Dual, 6-Bit, 400Msps ADC with On-Chip,

Wideband Input Amplifier

General Description

Features

The MAX107 is a dual, 6-bit, analog-to-digital converter

(ADC) designed to allow fast and precise digitizing of in-

phase (I) and quadrature (Q) baseband signals. The

MAX107 converts the analog signals of both I and Q

components to digital outputs at 400Msps while achiev-

ing a signal-to-noise ratio (SNR) of typically 37dB with

an input frequency of 125MHz, and an integral nonlin-

earity (INL) and differential nonlinearity (DNL) of 0.25

LSB. The MAX107 analog input preamplifiers feature a

400MHz, -0.5dB, and a 1.5GHz, -3dB analog input

bandwidth. Matching channel-to-channel performance

is typically 0.04dB gain, 0.1LSB offset, and 0.2 degrees

phase. Dynamic performance is 36.7dB signal-to-noise

plus distortion (SINAD) with a 125MHz analog input sig-

nal and a sampling speed of 400MHz. A fully differential

comparator design and encoding circuits reduce out-of-

sequence errors, and ensure excellent metastable per-

formance of only one error per 10¹⁶clock cycles.

ꢀ LVDS Digital Outputs in Two’s Complement

Format

In addition, the MAX107 provides LVDS digital outputs

with an internal 6:12 demultiplexer that reduces the out-

put data rate to one-half the sample clock rate. Data is

output in two’s complement format. The MAX107 oper-

ates from a +5V analog supply and the LVDS output

ports operate at +3.3V. The data converter’s typical

power dissipation is 2.6W. The device is packaged in

an 80-pin, TQFP package with exposed paddle, and is

specified for the extended (-40°C to +85°C) tempera-

ture range. For a higher-speed, 800Msps version of the

MAX107, please refer to the MAX105 data sheet.
