MaxLinear MXL8321 | Demoboard MxL83211 EVK

Description

The MxL83211, MxL83212, and MxL83214 (MxL8321x family) of half duplex RS-485 transceivers support up to50Mbps communication in harsh industrial environments. The bus pins tolerate high levels of IEC electrical fasttransients (EFT), IEC electrostatic discharge (ESD), and provide an extended common mode range. Seven product options with slew controlled 250kbps, 500kbps speeds, and high speed 50Mbps varieties in threedifferent packages provides a broad portfolio that can be used across different applications ranging from high speedmotor drives to wireless infrastructure and building automation. The combination of integrated EFT and ESDprotection in small MSOP and VSON packages makes these products suited for space-constrained applications thatrequire robust and high performance communication. High receiver input impedance allows 256 transceivers to share a common data bus while maintaining signal marginand without excessive loading or use of expensive repeaters. Enhanced failsafe circuitry ensures receivers provide theexpected output when the bus is shorted or left open under both terminated and unterminated conditions. Drivers includebuilt-in short-circuit protection and a thermal-overload shutdown to protect against excessive power dissipation frombus contention.
