CXA3246Q
8-bit 120MSPS Flash A/D Converter
Description
The CXA3246Q is an 8-bit high-speed flash A/D
converter capable of digitizing analog signals at the
maximum rate of 120MSPS. ECL, PECL or TTL can
be selected as the digital input level in accordance
with the application. The TTL digital output level
allows 1: 2 demultiplexed output.
Features
• Differential linearity error: ±0.5LSB or less
• Integral linearity error: ±0.5LSB or less
• High-speed operation with a maximum conversion
rate of 120MSPS
• Low input capacitance: 10pF
• Wide analog input bandwidth: 250MHz
• Low power consumption: 500mW
• 1: 2 demultiplexed output
• 1/2 frequency-divided clock output
(with reset function)
• Compatible with ECL, PECL and TTL digital input
levels
• TTL output "H" levels: 2.8V (Typ.)
• +3.3V line CMOS IC direct connecting available
• Single +5V power supply operation available
• Surface mounting package (48-pin QFP)
