DUC/DDC

General Description

Comcores Digital Up Converter (DUC) and Digital Down Converter (DDC) IP core is a silicon agnostic implementation of a key building block in radio front-end design targeting any ASIC, FPGA or ASSP technologies. The flexible digital processing architecture enables multi-standard and multi-carrier operations handling LTE, LTE-A, WCDMA and NR in compliance with 3G, 4G and 5G standards.

The core performs up-and down-conversion of multiple streams of receivers and transmitters signals. It can dynamically be configured to handle up to 8 transmit paths and 8 receive paths. A total of 8 component carriers per path is supported up to a total aggregated BW of 200 MHz running at a 491,52 MHz clock-rate.

It interfaces on one side to DAC’s and ADC’s and on the other side to one or several CPRI, eCPRI, RoE or xRAN subsystems toward the base station using a standard streaming interface.
