CM6X reference design: RS485 design based on NXP I.MX6 CM6X core module.
The CM6X is a core module based on the NXP’s I.MX6 Cortex-A9 processor. The core module is Measured only 67.6mm by 46mm, integrates 2GBytes DDR3 SDRAM and up to 8GBytes eMMC flash.
The ISO1176 is an isolated differential line transceiver designed for use in PROFIBUS applications. The device is ideal for long transmission lines since the ground loop is broken to provide for operation with a much larger common mode voltage range. The symmetrical isolation barrier of each device is tested to provide 2500 Vrms of isolation between the line transceiver and the logic level interface.
