DESCRIPTION

ADS5546 is a high performance 14-bit, 190-MSPS

A/D converter. It offers state-of-the art functionality

and performance using advanced techniques to

minimize board space. Using an internal sample and

hold and low jitter clock buffer, the ADC supports

both high SNR and high SFDR at high input

frequencies. It features programmable gain options

that can be used to improve SFDR performance at

lower full-scale analog input ranges.

Double Data Rate (DDR) LVDS and Parallel

CMOS Output Options

•

Programmable Gain up to 6 dB for SNR/SFDR

Trade-Off at High IF

Reduced Power Modes at Lower Sample

Rates

Supports input clock amplitude down to 400

mV_PP

In a compact 48-pin QFN, the device offers fully

differential LVDS DDR (Double Data Rate) interface

while parallel CMOS outputs can also be selected.

Flexible output clock position programmability is

available to ease capture and trade-off setup for hold

times. At lower sampling rates, the ADC can be

operated at scaled down power with no loss in

performance. ADS5546 includes an internal

reference, while eliminating the traditional reference

pins and associated external decoupling. The device

also supports an external reference mode.

•

Clock Duty Cycle Stabilizer

No External Reference Decoupling Required

Internal and External Reference Support

Programmable Output Clock position to ease

data capture

•

3.3-V Analog and Digital Supply

48-QFN Package (7 mm × 7 mm)

APPLICATIONS

•

The device is specified over the industrial

temperature range (-40°C to 85°C).

Wireless Communications Infrastructure

Software Defined Radio
