CXA3506R

CXA3506R 3-channel 8-bit 120MSPS A/D Converter Amplifier PLL Description The CXA3506R is a 3-channel 8-bit 120MSPS A/D converter with built-in amplifier and PLL developed for LCD projectors and LCD monitors. The CXA3506R inputs RGB graphics signals from personal computers or others. After the input levels are controlled, the A/D conversion is performed with a clock generated by PLL. The digital output levels are compatible with TTL. This IC operates at a maximum conversion rate of 120MHz, and can support up to XGA. Control register supports both I2C and 3-wire bus. Features Supply voltage: 5V, 3.3V Power consumption: 1.7W typ. (120MSPS) 144-pin LQFP 3-ch AMP and PLL eliminate design time for mutual connections.
