Description
The AL875 is a high-speed triple 8-bit
monolithic analog-to-digital converter
(ADC) designed for digitizing RGB
graphics/video signal or other applications.
Its 110 MHz conversion rate can support
display resolution up to 1280x1024 at
60Hz.
• High speed 8-bit ADC up to 110MHz encode rate

• Low power dissipation (0.8W typical at 3.3V,
110MHz)
• 0.6~2.0V p-p analog input range
• 10k~1MHz HSYNC locking range
• Full programmability via I2C interface
• Support automatic screen positioning
• Support automatic clock phase adjustment
• TTL compatible digital inputs and outputs
• High impedance tri-state output
• Power-down mode
• Single 3.3 volt power with 5 volt tolerant I/O
• 100-pin 14x20 mm PQFP package

The AL875 is a high-speed triple 8-bit monolithic analog-to-digital converter (ADC) designed for
digitizing RGB graphics/video signal or other applications. Its 110 MHz conversion rate can
support display resolution of up to 1280x1024 at 60Hz refresh rate.
The AL875 accepts 0.6~2.0V 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.
The sampling clock is provided by an external clock source, usually a PLL, which multiplies the
frequency of the input reference clock (usually a HSYNC signal) to generate the sampling clock.
The AL875 provides a programmable PLL divider up to 4096.
In addition, the input active horizontal and vertical starting and ending positions can be detected to
ensure that the whole picture fits into the displayable region of the screen. Through an I2C interface,
the AL875 is fully programmable to support various graphic resolutions.
Analog graphic/video signals such as RGB, YCbCr and YPbPr can be digitized by the AL875. The
digitized data can then be processed by the AL250/251 line doubler, AL300 LCD controller, or
other proprietary designs for various applications.
