I have a system where I need to collect position data from a differential encoder. I know there is an option to do this using a Cdaq chassis with a NI 9411 Module but it would require me to reconfigure my system. Write now I have available PCI slots in the pc. My question is, is there an available PCI or PCIe differential Digital Input card available?

Would an IC like the 26LS32 be an option ?
Do you really need the inverted signals ?

Right now I've been getting away with using a Encoder Anti Dithering Module from BEI. To transform the differential feedback signal to a RSE signal so the TTL driver can detect the pulses. However I have also had to incorporate digital filtering in software due to noise and jitter due to vibrations in the system. I'm hoping a differential input module with help me eliminate the BEI Module an help with the jitter. I'm not familar with the 26LS32 IC, I'm assuming it is a similar device as the BEI Module I'm currently using.
