1.8V, 10-Bit, 250Msps Analog-to-Digital Converter

with LVDS Outputs for Wideband Applications

General Description

Features

The MAX1124 is a monolithic 10-bit, 250Msps analog-

to-digital converter (ADC) optimized for outstanding

dynamic performance at high IF frequencies up to

500MHz. The product operates with conversion rates of

up to 250Msps while consuming only 477mW.

♦ 250Msps Conversion Rate

♦ SNR = 56.8dB/55.5dB at f = 100MHz/500MHz

♦ SFDR = 71dBc/63.8dBc at f = 100MHz/500MHz

♦ NPR = 54.8dB at f

= 28.8MHz

NOTCH

At 250Msps and an input frequency of 100MHz, the

MAX1124 achieves a spurious-free dynamic range

(SFDR) of 71dBc. Its excellent signal-to-noise ratio

(SNR) of 57.1dB at 10MHz remains flat (within 1dB) for

input tones up to 500MHz. This makes the MAX1124

ideal for wideband applications such as digital predis-

tortion in cellular base-station transceiver systems.

♦ Single 1.8V Supply

♦ 477mW Power Dissipation at 250Msps

♦ On-Chip Track-and-Hold and Internal Reference

♦ On-Chip Selectable Divide-by-2 Clock Input

♦ LVDS Digital Outputs with Data Clock Output

♦ Evaluation Kit Available (Order MAX1124EVKIT)

The MAX1124 requires a single 1.8V supply. The ana-

log input is designed for either differential or single-

ended operation and can be AC- or DC-coupled. The

ADC also features a selectable on-chip divide-by-2

clock circuit, which allows the user to apply clock fre-

quencies as high as 500MHz. This helps to reduce the

phase noise of the input clock source. A differential

LVDS sampling clock is recommended for best perfor-

mance. The converter’s digital outputs are LVDS com-

patible, and the data format can be selected to be

either two’s complement or offset binary.

exposed paddle (EP) and is specified over the industri-

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

Pin Configuration

For pin-compatible, lower speed versions of the

MAX1124, refer to the MAX1122 (170Msps) and the

MAX1123 (210Msps) data sheets. For a pin-compatible

8-bit version of the MAX1124, refer to the MAX1121

data sheet.
