Structure

Bipolar silicon monolithic IC

Applications

• Magnetic recording (PRML)

• Communications (QPSK, QAM)

• LCDs

• Digital oscilloscopes

Description

The CXA3026AQ is an 8-bit high-speed flash A/D

converter capable of digitizing analog signals at the

maximum rate of 140MSPS. 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 140MSPS

• Low input capacitance: 21 pF

• Wide analog input bandwidth: 150 MHz

• Low power consumption: 790 mW

• Low error rate

• Excellent temperature characteristics

• 1: 2 demultiplexed output

• 1/2 frequency divided clock output

(with reset function)

• Compatible with ECL, PECL and TTL digital input

levels

• Single +5 V power supply operation available

• Surface mounting package
