Signal generation capabilities added to our latest product
In this issue we are pleased to announce the release of our latest
digitizer product - SDR14 - which features both ADCs and DACs with 14
bits vertical resolution.
SDR14 - Ideal for Software Defined Radio Applications!
The SDR14 is a high-speed digitizer in the ADQ V6 Digitizer family with
two analog inputs and two analog outputs, making it ideal for software
defined radio applications. The unique combination of dynamic range and
sampling frequency is enabled by SP Devices' ADX IP-core – a mismatch
error correction technology for time-interleaved ADCs.
The SDR14 offers a remarkable 800 MSPS per channel, 14-bit digitization
with two single-ended analog inputs that are AC-coupled with a 50 Ohm
input impedance. This makes the dual-input SDR14 the ideal platform for IF
sampling radio front-ends as well as image reject mixers or dual receiver
systems. At the output side, each channel can reconstruct at 1600 MSPS
with 14-bit resolution, and the analog outputs can be configured either as
DC or AC-coupled with 50 Ohms single-ended output impedance.
The dual DC-coupled device is suitable for Zero-IF transmitters while the
AC-coupled output is optimized for IF signal generation. The SDR14
supports waveform recording and arbitrary waveform generation as well as
real-time data streaming. The FPGA is an open architecture providing an
easy access embedded real-time signal processing.
SP Devices' Value Proposition for the Test & Measurement Markets
In test and measurement (T&M) systems performance and signal fidelity is
key and achieving high performance often require the use of very expensive
custom components. By using signal processing technology from SP Devices,
performance degrading artifacts originating from the analog domain is
compensated for in the digital domain and as a result our customers can
stay ahead of competition and achieve state-of-the-art performance based
on commercial off-the-shelf (COTS) components.
SP Devices' proprietary ADX interleaving IP enables unprecedented sampling
rates and high effective bandwidth with no loss of dynamic range while the
ADL linearization IP improves the linearity of the analog input path and
therefore increase the dynamic range and the total performance of the T&M
system. In summary, the use of ADX and ADL IP from SP Devices will provide
the performance needed for these advanced T&M systems while allowing for
the use of COTS components.
About SP Devices' ADX Interleaving Technology
Time-interleaving of analog-to-digital converters (ADCs) is a way to
increase the overall system sampling rate by using several ADCs in
parallel. The challenge is to handle the mismatch between the individual
ADCs, especially at higher frequencies. With its unique self-learning and
high-resolution capabilities, SP Devices' ADX technology offers previously
unseen performance. Corrections are made transparently and in real-time
without any need for calibration signals or idle time slots during which
to perform calibration. The mismatch correction algorithm supports a
resolution of up to 16 bits, with a preserved SFDR of up to 95 dB,
depending on the properties of the specific ADC array.
SP Devices Provides Solutions to the Complete Value Chain
We help our customers to improve competitiveness regardless of where they
are positioned in the value chain. The offering from SP Devices covers the
complete range from Silicon Manufacturers to System Integrators. SP Devices'
products are available as Silicon IP, FPGA IP, reference designs, and
complete digitizer boards.
The ADX interleaving technology is available as silicon IP for chip
manufacturers and semiconductor companies who need to increase ADC
sampling speed. ADX is also available as FPGA IP, targeting the market of
system suppliers, digitizer companies, and T&M companies.
For customers who do not want to design their own digitizer solution, SP
Devices offers both off-the-shelf digitizer solutions as well as
customized digitizers.
