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.
