Product Information

Back to top
The AL875 from Averlogic is a high-speed triple 8-bit monolithic analog-to-digital converter (ADC) designed for digitizing RGB graphics/video signal or other applications. The AL875's 110 MHz conversion rate can support display resolution up to 1280x1024 at 60Hz. The AL875 accepts 0.7~2.5V analog input range without using pre-amplifiers which may reduce the overall S/N ratio. Digitized data is piped at the full clock rate to the 24-bit output port. The AL875 uses 3.3V power with 5V tolerant I/O and low power dissipation. In addition, the active video (horizontal and vertical) starting and ending positions in the AL875 are also detected to ensure that the whole picture is fitted into the displayable region of the screen. Through an I2C interface, the AL875 is fully programmable to support various video resolutions.
