2.4.1.1. DQS Trees
The PHY Lite for Parallel Interfaces Intel® FPGA IP supports two DQS trees, namely an x8 tree that span over one lane and an x16 tree that spans over two adjacent lanes, as described in the following table:
DQS Tree | Lane Used | Group Size | Strobe Pins |
---|---|---|---|
X8 | Any lane | 1-10 | Pins 4, 5 |
X16 | [0,1] [2,3] [4,5] [6,7] |
1-22 | Pins 4, 5 of the even lane |
For single-ended strobe, only pin 4 is used as DQS. The remaining strobe pin (pin 5) cannot be used as data.
