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 10
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.
