The programmable differential output driver uses a switched-current mode type shown in Figure 46. A tail current of 4, 6, or 8 mA (nominal) can be programmed to achieve VOD swing compatible with AC-coupled LVDS, CML, or LVPECL receivers, respectively, across a 100-Ω differential termination. The differential output driver is ground-referenced (similar to an HCSL driver), meaning the differential output has a low common-mode voltage (VOS).
The differential driver has internal biasing, so external pullup or pulldown resistors should not be applied. The differential output should be interfaced through external AC-coupling to a differential receiver with proper input termination and biasing.
