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

FEATURES

DESCRIPTION

•

Maximum Sample Rate: 125 MSPS

14-Bit Resolution with No Missing Codes

95 dB Crosstalk

ADS62P4X is a dual channel 14-bit A/D converter

family with maximum sample rates up to 125 MSPS.

It combines high performance and low power

consumption in a compact 64 QFN package. Using

an internal sample and hold and low jitter clock

buffer, the ADC supports high SNR and high SFDR at

high input frequencies. It has coarse and fine gain

options that can be used to improve SFDR

performance at lower full-scale input ranges.

Parallel CMOS and DDR LVDS Output Options

3.5 dB Coarse Gain and Programmable Fine

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

•

Digital Processing Block with:

–

Offset Correction

Fine Gain Correction, in Steps of 0.05 dB

Decimation by 2/4/8

ADS62P4X includes a digital processing block that

consists of several useful and commonly used digital

functions such as ADC offset correction, fine gain

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

and in-built and custom programmable filters. By

default, the digital processing block is bypassed, and

its functions are disabled.

Built-in and Custom Programmable 24-Tap

Low-/High-/Band-Pass Filters

•

Supports Sine, LVPECL, LVDS and LVCMOS

Clocks and Amplitude Down to 400 mV_PP

•

Clock Duty Cycle Stabilizer

Two output interface options exist – parallel CMOS

and DDR LVDS (Double Data Rate). ADS62P4X

includes internal references while traditional

reference pins and associated decoupling capacitors

have been eliminated. Nevertheless, the device can

also be driven with an external reference. The device

is specified over the industrial temperature range

(–40°C to 85°C).

Internal Reference; Supports External

Reference also
