General Description

Comcores Digital Up-Converter (DUC) and Digital Down Converter (DDC) IP platform core is a silicon agnostic implementation of a key component for digital radio front-end targeting any ASIC, FPGA or ASSP technologies. The flexible digital processing architecture enables multi-standard and multi-carrier operations handling LTE, LTE-A, and WCDMA in compliance with 3GPP standard.

The core performs up- and down conversion of multiple streams of receivers and transmitters signals with powerful interface options and management capabilities. It can dynamically be configured to handle up to 8 transmit paths and 8 receive paths each running with up to 8 carriers having a total aggregated bandwidth of up to 200 MHz.

It interfaces on one side to DAC's and ADC's and on the other side to one or several CPRI-links toward the base station.
