2:1 MIPI switch for 2x data + 1x clock D-PHY, or 2x C-PHY

2:1 MIPI switch for 2x data + 1x clock D-PHY, or 2x C-PHY

2020-11-25
Diodes-MIPI-PI3WVR628

Called PI3WVR628, it is a six channel single-pole, double-throw (SPDT) switch supporting two data lanes plus a clock lane for D-PHY signals, or two lanes for C-PHY signals.

Optimisation is for rapid switching between high-speed (HS) and low-power (LP) MIPI physical interfaces – supporting changing from a low data rate D-PHY camera to a high data rate C-PHY camera.

“To support high speed D-PHY/C-PHY applications, the device has a 6GHz bandwidth, low crosstalk and low Ron,” claimed the company. Figures are -35dB at 2.25GHz and 5.0Ω.


Projected performance is up to 3.5Gsample/s C-PHY and up to 4.5Gbit/s D-PHY.

Packaging is 1.7mm x 2.4mm X1-LGA2417-24 LGA with 0.4mm pitch – small for wearables and phones.

Operation is across 1.5V to 3.6V and multiple I/O voltage rails.

This part has three differential channels. There are similar parts with five differential channels, and other similar parts rated at 3.5GHz rather than 6GHz.
