Xilinx is creating an environment where employees, customers, and
partners feel welcome and included. To that end, we’re removing non-
inclusive language from our products and related collateral. We’ve
launched an internal initiative to remove language that could exclude
people or reinforce historical biases, including terms embedded in our
software and IPs. You may still find examples of non-inclusive
language in our older products as we work to make these changes and
align with evolving industry standards. Follow this link for more
information.

targeted applicaons:
• 5G NR physical layer funconal ooad, including but not limited to:
○Low-density parity check (LDPC) encoding and decoding
○Rate matching and dematching
○Code block (CB) and CB group (CBG) processing with HARQ buer management logic in
lookaside mode
• 4G LTE physical layer funconal ooad, including but not limited to:

○CB processing with HARQ buer management in lookaside mode
Note: The Zynq UltraScale+ RFSoC ZU48DR device also supports concurrent 4G LTE/5G NR L1 ooad,
assuming that the necessary hardware resources are available.
The T2 card value proposion is in ooading CPU intensive encode and decode computaons
involving LDPC operaons, thereby reducing costly CPU resources. The Zynq UltraScale+ RFSoC
has hard IP blocks for SD-FEC (eight SD-FEC cores per device) which can be congured to run
LDPC encode and decode operaons.

Chapter 2
Features
The main features of the T2 card are as follows:
•Card over-stress protecon: The T2 card has a card protecon circuit that iniates a fatal
shutdown if either temperature or power consumpon thresholds are crossed.
Before this threshold is reached, however, the SC signals to the Zynq UltraScale+ RFSoC to
reduce the 5G workload power immediately. This indicaon is accomplished using the
RF_CPU_RST and RF_RST_REQ handshake signals.
The precise threshold levels have been determined through tesng and factory sengs to
ensure card safety. They cannot be changed.
•Out-of-band telemetry: Telemetry data for the card is provided to the server board
management controller (BMC) over the PCIe SM bus from the T2 SC. The PLDM over MCTP
protocol is used for this communicaon between server BMC and T2 SC, and implements a
thermal closed loop control mechanism for card cooling.
All required telemetry data, including board temperatures and power consumpon, is
available.
•In-band telemetry: Telemetry data for the card is also available in-band over PCIe. The
following telemetry data is available:
• Zynq UltraScale+ RFSoC
• Board inlet temperature
• Board outlet temperature
• DDR4 vicinity temperature
• PCIe 12V current
• In-band SC rmware update
Note: The PCIe 3.3V current is characterized (2.6A) but not measured.
•In-band FPGA ash update: Updang the user ash image in-band over PCIe is supported
using the flash_app ulity provided in the host soware installaon. Details are found
within the T2 Telco Accelerator Card Installaon Guide (UG1527).
Some design components must be designed into the Zynq UltraScale+ RFSoC PL and PS to
support this funcon.

Chapter 3
Pin Mapping
This chapter presents the pin mapping for the ZU48DR Zynq® UltraScale+™ RFSoC on the T2
card.
PCIe Interface
The PCIe® interface on the T2 card has 16 lanes and can operate in Gen 3 x16 mode or Gen 4
x8x8 bifurcated mode.
Using the PCIe Interface
• The PCIe interface is supported with a dedicated IP block that must be instanated in the
design.
• PCIe lane reversal is in use.
• The server slot used with the T2 card must be a x16 capable and congured correctly for card
detecon and use. The Gen 4 x8x8 mode of operaon requires x8 bifurcaon to be enabled,
whereas Gen 3 x16 requires x16 mode.
