FPGA I/O Standard Specifications for MIPI Transmitter

The DC specifications for Differential HSTL-18, 1.8 V LVCMOS, and 2.5 V LVCMOS I/O standards are as stipulated in the device datasheets for the respective devices. When an FPGA functions as a MIPI D-PHY transmitter, the transmitted high-speed and low-power signals from the FPGA I/O are expected to meet the high-speed and low-power MIPI D-PHY receiver specifications with passive resistor network.

Related Information
8 Differential HSTL-18 is a pseudo differential I/O standard consists of two single-ended HSTL-18 output buffers. One single-ended output buffer is the P channel and another single-ended output buffer is the N channel (inversion of P channel). The output differential signal (VOD) is the difference of VOH–VOL. The output common mode voltage (VOCM) is the signal crossing point for P and N channels.
