14-BITS, 125/105/80/65 MSPS ADC WITH DDR LVDS/CMOS OUTPUTS

•

Radar Systems

FEATURES

•

Maximum Sample Rate: 125 MSPS

DESCRIPTION

•

14-Bit Resolution with No Missing Codes

ADS6145/ADS6144/ADS6143/ADS6142 (ADS614X)

are a family of 14-bit A/D converters with sampling

frequencies up to 125 MSPS. The high performance

and low power consumption of the ADS614X are

combined in a compact 32 QFN package. An internal

high bandwidth sample and hold and a low jitter clock

buffer help to achieve high SNR and high SFDR even

at high input frequencies.

3.5 dB Coarse Gain and up to 6 dB

Programmable Fine Gain for SNR/SFDR

Trade-Off

•

Parallel CMOS and Double Data Rate (DDR)

LVDS Output Options

Supports Sine, LVCMOS, LVPECL, LVDS Clock

Inputs, and Clock Amplitude Down to 400

mV_PP

The ADS614X feature coarse and fine gain options to

improve SFDR performance at lower full-scale analog

input ranges.

•

Clock Duty Cycle Stabilizer

Internal Reference with Support for External

Reference

The digital data outputs are either parallel CMOS or

DDR (Double Data Rate) LVDS. Several features

exist to ease data capture such as — controls for

output clock position and output buffer drive strength,

programmability.

•

3.3-V Analog and 1.8-V to 3.3-V Digital Supply

32-QFN Package (5 mm × 5 mm)

The output interface type, gain, and other functions

are programmed using a 3-wire serial interface.

Alternatively, some functions are configured using

dedicated parallel pins so the device powers up to the

desired state.

Pin Compatible 12-Bit Family (ADS612X)

APPLICATIONS

The ADS614X include internal references while

eliminating traditional reference pins and associated

external decoupling. External reference mode is also

supported.
