Multiprotocol

MaxLinear offers the industry’s largest portfolio of multiprotocol transceivers. Our dual protocol transceivers allow RS-232 or RS-485 communication in a single IC. Our multiprotocol transceivers support up to 12 serial protocols: RS-232, RS-485, RS-422, RS-449, EIA-530, EIA-530A, V.10, V.11, V.28, V.35, V.36 and X.21.
Advanced features, like built-in cable termination, adjustable logic level, diagnostic loopback modes and 15kV ESD protection, provide maximum versatility and robust serial communication and greatly simplify the use of multiple serial protocol standards over a single connector. These products enable our customers to reduce their component and connector count, lower their Bill of Materials (BOM) costs and customize their end products on the fly or in the field.
