MAX12558ETK+D 数据手册

19-3925; Rev 1; 4/07

Dual, 96Msps, 14-Bit, IF/Baseband ADC

General Description

Features

The MAX12559 is a dual, 3.3V, 14-bit analog-to-digital

converter (ADC) featuring fully differential wideband

track-and-hold (T/H) inputs, driving internal quantizers.

The MAX12559 is optimized for low power, small size,

and high dynamic performance in intermediate frequen-

cy (IF) and baseband sampling applications. This dual

ADC operates from a single 3.3V supply, consuming

only 980mW while delivering a typical 72.2dB signal-to-

noise ratio (SNR) performance at a 175MHz input fre-

quency. The T/H input stages accept single-ended or

differential inputs up to 350MHz. In addition to low oper-

ating power, the MAX12559 features a 0.5mW power-

down mode to conserve power during idle periods.

♦ Direct IF Sampling Up to 350MHz

♦ Excellent Dynamic Performance

73dB/72.2dB SNR at f = 70MHz/175MHz

83.5dBc/78.8dBc SFDR at f = 70MHz/175MHz

♦ 3.3V Low-Power Operation

980mW (Differential Clock Mode)

952mW (Single-Ended Clock Mode)

♦ Fully Differential or Single-Ended Analog Input

♦ Adjustable Differential Analog Input Voltage

♦ 750MHz Input Bandwidth

♦ Adjustable, Internal or External, Shared Reference

♦ Differential or Single-Ended Clock

♦ Accepts 25% to 75% Clock Duty Cycle

♦ User-Selectable DIV2 and DIV4 Clock Modes

♦ Power-Down Mode

A flexible reference structure allows the MAX12559 to

use the internal 2.048V bandgap reference or accept

an externally applied reference and allows the refer-

ence to be shared between the two ADCs. The refer-

ence structure allows the full-scale analog input range

to be adjusted from 0.35V to 1.15V. The MAX12559

provides a common-mode reference to simplify design

and reduce external component count in differential

analog input circuits.

♦ CMOS Outputs in Two’s Complement or Gray

Code

♦ Out-of-Range and Data-Valid Indicators

♦ Small, 68-Pin Thin QFN Package

(10mm x 10mm x 0.8mm)

♦ 12-Bit, Pin-Compatible Version Available

The MAX12559 supports either a single-ended or differ-

ential input clock. User-selectable divide-by-two (DIV2)

and divide-by-four (DIV4) modes allow for design flexibil-

ity and help to reduce the negative effects of clock jitter.

Wide variations in the clock duty cycle are compensated

with the ADC’s internal duty-cycle equalizer (DCE).

CODE

The MAX12559 features two parallel, 14-bit-wide,

CMOS-compatible outputs. The digital output format is

pin-selectable to be either two’s complement or Gray

code. A separate power-supply input for the digital out-

puts accepts a 1.7V to 3.6V voltage for flexible interfac-

ing with various logic levels. The MAX12559 is available

in a 10mm x 10mm x 0.8mm, 68-pin thin QFN package

with exposed paddle (EP), and is specified for the

extended (-40°C to +85°C) temperature range.
