1.8V, 8-Bit, 250Msps Analog-to-Digital Converter

with LVDS Outputs for Wideband Applications

General Description

Features

The MAX1121 is a monolithic 8-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 = 48.8dB/48.7dB at f = 100MHz/500MHz

♦ SFDR = 68dBc/63.8dBc at f = 100MHz/500MHz

♦ Single 1.8V Supply

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

MAX1121 achieves a spurious-free dynamic range

(SFDR) of 68dBc. Its excellent signal-to-noise ratio

(SNR) of 48.9dB at 10MHz remains flat (within 0.5dB)

for input tones up to 500MHz. This makes the MAX1121

ideal for wideband applications such as digital predis-

tortion in cellular base-station transceiver systems.

♦ 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 MAX1121 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.
