_offset = 0).

This register provides flexibility for an early RBD release opportunity. Legal value of RBD offset is from ((FxK/4)-1) down to 0 as it is aligned in number of link clocks. If csr_rbd_offset is set out of the legal value, the RBD elastic buffer will be immediately released.

Note: In Subclass 1, the earliest lane data right up to the latest lane data will be stored in the elastic buffer. The data is deskewed and release at the LMFC boundary where (csr_rbd_offset = 0). The position of the latest lane arrival with respect to the LMFC internal counter will be reported in register rx_status0 (0x80) csr_rbd_count. Set a safe RBD release in this register to ensure deterministic latency in power cycle mode. Refer to the application note on deterministic latency for more information.
RW 0x0
2 csr_sysref_singledet

This register enables LMFC realignment with a single sample of rising edge of SYSREF. The bit is auto-cleared by hardware once SYSREF is sampled. If you require SYSREF to be sampled again (due to link reset or reinitialization), you must set this bit again.

This register also has another critical function. The JESD204B IP never exits out of CGS unless at least a SYSREF edge is sampled. This is to prevent race condition between SYSREF being sampled and the exit of CGS to ILAS. If CGS transitions to ILAS before the common SYSREF is sampled for both the IP and converter device, this would cause undeterministic latency as the ILAS is transmitted based on the free running LMFC counter coming out of reset.

  • 0 = Any rising edge of SYSREF will not reset the LMFC counter.
  • 1 = Resets the LMFC counter on the first rising edge of SYSREF and then clears this bit. (Default)

Intel recommends to use csr_sysref_singledet with csr_sysref_alwayson even if you want to do SYSREF continuous detection mode. This is because this register is able to indicate whether SYSREF was ever sampled. This register also prevents race condition as mentioned above. Using only SYSREF single detect mode will not be able to detect incorrect SYSREF period.

RW 0x1
1 csr_sysref_alwayson

This register enables LMFC realignment at every rising edge of SYSREF. LMFC counter is reset when every SYSREF transition from 0 to 1 is detected.

0 = Any rising edge of SYSREF will not reset the LMFC counter.

1 = Continuously resets LMFC counter at every SYSREF rising edge.

When this bit is set, the SYSREF period will be checked to make sure it never violates internal extended multiblock period and this period can only be n-integer multiplied of ((FxK)/4).

If the SYSREF period is different from the local extended multiblock period, register rx_err (0x60) csr_sysref_lmfc_err will be asserted and an interrupt will be triggered.

If you want to change SYSREF period, this bit should be set to 0 first. After SYSREF clock has stabilized, this bit is set to 1 to sample the rising edges of the new SYSREF.

RW 0x0
0 csr_link_reinit

The JESD204B IP will reinitialize the link to enter Code Group Synchronization by driving SYNC_N signal to 0. The software must check that SYNC_N (register rx_status0 (0x80) csr_dev_syncn) is 1 before setting this register. (This bit will be automatically cleared once link reinitialization is entered by hardware).

  • 0 = No link reinit request (Default)
  • 1 = Reinitialize the link.

Note: If this error detection is not required, you can tie off the jesd204_rx_data_readysignal from the upstream to 1, in the Intel FPGA transport layer. This is the error from the transport layer instead from the JESD204B RX core.

10:3 csr_rbd_count

This is a binary minus 1 value. Legal value reported from this register is ((FxK/4)-1) to 0.

  • When csr_rbd_count = 0, this indicates that the latest lane arrives within the link at the LMFC boundary.
  • When csr_rbd_count = 1, this indicates that the latest lane arrives within the link at 1 link clock cycle before the LMFC boundary.
Note: When the latest lane arrival in the link is too close to the LMFC boundary, Intel recommends to set the RBD release opportunity (sysref_ctrl 0x54 rbd_offset) at least 2 link clocks away from the csr_rbd_count register to accommodate for worst-case power cycle variation.
