1.8V, Dual, 12-Bit, 210Msps ADC for
Broadband Applications
General Description
The MAX1219 dual, monolithic, 12-bit, 210Msps analog-
to-digital converter (ADC) provides outstanding dynam-
ic performance up to a 250MHz input frequency. The
device operates with conversion rates up to 210Msps
while consuming only 800mW per channel.
At 210Msps and an input frequency of 200MHz, the
MAX1219 achieves a 79dBc spurious-free dynamic
range (SFDR) with excellent 65.5dB signal-to-noise ratio
(SNR) at 200MHz. The SNR remains flat (within 3dB) for
input tones up to 250MHz. This makes the MAX1219
ideal for wideband applications such as communications
receivers, cable head-end receivers, and power-amplifi-
er predistortion in cellular base-station transceivers.
The MAX1219 operates from a single 1.8V power sup-
ply. The analog inputs of each channel are 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
420MHz and reduces 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 MAX1219 is available in a 100-pin TQFP package
with exposed paddle and is specified over the extend-
ed (-40°C to +85°C) temperature range. Refer to the
MAX1218 (170Msps) and the MAX1217 (125Msps)
data sheets for lower speed, pin-compatible devices.
