MCP37211-200 AND MCP37D11-200
Description
The MCP37211-200 is Microchip's baseline 12-bit
200 Msps pipelined ADC, featuring built-in high-order
digital decimation filters, noise-shaping requantizer,
gain and offset adjustment per channel and fractional
delay recovery.
The MCP37D11-200 device features digital down-
conversion and CW beamforming capability, in addition
to the features offered by the MCP37211-200.
All devices feature harmonic distortion correction and
DAC noise cancellation that enable high-performance
specifications with SNR of 71.3 dBFS (typical) and
SFDR of 90 dBc (typical).
These A/D converters exhibit industry-leading low-
power performance with only 468 mW operation while
using the LVDS interface at 200 Msps. This superior
low-power operation coupled with high dynamic
performance makes these devices ideal for various
high-performance, high-speed data acquisition
systems, including communications equipment, radar
and portable instrumentation.
In single or dual-channel mode, the Noise-Shaping
Requantizer (NSR) feature can allow the ADC to
improve SNR beyond a conventional 11- or 12-bit ADC.
The NSR reshapes the quantization noise, such that
most of the noise power is pushed outside the
frequency of interest. As a result, SNR is improved
significantly within a selected frequency band of
interest while SFDR is not affected.
The digital down-conversion option in the MCP37D10-
200 can be utilized with the decimation and quadrature
output (I and Q data) option, and offers great flexibility
in various digital communication system designs,
including cellular base-stations and narrow-band
communication systems.
The output decimation filter option improves SNR
performance up to 73.7 dBFS. The digital down-
conversion option, in conjunction with the decimation
and quadrature output options, offers great flexibility in
digital communication system design, including cellular
base-stations and narrow-band communications.
These devices can have up to eight differential input
channels through an input MUX. The sampling rate is
up to 200 Msps when a single channel is used, or
25 Msps per channel when all eight input channels are
used.
In dual or octal-channel mode, the Fractional Delay
Recovery (FDR) feature digitally corrects the difference
in sampling instance between different channels, so
that all inputs appear to have been sampled at the
same time.
AutoSync mode offers a great design flexibility when
multiple devices are used in applications. It allows
multiple devices to sample input synchronously at the
same clock.
The differential full-scale analog input range is
programmable up to 2.975 V
P-P
. The ADC output data
can be coded in two's complement or offset binary
representation, with or without the data randomizer
option. The output data is available as full-rate CMOS
or Double-Data-Rate (DDR) LVDS.
These devices also include various features designed
to maximize flexibility in the user’s applications and
minimize system cost, such as a programmable PLL
clock, output data rate control and phase alignment
and programmable digital pattern generation. The
device’s operational modes and feature sets are
configured by setting up the user-programmable
registers.
The device is available in Pb-free TFBGA-121 and
VTLA-124 packages. The device with a TFBGA-121
package is AEC-Q100 qualified for automotive
applications and operates over the extended
temperature range of -40°C to +125°C.
