i have a 'art project' (costume) where i have some LED-Drivers (TLC5957) about 2meters away from my controller.
The Drivers have multiple Signals (GrayscaleClock, SignalClock, SignalData, Latch) that can go up to 30MHz.
So my Idea was to use RS485 / RS422 or LVDS to transmit this over the 2meter.
My Power Supply and IO Voltage is all 3.3V.
Can you Recommend any Drivers for this type of Application?
do i have advantages choosing one over the other technology?
for RS422 i have found this Pair:
- AM26LV31E Low-Voltage High-Speed Quadruple Differential Line Driver With +/-15-kV IEC ESD Protection
- AM26LV32E Low-Voltage High-Speed Quadruple Differential Line Receiver With +/-15-kV IEC ESD
for LVDS i have found this Pair
is either a good choice?
or are there any other better suited parts?
additionally i have found this Info:
- TI Designs: TIDA-060017 Transmitting SPI Signals Over LVDS Interface Reference Design
- Blog - Get Connected: How to extend an SPI bus through a differential interface
i hope you can give me some tips :-)
