ADC11C125 11-Bit, 125 MSPS, 1.1 GHz Bandwidth A/D Converter with CMOS Outputs

Check for Samples: ADC11C125

FEATURES

DESCRIPTION

The ADC11C125 is

a high-performance CMOS

•

1.1 GHz Full Power Bandwidth

Internal Sample-and-Hold Circuit

Low Power Consumption

analog-to-digital converter capable of converting

analog input signals into 11-Bit digital words at rates

up to 125 Mega Samples Per Second (MSPS). This

converter uses a differential, pipelined architecture

with digital error correction and an on-chip sample-

and-hold circuit to minimize power consumption and

the external component count, while providing

excellent dynamic performance. A unique sample-

and-hold stage yields a full-power bandwidth of 1.1

GHz. The ADC11C125 operates from dual +3.3V and

+1.8V power supplies and consumes 608 mW of

power at 125 MSPS.

•

Internal Precision 1.0V Reference

Single-Ended or Differential Clock Modes

Clock Duty Cycle Stabilizer

Dual +3.3V and +1.8V Supply Operation

Power-Down and Sleep Modes

Offset Binary or 2's Complement Output Data

Format

•

Pin-Compatible: ADC14155, ADC12C170,

ADC11C170

The separate +1.8V supply for the digital output

interface allows lower power operation with reduced

noise. A power-down feature reduces the power

consumption to 5 mW while still allowing fast wake-up

time to full operation. In addition there is a sleep

feature which consumes 50 mW of power and has a

faster wake-up time.

48-pin WQFN Package, (7x7x0.8mm, 0.5mm

Pin-Pitch)

APPLICATIONS

•

High IF Sampling Receivers

Wireless Base Station Receivers

Power Amplifier Linearization

Multi-Carrier, Multi-Mode Receivers

Test and Measurement Equipment

Communications Instrumentation

Radar Systems

The differential inputs provide a full scale differential

input swing equal to 2 times the reference voltage. A

stable 1.0V internal voltage reference is provided, or

the ADC11C125 can be operated with an external

reference.

Clock mode (differential versus single-ended) and

output data format (offset binary versus 2's

complement) are pin-selectable.

duty cycle

stabilizer maintains performance over a wide range of

input clock duty cycles.
