Note: OBUFDS_DPHY_COMP is not available on the following devices: VC1902, VC1802, VM1802, VM1302, and VM1402.
Table 1. OBUFDS_DPHY and OBUFDS_DPHY_COMP Attributes
Attribute Values Description
IOSTANDARD MIPI_DPHY Assigns an I/O standard to the element.
Table 2. OBUFDS_DPHY and OBUFDS_DPHY_COMP Ports
Port I/O Description
O Output Output connected directly to P-side top-level output port.
OB Output Output connected directly to N-side top-level output port.
HSTX_I Input Data input from the p-side NIBBLESLICE (OBUFDS_DPHY) or n-side NIBBLESLICE (OBUFDS_DPHY_COMP) (HS TX)

For OBUFDS_DPHY_COMP, HSTX_I must be connected to O1 (XPHY). XPHY data from the D1 input is serialized to differential outputs. A logical Low results in O being Low and OB being High.

HSTX_T Input Tristate control input (HS TX)
LPTX_I_N Input Data input (LP TX)
LPTX_I_P Input Data input (LP TX)
LPTX_T Input Tristate control input (LP TX)
