General Description

The MAX1213 is a monolithic, 12-bit, 170Msps analog-

to-digital converter (ADC) optimized for outstanding

dynamic performance at high-IF frequencies up to

300MHz. The product operates with conversion rates

up to 170Msps while consuming only 788mW.

At 170Msps and an input frequency up to 250MHz, the

MAX1213 achieves a spurious-free dynamic range

(SFDR) of 72.9dBc. Its excellent signal-to-noise ratio

(SNR) of 65.8dB at 10MHz remains flat (within 2dB) for

input tones up to 250MHz. This ADC yields an excellent

low-noise floor of -68dBFS, which makes it ideal for

wideband applications such as cable head-end

receivers and power-amplifier predistortion in cellular

base-station transceivers.

The MAX1213 requires a single 1.8V supply. The analog

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 frequencies as high

as 340MHz. This helps to reduce the phase noise of the

input clock source. A low-voltage differential signal

(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.

The MAX1213 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.
