sn65hvd78 data transmission problem

Other Parts Discussed in Thread: SN65HVD78

Hello all,

In my project, i use sn65hvd78 rs485 tranciever to transmit and receive 15mhz clock and data signals. I use one sn65hvd78 to transmit and one for receive. I use a 5 meter CAT5 cable. The problem is that sometimes the data comes deformed. I wonder the reason of it. I use a 100 ohm resistor between A and B nodes in receiver side. I used no more components such as capacitors. I also wonder if there is more efficient way of sending high frequency data and clock signals far away.

Thank you,
