AL875

High Speed Triple 8-bit ADC

Applications

− LCD/PDP Monitors

− LCD Projectors

− Other Flat Panel Displays

− High-end Video/Graphics Processing

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

• Support display resolution up to 1280x1024 at 60Hz

• 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
