Patent Images
1. Apparatus connecting two MIPI signal sources, each defining MIPI conforming clock and data lanes to an MIPI interface, the apparatus comprising:
- an analog switch with two inputs, one connected to each of the two MIPI signal sources, one output connecting to the MIPI interface, and a control signal that defines the state of the analog switch;
a controller comprising a first gate with at least one input connected to at least one of the clock lane signals from one signal source, and a second gate with at least one input connected to at least one of the clock lane signals from the other signal source;
wherein each gate defines a threshold, wherein the first and the second gates respond when their thresholds are exceeded;
the controller further comprising a latch that outputs the control signal to the analog switch.

Abstract
An MIPI interface is connected to two sensor sources that each may be transferring both high and low speed information, typically video information in the high speed state. The clock signals are monitored and when one of the clock signals exceed a threshold, an analog switch between the MIPI interface and the sensors, may connect the other source to the MIPI interface.

5. A method for connecting two MIPI signal sources, each defining MIPI conforming clock and data lanes to an MIPI interface, the method comprising the steps of:
-
comparing the clock lane signals from the two MIPI signal sources to a threshold; and
if the threshold is exceeded by at least one of the clock lane signals from one MIPI source,connecting the clock lane and data lane signals from the other MIPI signal source to an MIPI interface. - View Dependent Claims (6, 7, 8)
