8.4.1.2 Input Data Interface (DIN) Training

The DLPC410 detects the phase differences between the ½ speed clock (used in the customer device driving the LVDS data) and the internally generated ½ speed data clocks and automatically corrects their alignment. This is done by the customer FPGA supplying a simple repeating pattern on all of the data inputs while the INIT_ACTIVE output of the DLPC410 is high/active. The details of the training pattern are described below.

This is a simple block diagram of the training pattern insertion logic.

DLPC410 blk_dia_logic_lps024.gifFigure 11. Block Diagram of Training Pattern Logic

The expected training pattern is 0100. In Figure 12 the data input to the 4:1 SERDES cells is captured on the rising edge of the ½ speed system clock. The output latency shown is based on the documentation for the Xilinx SERDES cells. Individual implementation may vary depending on the type of cells, technology, and design technique used.

DLPC410 patt_align_lps024.gifFigure 12. Training Pattern Alignment

NOTE

In Xilinx FPGAs (due to the construction of the ISERDES and OSERDES cells) a pattern of 0010 needs to be applied to the output/transmitting SERDES cells data pins (D1 = 0, D2 = 0, D3 = 1, D4 = 0) in order to receive a result of 0100 (Q1 = 0, Q2 = 1, Q3 = 0, Q4 = 0) at the input/receiving SERDES cell.

The patterns should be applied on all of the input data and DVALID pins. In this respect, the interface is treated as a 17 bit interface with DVALID being the 17th data bit. The receiving logic in the DLPC410 will shift the data until the correct pattern is seen at the inputs. The SERDES cells align the incoming data with the ½ speed system clock (derived from the full speed data clock). This allows DLPC410 to correctly align the DVALID signal and the incoming data and will contribute to a more robust interface. It is important that the training pattern is applied to the DVALID and data inputs of the DLPC410 before reset to the device is deasserted, as training commences immediately on the deassertion of reset. The INIT_ACTIVE signal is asserted while the device is held in reset in order to help facilitate this behavior.
