DVEVM Featured Products

The Digital Video Evaluation Module (DVEVM) enables developers to start immediate evaluation of DaVinci™ processors and begin building digital video applications such as videophones, automotive infotainment, digital still cameras, streaming media, IP set-top boxes, video security systems and digital video products that have yet to be invented.

Digital Audio/Video applications using TI’s new TMS320DM6443 and TMS320DM6446 DSPs will benefit from highly efficient, small size and feature-rich power management solutions such as our TPS62xxx and TPS54xxx Low-Power DC/DC Converters and TPS7xxx LDO Regulators. Combined with a complete portfolio of Supply Voltage Supervisors (SVS) and Battery Management Products, the best power designs can be achieved using Texas Instruments Power Management.
