The MXL-LVDS-DPHY-DSI-TX is a combo PHY that consists of a high-frequency low-power, low-cost, source-synchronous, Physical Layer supporting the MIPI Alliance Standard for D-PHY and a high performance 4-channel LVDS Serializer implemented using digital CMOS technology.

In LVDS mode, both the serial and parallel data are organized into 4 channels. The parallel data is 7 bits wide per channel. The input clock is 25MHz to 150MHz. The serializer is highly integrated and requires no external components. The circuit is designed in a modular fashion and desensitized to process variations. This facilitates process migration, and results in a robust design.
