1.8V, Low-Power, 12-Bit, 170Msps
ADC for Broadband Applications
General Description
Features
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.
♦ 170Msps Conversion Rate
♦ Excellent Low-Noise Characteristics
SNR = 67.2dB at f = 100MHz
IN
SNR = 65.2dB at f = 250MHz

♦ Excellent Dynamic Range
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.
SFDR = 87dBc at f = 100MHz

♦ Internal 1.24V-Bandgap Reference
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.
♦ On-Chip Selectable Divide-by-2 Clock Input
♦ LVDS Digital Outputs with Data Clock Output
♦ MAX1213NEVKIT Available
Ordering Information
