Detailed Design Procedure

The application shown in MEMs Module Switching for LIDAR demonstrates how to incorporate the TMUX7612-Q1 switch to expand the system MEMs module density without adding additional lasers, lenses, or controllers. The tilt angle analog control is passed through the switch to the MEMs modules. The angles can then be swept in the X and Y direction. Once the sweeps are complete, the TMUX7612-Q1 will switch to the next set of modules and repeat this process until a full image of the environment is obtained. This device can support 1.8 V logic signals on the control input, allowing the device to interface with low logic controls of an FPGA or MCU. The TMUX7612-Q1 can be operated without any external components except for the supply decoupling capacitors. The select pins have an internal pull-down resistor to prevent floating input logic. The TMUX7612-Q1 supports asymmetric supply rails within a 50 V differential, and down to 4.5 V on the positive supply. For this design, the signal range must stay within the supply rails of the device.
