MIPI PHY switch operates across five lanes for mobile applications
Capable of switching physical layers that comply with either C-PHY or D-PHY serial interfaces, as defined by the industry standard specification for image sensors and cameras in smartphones and displays in mobile applications, the PI3WVR648GEAEX is the latest Mobile Industry Processor Interface (MIPI) PHY switch from Diodes. It is a five-lane model that supports both high speed (HS) MIPI and low power (LP) MIPI.
The PI3WVR648GEAEX allows connected modules to switch between both standards without incurring delays or signal degradation, confirms Diodes.
The PI3WVR648GEAEX offers fast switching among its five lanes, arranged as 10 channels in a single-pole, double-throw configuration. The 2:1 multiplexing allows rapid switching between HS and LP MIPI physical interfaces. A typical use is to connect two MIPI-compliant devices to a single module with a C-PHY or D-PHY interface, such as a multi-camera smartphone.
There is support for four data lanes with one clock lane in D-PHY or three data lanes in C-PHY. The PI3WVR648GEAEX can sustain data rates of up to 4.5Gbits per seconds (D-PHY) with a total bandwidth of 6.0GHz, low crosstalk of -28dB at 2.25GHz, and off-isolation of -23dB at 2.25GHz.
The PI3WVR648GEAEX can switch both HS and LP PHY specifications with a maximum propagation delay of just 0.25 nanoseconds. It operates at a supply voltage of between 1.5 and 5.0V, with a switch-on resistance of 5.0 Ohm for HS and LP MIPI signals.
The PI3WVR648GEAEX is available in a 36-pin WLCSP.
