XCZU21DR-2FFVD1156I

The Xilinx XCZU21DR-2FFVD1156I is a member of the Zynq UltraScale+ RFSoC family, designed for multiband, multi-mode cellular radios and cable infrastructure. This SoC platform features a robust processing system with a quad-core Arm Cortex-A53 and a dual-core Arm Cortex-R5.

Integrated with UltraScale architecture programmable logic, the device includes RF-ADCs, RF-DACs, and soft-decision FECs. This combination enables the implementation of complete software-defined radios, supporting direct RF sampling data converters and enabling CPRI and gigabit Ethernet-to-RF on a single, highly programmable SoC. The XCZU21DR-2FFVD1156I boasts 930300 cells and is built on 16nm technology with a 0.9V operating voltage.

The RF data converter subsystem contains multiple radio frequency analog-to-digital converters (RF-ADCs) and radio frequency digital-to-analog converters (RF-DACs). These high-precision, high-speed, power-efficient converters can be configured individually or in pairs for I/Q data. Additionally, soft-decision Forward Error Correction (SD-FEC) blocks are included for error control in data transmission, supporting LDPC decode/encode and Turbo decode for applications like 5G wireless and DOCSIS.

The processing system includes peripherals for interfacing with external memories, such as a multi-protocol dynamic memory controller, DMA controller, NAND controller, SD/eMMC controller, and Quad SPI controller.
