General Description
The MAX19542 monolithic 12-bit, 170Msps analog-to-
digital converter (ADC) is optimized for outstanding
dynamic performance at high-IF frequencies of
300MHz and beyond. This device operates with con-
version rates up to 170Msps while consuming only
907mW.
At 170Msps and an input frequency of 240MHz, the
MAX19542 achieves a spurious-free dynamic range
(SFDR) of 76.4dBc. The MAX19542 features an excel-
lent signal-to-noise ratio (SNR) of 65dB at 10MHz that
remains flat (within 3dB) for input tones up to 250MHz.
This makes the MAX19542 ideal for wideband applica-
tions such as power-amplifier predistortion in cellular
base-station transceiver systems.
The MAX19542 operates in either parallel mode where
the data outputs appear on a single parallel port at the
sampling rate, or in demux parallel mode, where the out-
puts appear on two separate parallel ports at one-half
the sampling rate. See the Mode of Operation section.
The MAX19542 operates on a single 1.8V supply. The
analog input is differential and can be AC- or DC-cou-
pled. The ADC also features a selectable on-chip
divide-by-2 clock circuit that allows clock frequencies
as high as 340MHz. This helps to reduce the phase
noise of the input clock source, allowing for higher
dynamic performance. For best performance, a differ-
ential LVPECL sampling clock is recommended. The
digital outputs are CMOS compatible and the data for-
mat can be selected to be either two’s complement or
offset binary.
A pin-compatible, 12-bit, 125Msps version of the
MAX19542 is also available. Refer to the MAX19541
data sheet for more information.
The MAX19542 is available in a 68-pin QFN with
exposed paddle (EP) and is specified over the extend-
ed (-40°C to +85°C) temperature range.
