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.
The parallel architecture of the core allows for an input throughput of up to 2.4 Gsps and 600 MHz signal bandwidth, making it a perfect fit for ultra high throughput applications such as wideband DVB-S2X communication.
Applications
Wideband satellite communication
Wideband wireless backhaul
Wideband cable modems
Electronic surveillance applications
