1.8V, Low-Power, 12-Bit, 210Msps
ADC for Broadband Applications
General Description
The MAX1214N is a monolithic, 12-bit, 210Msps 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 210Msps while consuming only 799mW.
At 210Msps and an input frequency up to 100MHz, the
MAX1214N achieves an 81.3dBc spurious-free dynam-
ic range (SFDR) with excellent 67dB 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.
The MAX1214N 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 420MHz. A low-
voltage differential signal (LVDS) sampling clock is rec-
ommended for best performance. The converter
provides LVDS-compatible digital outputs with data for-
mat selectable to be either two’s complement or offset
binary.
The MAX1214N 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.
