MAX3905: MOST Automotive Transmitter Using the MAX3905 and an ULM Photonics VCSEL


Media-Oriented Systems Transport (MOST) is a growing standard for automotive multimedia networks. The low-cost, fiber-optic-based network interfaces to audio and video devices to provide integration for passenger information and entertainment networks. This discussion focuses on the MOST transmitter. The critical requirements for a MOST transmitter are the optical modulation amplitude (OMA) and average power (PAVE) at the optical output, which are specified in the MOST Advanced Optical Physical Layer Specification Draft 0.9.
