General Description
The MAX1213N is a monolithic, 12-bit, 170Msps analog-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 applications such as communications receivers, cable-head
end receivers, and power-amplifier predistortion in cellular base-station transceivers.
The MAX1213N operates from a single 1.8V power supply. The analog input is designed for AC-coupled differential 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 lowvoltage differential signal (LVDS) sampling clock is
recommended for best performance. The converter provides 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.
