General Description
The MAX1124 is a monolithic 10-bit, 250Msps analog-
to-digital converter (ADC) optimized for outstanding
dynamic performance at high IF frequencies up to
500MHz. The product operates with conversion rates of
up to 250Msps while consuming only 477mW.
At 250Msps and an input frequency of 100MHz, the
MAX1124 achieves a spurious-free dynamic range
(SFDR) of 71dBc. Its excellent signal-to-noise ratio
(SNR) of 57.1dB at 10MHz remains flat (within 1dB) for
input tones up to 500MHz. This makes the MAX1124
ideal for wideband applications such as digital predis-
tortion in cellular base-station transceiver systems.
The MAX1124 requires a single 1.8V supply. The ana-
log 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 fre-
quencies as high as 500MHz. This helps to reduce the
phase noise of the input clock source. A differential
LVDS sampling clock is recommended for best perfor-
mance. The converter’s digital outputs are LVDS com-
patible, and the data format can be selected to be
either two’s complement or offset binary.
The MAX1124 is available in a 68-pin QFN with
exposed paddle (EP) and is specified over the industri-
al (-40°C to +85°C) temperature range.
For pin-compatible, lower speed versions of the
MAX1124, refer to the MAX1122 (170Msps) and the
MAX1123 (210Msps) data sheets. For a pin-compatible
8-bit version of the MAX1124, refer to the MAX1121
data sheet.
