The MAX1214 is a monolithic, 12-bit, 210Msps analog-to-digital converter (ADC) optimized for outstanding
dynamic performance at high-IF frequencies up to
300MHz. The product operates with conversion rates
up to 210Msps while consuming only 820mW.
At 210Msps and an input frequency up to 250MHz, the
MAX1214 achieves a spurious-free dynamic range
(SFDR) of 77.2dBc. Its excellent signal-to-noise ratio
(SNR) of 66dB at 10MHz remains flat (within 2dB) for
input tones up to 300MHz. This ADC yields an excellent
low noise floor of -67.6dBFS, which makes it ideal for
wideband applications such as cable-head end
receivers and power-amplifier predistortion in cellular
base-station transceivers.
The MAX1214 requires a single 1.8V supply. The analog
input is designed for either differential or single-ended
operation and can be AC- or DC-coupled. The ADC also
features a selectable on-chip divide-by-2 clock circuit,
which allows the user to apply clock frequencies as high
as 340MHz. This helps to reduce the phase noise of the
input clock source. A low-voltage differential signal
(LVDS) sampling clock is recommended for best performance.
The converter's digital outputs are LVDS compatible
and the data format can be selected to be either
two's complement or offset binary.
The MAX1214 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.
