DTA-2125

25G SmartNIC Optimized for SMPTE 2110

Ideal for software-based SMPTE 2110 applications, the DTA-2125 supports up to two uncompressed UHD streams or ten full-HD streams (5 Rx + 5 Tx).

Functions as a standard NIC for Linux and Windows, with built-in PTP synchronization and dedicated hardware pipes optimized for SMPTE 2110 performance.

Features

Acts as a standard 25G NIC, with hardware acceleration to reduce CPU load for AV-over-IP streaming on Linux and Windows.

Ten dedicated hardware pipes (5 Rx, 5 Tx) for low-latency transport of uncompressed video.

AvFifo API for easy creation of SMPTE 2110 and 2022-6 software applications.

SFP28 slot supporting both 25G and 10G optical or electrical modules.

Applications

Ideal for creating SMPTE 2110 solutions entirely in software, while meeting all timing requirements. Common use cases include:

Software encoders, decoders, transcoders

Playout systems

Live production mixers

Monitoring and multiviewer setups

Recording and compliance solutions

Custom AV-over-IP applications tailored to your needs

Block Diagram

Outlined below is the block diagram of the DTA-2125's firmware, organized into two pathways: transmission (upper section) and reception (lower section).

The transmission path incorporate three hardware pipes that directly interface with the user application, resulting in excellent performance. Packets from these hardware pipes are multiplexed with those from the software pipes and the standard network stack. A scheduler ensures that each packet is transmitted precisely according to its PTP timestamp.

Conversely, the receive path also integrates 5 hardware pipes directly interfaced with the user application. All remaining packets are dispatched to a software router. This router channels real-time AV streams to the software pipes, while normal standard network traffic is forwarded to the conventional network stack.
