ADC08D1020

Low Power, 8-Bit, Dual 1.0 GSPS or Single 2.0 GSPS A/D

Converter

General Description

Features

The ADC08D1020 is a dual, low power, high performance,

CMOS analog-to-digital converter that builds upon the AD-

C08D1000 platform. The ADC08D1020 digitizes signals to 8

bits of resolution at sample rates up to 1.3 GSPS. It has ex-

panded features compared to the ADC08D1000, which in-

clude a test pattern output for system debug, a clock phase

adjust, and selectable output demultiplexer modes. Consum-

ing a typical 1.6 Watts in non-demultiplex mode at 1 GSPS

from a single 1.9 Volt supply, this device is guaranteed to have

no missing codes over the full operating temperature range.

The unique folding and interpolating architecture, the fully dif-

ferential comparator design, the innovative design of the in-

ternal sample-and-hold amplifier and the calibration schemes

enable a very flat response of all dynamic parameters beyond

Nyquist, producing a high 7.4 Effective Number of Bits

(ENOB) with a 498 MHz input signal and a 1 GHz sample rate

while providing a 10⁻¹⁸Code Error Rate (C.E.R.) Output for-

matting is offset binary and the Low Voltage Differential Sig-

naling (LVDS) digital outputs are compatible with IEEE

1596.3-1996, with the exception of an adjustable common

mode voltage between 0.8V and 1.2V.

—

Each converter has a selectable output demultiplexer which

feeds two LVDS buses. If the 1:2 demultiplexed mode is se-

lected, the output data rate is reduced to half the input sample

rate on each bus. When non-demultiplexed mode is selected,

that output data rate on channels DI and DQ are at the same

rate as the input sample clock. The two converters can be

interleaved and used as a single 2 GSPS ADC.

Applications

Direct RF Down Conversion

Digital Oscilloscopes

The converter typically consumes less than 3.5 mW in the

Power Down Mode and is available in a leaded or lead-free

128-lead, thermally enhanced, exposed pad, LQFP and op-

erates over the Industrial (-40°C ≤ T_A≤ +85°C) temperature

range.
