Description
The CXD2301Q is an 8-bit CMOS A/D converter
32 pin QFP (Plastic)
for video applications with built-in amplifier/sync-
clamp circuits. A maximum conversion rate of
30MSPS is attained at a low power consumption by
adopting a 2-step parallel system.
Features
• Resolution: 8 bits ±1/2LSB (DL)
• Maximum sampling frequency: 30MSPS
• Low power consumption: 120mW (at 30MSPS
typ.)
(Including reference current)
• Standby function:
0.5mW power consumption in standby
• Amplifier functions: Built-in 3x amplifier (15MHz band),
2-input selector function
provided
• Synchronous clamp function
• Clamp ON/OFF function
• Reference voltage self-bias circuit
• TTL compatible output
• 3V digital interface capability
• Single 5V or dual 4.75/3.3V power supplies
• Low input capacitance: 8pF
• Reference impedance: 330Ω (typ.)
Applications
Wide range of application fields where high-speed
A/D conversion is required such as in the digital
systems of TVs, VCRs, etc.
