4.3.1. MIPI PPI Clocks

The MIPI PPI connection between the MIPI DSI-2 and MIPI D-PHY IPs includes multiple clock signals from the MIPI D-PHY IP. The lane distribution and packet transmission within the MIPI DSI-2 IP is always performed in the MIPI D-PHY link clock domain.

Guidance on the required connections for each clock is in the following table, where <lane> indicates each of the active lane for the configured MIPI connection and <x> indicates the appropriate LINK number for this MIPI channel on the MIPI D-PHY IP. These signals must be connected directly between the MIPI DSI-2 and MIPI D-PHY IPs.

The frequency of these clocks is determined by the configuration of the MIPI D-PHY IP and the external MIPI interface.

Table 24.  PPI Clock Connections
Signal Name Direction Description
ck_ppi_hs_clk Input High-speed clock on MIPI clock lane. Connect to LINK<x>_ck_ppi_hs_clk on MIPI D-PHY.
ck_ppi_tx_lp_clk Input Low power clock on MIPI clock lane. Connect to LINK<x>_ck_ppi_lp_clk on MIPI D-PHY.
d<lane>_ppi_hs_clk Input High-speed clock on MIPI data lanes. Connect to LINK<x>_d<lane>_ppi_hs_clk on MIPI D-PHY.
d<lane>_ppi_tx_lp_clk Input Low power clock on MIPI data lanes. Connect to LINK<x>_d<lane>_ppi_lp_clk on MIPI D-PHY.
