CXD2301Q

8-bit 30MSPS Video A/D Converter with Built-in Amplifier/Clamp

Description

The CXD2301Q is an 8-bit CMOS A/D converter

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.

32 pin QFP (Plastic)

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.
