Integrated license key accesses ADX4 algorithm to boost ADC performance
The EV12AQ600/605-ADX4 multi-core ADC features an integrated ADX4 license key enabling enhanced dynamics when operating at up to a peak of 6.4Gsamples per second (single channel mode), said Teledyne SP Devices.
The ADX4 post-processing algorithm is compatible with Xilinx Kintex Ultrascale FPGAs and delivers up to 10dBFS of SFDR dynamic spurs reduction and close to one effective bit extra resolution in broadband applications.
The ADX4 spur reduction IP dynamically attenuates spurious frequency components resulting from gain, offset and phase mismatches between the four ADC cores. For the EV12AQ600 and EV12AQ605, time-interleaving four cores quadruples the sample rate from 1.6 to 6.4Gsamples per second. The mismatch errors between the ADC cores reduce spurious free performance, confirmed Teledyne. ADX4 delivers a spurious free dynamic range (SFDR) boost of up to 10dB. That boost is particularly noticeable in broadband applications, and as it requires no hardware design changes is available on demand. The ADX4 code module is programmed into the post-processing FPGA and retrofitted in the field if required.
Unlike a single or multi-point calibration, ADX4 digital error correction can deliver spur suppression even when the errors vary over frequency, said Teledyne. The unwanted aliasing spurs are suppressed into the noise floor.
Customers can transition their orders across to the -ADX4 options of their EV12AQ600 / EV12AQ605 devices and add the ADX4 module to the Xilinx FPGA code load.
