4 / 38 page  CS8411 CS8412 4 DS61F1 DIGITAL CHARACTERISTICS - RS422 RECEIVERS (RXP, RXN pins only; VD+ = 5V ± 10%) Notes: 4. VCM - Input Common Mode Range 5. When the receiver inputs are configured for singe ended operation (e.g. consumer configuration) the signal amplitude must exceed 400m Vp-p for the differential voltage on RXP to RXN to exceed 200mV. This represents twice the minimum signal level of 200 mVp-p specified in CP340/1201 and IEC-958 (which are not RS-422 compliant).
