Diodes Incorporated has released the PI3WVR648GEAEX five-channel MIPI 2: 1 switch, which is capable of exchanging a physical layer that conforms to the C-PHY or D-PHY serial interface, as defined by industry standard specifications for smartphones and image sensors. Show in mobile app. The device supports both HS and LP MIPI, enabling connected modules to switch between these standards without causing delays or signal degradation. The device provides fast switching between five of the ten channels in a single-channel double-throw configuration. 2: 1 multiplexing can quickly switch between HS and LP MIPI physical interfaces. Typical usage is to connect two MIPI-compatible devices to a single module with a C-PHY or D-PHY interface, such as a multi-camera smartphone. PI3WVR648GEAEX supports four data channels with one clock channel in D-PHY or three data channels in C-PHY, and can support up to 4.5Gbps (D-PHY) and 3.5Gsps (C-PHY) through a complete module ) Data rate. 6 GHz bandwidth, -28dB low crosstalk and 2.25 GHz -23dB isolation. The device can switch between HS and LP PHY specifications with a maximum propagation delay of only 0.25ns. It operates from a supply voltage of 1.5V to 5V and has a 5Ω on-resistance for HS and LP MIPI signals.
