VT1632A DVI Transmitter

As digital devices continue there spread into our homes, cars, workplaces etc. new requirements for new display solutions are demanding different display connections. The VIA VT1632A DVI transmitter through Transition Minimized Differential Signaling (TMDS) enables high speed connections to the latest display solutions over distances not possible with legacy solutions overcoming many issues such as noise generation, power consumption, and noise immunity. Moreover the VIA VT1632A DVI Transmitter enables a vast improvement in the amount and quality of video data that can be transferred between devices enabling higher resolutions, lower power requirements, and universal connectivity.

The VIA VT1632A DVI transmitter is designed for compliance with DVI Revision 1.0 (DVI is backwards compliant with VESA P&D and DFP) and supports display solutions ranging from VGA to UXGA resolutions (25 to 165Mpps) with a single link interface. Three TMDS data channels send data at up to 1.65Gbps per channel. The VIA VT1632A also supports DVI’s dual-link capability for data transfer rates up to 330Mbps.

The VIA VT1632A has a highly flexible interface with either a 12-bit mode (1/2 pixel per clock edge) or 24-bit mode 1 pixel per clock input for true color (16.7 Million) support. In 24-bit mode, the VT1632A supports single or dual edge clocking. The VIA VT1632A also supports dual edge single clocking or single edge dual clocking in 12-bit mode. Supporting receiver and Hot Plug Detection, the VIA VT1632A can be programmed through an I2S interface.
