The ADV7150 is a single CMOS chip designed for high-performance, color graphics workstations. It integrates multiple graphic functions and supports 24-bit true color operation with a maximum screen update rate of 220 MHz. The ADV7150 implements 30-bit true color in 24-bit frame buffer designs and also supports other modes, including 15-bit true color and 8-bit pseudo or indexed color. The pseudo color can be achieved using the red, green, or blue input pixel ports.
The ADV7150 is a complete analog‑output video RAM‑DAC on a single CMOS monolithic chip, designed for high‑performance color graphics workstations. It provides 24‑bit true‑color operation at up to 220 MHz pixel clock and supports additional modes such as 15‑bit true color and 8‑bit pseudo color.
The device is packaged in a 160‑lead plastic QFP and includes on‑chip clock control, palette RAM, and standard MPU I/O interfaces. Detailed electrical specifications, timing characteristics, and absolute maximum ratings are provided for designers integrating the part into video systems.
