Overview

The Creonic Wideband Digital Down Converter (DDC) digitally converts the input signal at IF frequency down to baseband by multiplying input samples with sine/cosine waves generated by numerical controlled oscillators (NCO). Down converted samples are then decimated by a factor ranging from 2 to 2048 with multiplying step of 2. A CIC and 4 stages of half band filters are integrated within the decimator. The core accepts a real signal at input and provides complex I/Q baseband data at the output. The parallel architecture of the core allows for an input throughput up to 2.4 Gsps, data symbol rate up to 540 Msymb/s, making it a perfect fit for ultra high throughput applications such as wideband DVB-S2X communication.

Features

    Device Utilization and Performance

    High input throughput of up to 2.4 Gsps Supported signal bandwidth of up to 600 MHz Tunable IF frequency from 10 to 700 MHz with a precision of at least 2 Hz Spurious-free dynamic range (SFDR) of at least 83 dB, filter’s passband ripple less than 0.05 dB
