| Input |
| Receiver type | SN75ALS175 quad differential receiver |
| Configuration | 8 channels. Each channel consists of PhaseA input, PhaseB input and Index input; each input is selectable as single-ended or differential. Differential: PhaseA, PhaseB and Index (+) inputs at the user connector are routed to the (+) inputs of differential receiver. PhaseA, PhaseB and Index (–) inputs at the user connector are routed to the (–) inputs of the differential receiver. Single-ended: PhaseA, PhaseB and Index (+) inputs at the user connector are routed to the (+) inputs of the differential receiver. PhaseA, PhaseB and Index (–) inputs at the user connector are left floating. The (–) inputs of the differential receiver are routed to the +3 V reference. |
