General Description

The MAX1213N is a monolithic, 12-bit, 170Msps ana-

log-to-digital converter (ADC) optimized for outstanding

dynamic performance at high-IF frequencies beyond

300MHz. The product operates with conversion rates

up to 170Msps while consuming only 720mW.

At 170Msps and an input frequency up to 100MHz, the

MAX1213N achieves an 87dBc spurious-free dynamic

range (SFDR) with excellent 67.2dB signal-to-noise

ratio (SNR) that remains flat (within 2dB) for input tones

up to 250MHz. This makes it ideal for wideband appli-

cations such as communications receivers, cable-head

end receivers, and power-amplifier predistortion in cel-

lular base-station transceivers.

The MAX1213N operates from a single 1.8V power sup-

ply. The analog input is designed for AC-coupled differ-

ential or single-ended operation. The ADC also features

a selectable on-chip divide-by-2 clock circuit that

accepts clock frequencies as high as 340MHz. A low-

voltage differential signal (LVDS) sampling clock is

recommended for best performance. The converter pro-

vides LVDS-compatible digital outputs with data format

selectable to be either two’s complement or offset binary.

The MAX1213N is available in a 68-pin QFN package

with exposed paddle (EP) and is specified over the

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

See the Pin-Compatible Versions table for a complete

selection of 8-bit, 10-bit, and 12-bit high-speed ADCs in

this family.
