1.8V, 10-Bit, 170Msps Analog-to-Digital Converter

with LVDS Outputs for Wideband Applications

General Description

Features

The MAX1122 is a monolithic 10-bit, 170Msps 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 170Msps while consuming only 460mW.

ꢀ 170Msps Conversion Rate

ꢀ SNR = 57.1dB/56.5dB at f = 100MHz/500MHz

ꢀ SFDR = 72dBc/63.5dBc at f = 100MHz/500MHz

ꢀ NPR = 53.7dB at f

= 28.8MHz

NOTCH

At 170Msps and an input frequency of 100MHz, the

MAX1122 achieves a spurious-free dynamic range

(SFDR) of 72dBc. Its excellent signal-to-noise ratio

(SNR) of 57.5dB at 10MHz remains flat (within 1dB) for

input tones up to 500MHz. This makes the MAX1122

ideal for wideband applications such as digital predis-

tortion in cellular base-station transceiver systems.

ꢀ Single 1.8V Supply

ꢀ 460mW Power Dissipation at 170Msps

ꢀ 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 MAX1122 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 340MHz. 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.

Pin Configuration

For pin-compatible, higher speed versions of the

MAX1122, refer to the MAX1123 (210Msps) and the

MAX1124 (250Msps) data sheets. For a higher speed,

pin-compatible 8-bit version of the MAX1122, refer to

the MAX1121 data sheet.
