SN75DPHY440SS: SN75DPHY440SS Max. datarate and supported clock mode

Thanks a lot, David

Yes, discontinuous mode is when clock goes into LP11 during the same time window as the data lanes. In continuous mode the clock is free running without any LP transitions.

Do you think it supports both mode or only discontinuous mode?

Continuous mode means HS operational mode? If this is the case, DPHY440 supports both mode.

Thanks

Hi,

Continuous mode means that the clock lane is constantly in HS mode(free running clock), it never enters LP mode. While the data lanes enter LP mode as normal. Below diagram shows the clock in continuous mode while the data lanes enters LP mode.

Thanks for the clarification. If you want the clock to be in HS mode only, please write to the following registers.

(Address, Data)

(0x50, 0x10), // HS TX path Override enable
(0x51, 0x10), // HS TS path enable
(0x61, 0x0F), // Disable LP path.
(0x70, 0x10), // HS RS path Override enable
(0x71, 0x10) // HS RX path enable​

Thanks
David
