naps.cores.mipi.dsi_tx.d_phy_lane module

class naps.cores.mipi.dsi_tx.d_phy_lane.DPhyDataLane(*args, src_loc_at=0, **kwargs)

Bases: Elaboratable

A mipi D-Phy Data lane that can handle bidirectional lp data transfer and unidirectional hs transfer.

The sync domain of this module should run at 2x the LP Hold period. Eg if the hold period is 66ns, the sync domain should run at 30 Mhz (these are reasonable values btw). This is needed to be able to sample the incoming data during bus turnaround since there is no fixed phase relation (nyquist).
