Context 1
... interface is developed as a unidirectional (write only) serial peripheral interface (SPI) protocol on a physical layer using an RS-422 transceiver. As defined in the satellite requirements, this interface provides two links, one nominal and one redundant, which simultaneously transmit the data packets (Figure 5a). The physical layer uses the transceiver Texas Instruments AM26C31 already used and validated in the HEPD-01 CPU board. ...

... physical layer uses the transceiver Texas Instruments AM26C31 already used and validated in the HEPD-01 CPU board. The RS-422 interfaces are characterized by a nominal clock of 6 (± 0.5%) MHz, and the communication timing with a transmission interval T1 of 5.5 ms (MAX) and an inactivity period T2 of minimum 10us, as visible in the timing diagram in Figure 5b. ...
