DUAL CHANNEL, 12-BITS, 125/105/80/65 MSPS ADC WITH DDR LVDS/CMOS OUTPUTS

• Radar Systems

• Maximum Sample Rate: 125 MSPS

• 12-Bit Resolution with No Missing Codes

ADS62P2X is a dual channel 12-bit A/D converter

• 95 dB Crosstalk

family with maximum sample rates up to 125 MSPS.

• Parallel CMOS and DDR LVDS Output Options

It

combines

high

performance

and

low

power

• 3.5 dB Coarse Gain and Programmable Fine

consumption in a compact 64 QFN package. Using

Gain up to 6 dB for SNR/SFDR Trade-Off

an internal sample and hold and low jitter clock

buffer, the ADC supports high SNR and high SFDR at

• Digital Processing Block with:

high input frequencies. It has coarse and fine gain

Offset Correction

options

that

can

be

used

to

improve

SFDR

–

Fine Gain Correction, in Steps of 0.05 dB

performance at lower full-scale input ranges.

–

Decimation by 2/4/8

ADS62P2X includes a digital processing block that

–

Built-in and Custom Programmable 24-Tap

consists of several useful and commonly used digital

functions such as ADC offset correction, fine gain

Low-/High-/Band-Pass Filters

correction (in steps of 0.05 dB), decimation by 2,4,8

• Supports Sine, LVPECL, LVDS, and LVCMOS

and in-built and custom programmable filters. By

Clocks and Amplitude Down to 400 mVPP

default, the digital processing block is bypassed, and

• Clock Duty Cycle Stabilizer

its functions are disabled.

• Internal Reference; Supports External

Two output interface options exist – parallel CMOS

Reference also

and DDR LVDS (Double Data Rate). ADS62P2X

• 64-QFN Package (9mm × 9mm)

includes

internal

references

while

traditional

reference pins and associated decoupling capacitors

• Pin Compatible 14-Bit Family (ADS62P4X)

have been eliminated. Nevertheless, the device can

also be driven with an external reference. The device

is specified over the industrial temperature range

• Wireless Communications Infrastructure

(–40

°C to 85°C).

• Software Defined Radio

• Power Amplifier Linearization

• 802.16d/e

• Test and Measurement Instrumentation

• High Definition Video

• Medical Imaging
