3.8.5. MIPI CSI-2 Transmitter

The MAX® 10 FPGA 10M50 Evaluation Kit supports one MIPI CSI-2 transmitter D-PHY to Leopard LI-MIPI-USB3-Tester module. This module includes one MIPI clock channel and four MIPI data channels. To interface the CSI-2 D-PHY compliant I/Os, the MAX® 10 FPGA 10M50 Evaluation Kit uses one 1.8 V HSTL signal pair and one 2.5 V LVCMOS signal pair to support both high-speed and low-power nodes of one MIPI clock or data lane. The control signals (RST, SCLK, and SDATA) for LI-MIPI-USB3-Tester are implemented with both 1.8V and 3.3V options.

CAUTION:
The implemented D-PHY resistor values need to be adjusted based on user design. Simulation and signal quality measurement is required for optimal resistor values. Refer to AN-754: MIPI D-PHY Solution with Passive Resistor Networks in Altera® Low-Cost FPGAs for technical details on implementing the D-PHY passive circuits. You must also install control signal path resistors (SCLK, SDATA, RST_IO) depending upon the I/O level desired.
