Fiber Optic Transceiver Complies with 150 Mbps MOST Physical Layer
Melexis has developed the MLX75605, a single package solution for a 150 Mbps fiber optic transceiver dedicated to the newly introduced MOST150 physical layer. It comes in a 24 pin SOIC package compatible with lead free SMD processes. The transceiver includes integrated ferrule receptacles for both receiver and transmitter pigtails with high optical coupling efficiency. Light output is eye safe. MLX75605 embeds a 650 nm light source, a 150 Mbps driver IC and a 150 Mbps monolithic receiver IC. The solid state lighting device (SSLD) includes on-chip calibration circuitry, which allows trimming the transmitter light output. In this way the light output is within a narrow range over the entire temperature range -40°C to +95°C, as required for automotive infotainment networks. The 150 Mbps receiver part consists of a PIN Photo Diode, TIA and end amplifiers integrated into one single die. This monolithic receiver IC enables immunity against electromagnetic disturbances. The MLX75605 is packaged using package technology developed for automotive Optoelectronic ICs. The monolithic Receiver IC (MLX75603) as well as the SSLD IC (MLX75604) are also available in die form. The MLX75605 is value priced at $5.69 at 100k quantities.
