Sine Wave Single Ended Encoder to Differential Interpolator Input

Hi I have a high resolution encoder that produces two 1V p-p sine waves 90 degrees out of phase and an interpolator box whoes input is 1V p-p but differential.

Could anyone comment on the best way to connect these in a low noise environment? I am using the system to provide closed loop feedback to a separate gearbox/servo/sncoder system.

Most of the previous topics discuss single ended TTL to Differential TTL

I have heard from some just to ground the - terminal on the differential side. I guess would cause a difference in the line reciever (26LS32) stage of the inverter and the signal would not be rejected. It would then proceed via amplification to the ADC.

Thanks for any help
