4.3.1. D-PHY PHY Protocol Interface (PPI) Clock Frequencies
The MIPI D-PHY Intel FPGA IP generates high-speed word clocks on the PPI interface that are used by the CSI-2 Receiver and Transmitter to interface with the D-PHY. The frequency of these clocks are:
Equation 3. D-PHY PPI Clock Frequencies
PPI Bus Width (Bits) | Line Rate (Mbps) | rx or tx_word_clk_hs_d0 (MHz) |
---|---|---|
16 | 400 | 25 |
1500 | 93.75 | |
2500 | 156.25 |
Equation 4. Derivation of the axi4_clk
Video Data Type | Line Rate (Mbps) | PPI_Bus Width (Bits) | rx_word_clk_hs_dX (MHz) | Lanes | Pixels in Parallel | Bits per Pixel | axi4s_clk (MHz) |
---|---|---|---|---|---|---|---|
RAW10 | 800 | 16 | 50 | 2 | 1 | 10 | >160 |
RGB888 | 1500 | 16 | 93.75 | 4 | 2 | 24 | >125 |
YUV422 8-bit | 1000 | 16 | 62.5 | 8 | 4 | 8 | >250 |
