1 to N MIPI CSI-2/DSI Duplicator

Duplicate one MIPI RX channel to one or two MIPI TX channels

Many new applications such as virtual reality, augmented reality, and digital cameras require expansion of the number of camera or display interface on application processors (AP). This often occurs when there is either not enough ports or some ports are used for other purposes on the AP.

The Lattice Semiconductor 1 to N MIPI® CSI-2/DSI Duplicator reference design with CertusPro™-NX devices can be configured for one to four duplicated outputs.

CrossLink and CrossLink-NX - The Lattice CrossLink and CrossLink-NX has two MIPI Hardened macro IPs, which can be used as MIPI TX or RX module (D-PHY Hardened IP). The TX and RX modules can also be realized by a soft macro utilizing general DDR modules (D-PHY Soft IP).

CertusPro-NX - The Lattice CertuPro-NX has MIPI D-PHY Soft IPs can be configured as MIPI transmitter or receiver utilizing the general DDR modules.

Features

  • RX channel can have one, two, or four lanes
  • Number of TX lanes can be one, two, or four. This is independent from the number of RX lanes
  • CrossLink and CrossLinkPlus:
    • Maximum RX bandwidth is 1.5 Gbps per lane using D-PHY Hard IP and 1.2 Gbps per lane using D-PHY Soft IP
  • CrossLink-NX:
    • Maximum RX bandwidth is 2.5 Gbps per lane using D-PHY Hardened IP, 1.5 Gbps per lane using D-PHY Soft IP
    • Maximum TX bandwidth is 2.5 Gbps per lane using D-PHY Hardened IP and 1.5 Gbps per lane using D-PHY Soft IP
  • CertusPro-NX:
    • Maximum RX/TX bandwidth is 1.5 Gbps per lane using D-PHY Soft IP
