[SOLVED] AVR 3.3V Rs422 Interface to 1.8v LVDS Camera driver

[abdul991]

Hello Guys... I've gone through the post relating to RS422 to FPGA and others.. But i am still bit confused.. I'm using a Rs422 communication with AVR microcontroller.. I need to interface my microcontroller to a camera link driver board which works on 1.8V LVDS, i require both direction communication AVR 3.3V to the driver board(LVDS) and vice versa..

Can any one suggest me a converter IC which is compatible, or do i need to convert my both end signals to TTL level each time in between to establish communication. Do you still need additional information to reply please let me know....

If the camera driver board actually does UART communication with LVDS level (not sure about that), you can use a 3.3V LVDS driver/receiver IC like SN65LVDS179.

No the camera driver only supports the LVDS 1.8V with max 350mV difference voltage... anyways thanks for support ... As the problem got rectified by voltage divider circuit.. This worked for me
