CXA3026AQ
8-bit 140MSPS Flash A/D Converter
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.
48 pin QFP (Plastic)
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
LEAD TREATMENT: PALLADIUM PLATING
Structure
Bipolar silicon monolithic IC
Applications
• Magnetic recording (PRML)
• Communications (QPSK, QAM)

2. Straight mode (See Application Circuits1- (4), (5) and (6).)
Set the SELECT pin to GND for this mode. In this mode, data output can be obtained in accordance with the
clock frequency applied to the A/D converter for applications which use the clock applied to the A/D converter
as the system clock.
The A/D converter can operate at Fc (min.) = 100MSPS in this mode.
Digital input level and supply voltage settings
The logic input level for the CXA3026AQ supports ECL, PECL and TTL levels.
The power supplies (DVEE3, DGND3) for the logic input block must be set to match the logic input (CLK and
RESET signals) level.
