MAXIM MAX1213 User Manual
General Description
The MAX1213 is a monolithic, 12-bit, 170Msps analogto-digital converter (ADC) optimized for outstanding
dynamic performance at high-IF frequencies up to
300MHz. The product operates with conversion rates
up to 170Msps while consuming only 788mW.
At 170Msps and an input frequency up to 250MHz, the
MAX1213 achieves a spurious-free dynamic range
(SFDR) of 72.9dBc. Its excellent signal-to-noise ratio
(SNR) of 65.8dB at 10MHz remains flat (within 2dB) for
input tones up to 250MHz. This ADC yields an excellent
low-noise floor of -68dBFS, which makes it ideal for
wideband applications such as cable head-end
receivers and power-amplifier predistortion in cellular
base-station transceivers.
The MAX1213 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 MAX1213 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.
