128-bit video palette offers 16.7 million colors at 1600 x 1280 resolution

The TVP3030 is the latest in a series of advanced Video Interface Palette (VIP) devices from Texas Instruments. The 128-bit device is a performance-enhanced version of the 64-bit TVP3026.

By operating at higher frequencies and integrating a wider pixel bus, the TVP3030 provides more colors at higher resolutions, enabling workstation-like graphics performance for PC Windows accelerators.

Intended for 4 to 8 Mbyte, VRAM-based high-end PC graphics systems, the TVP3030 supports speeds of 175-, 220- and 250-Mhz, enabling 24-bit true color (16.7 million colors) at 1600 x 1280 resolution with an 86 Hz refresh rate, giving superior color rendition and screen clarity.

The TVP3030 is highly integrated, featuring high-speed triple 8-bit DACs, three 256-by-8 color look-up tables, a 64 x 64 x 2 hardware cursor and a programmable pixel multiplexing interface. The device also reduces component count, board space and electrical emissions by integrating dual frequency synthesis Phase Locked Loops (PLL), which can be used to generate pixel clock frequencies up to the device limit.

Like the TVP3026, the TVP3030 features the loop-clock PLL, which simplifies the graphics system design by phase locking the graphics controller and RAMDAC, ensuring proper system timing and allowing maximum VRAM bandwidths.

The TVP3030 is compatible with most industry standard graphics controllers and is available now from TI and its authorized distributors.
