ADC08D1520

Low Power, 8-Bit, Dual 1.5 GSPS or Single 3.0 GSPS A/D

Converter

General Description

Features

The ADC08D1520 is a dual, low power, high performance

CMOS analog-to-digital converter that builds upon the

ADC08D1500 platform. The ADC08D1520 digitizes signals to

8 bits of resolution at sample rates up to 1.7 GSPS. It has

expanded features compared to the ADC08D1500, 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 1.0 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 self-calibration

scheme enable a very flat response of all dynamic parameters

beyond Nyquist, producing a high 7.4 Effective Number of Bits

(ENOB) with a 748 MHz input signal and a 1.5 GHz sample

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

formatting is offset binary and the Low Voltage Differential

Signaling (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 select-

ed, the output data rate on channels DI and DQ is at the same

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

interleaved and used as a single 3 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-pin, thermally enhanced, exposed pad, LQFP and oper-

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

range.
