Qualcomm has long relied on third-party 5G and 10G Ethernet chips to enable high-speed network port functionality on its router platforms. However, with advancements in technology, Qualcomm has officially launched its own 5G and 10G Ethernet chips, adding a crucial piece to its product lineup and further enhancing overall performance and integration.
Overview of the new model and its features
The Ethernet chips launched by Qualcomm this time include the following models:
- 5G Chips**: QCA8101, QCA8102
- 10G Chip**: QCA8111, QCA8112
The main difference between these chips lies in whether they support MACsec (Media Access Control Security). Among them, the QCA8102 and QCA8112 support MACsec technology, while the QCA8101 and QCA8111 do not have this feature.
Main Technical Features and Advantages
Qualcomm's QCA8101/QCA8102/QCA8111/QCA8112 series chips integrate multiple advanced technologies, aiming to deliver high-performance, low-power network solutions:
1. Green ETHOS® Energy-Saving Technology
This technology can significantly reduce power consumption when the chip is either actively operating or in idle mode, and it supports ultra-low power modes, such as when the network cable is unplugged or the port is in a shutdown mode.
2. Supports multiple Ethernet standards
The QCA8101/QCA8102/QCA8111/QCA8112 support IEEE 802.3az Energy Efficient Ethernet (EEE), applicable to 100BASE-TX, 1000BASE-T, 2500BASE-T, and 5000BASE-T.
The QCA8111/QCA8112 further supports 10G Ethernet (10000BASE-T) to meet higher bandwidth demands.
3. Wake-on-LAN (WoL) feature
The chip supports WoL technology, effectively managing the system's overall power consumption and improving energy efficiency.
4. Time Synchronization Technology
Supports IEEE 1588 v2.1 and Synchronous Ethernet (SyncE), providing a comprehensive time synchronization solution.
The chip can perform master-slave clock synchronization through PTP (Precision Time Protocol) packets and supports both first-order and second-order clock modes.
Synchronous Ethernet technology can recover clock output from the data received through network cables, ensuring high-precision time synchronization.
5. Cable Diagnostics Test (CDT) technology
The chip features built-in cable diagnostic technology, capable of measuring cable length, detecting cable conditions, and identifying remote or local PHY faults, as well as poor or marginal network cables and connectors.
6. MACsec security technology **(only available for QCA8102 and QCA8112)**
Supports the IEEE 802.1AE standard, providing hop-by-hop link layer security with symmetric key AES-GCM encryption and authentication.
Complete built-in processing functionality enables efficient data path security without the need for software intervention.
Usage scenarios and integration advantages
These chips can be paired with Qualcomm's IPQ9574, IPQ5332, and IPQ5422 platforms, connecting via USXGMII (Universal Serial 10 Gigabit Media Independent Interface) to easily achieve high-speed network port functionality. Since there is no longer a need to port third-party drivers, the integration process is greatly simplified, allowing developers to design high-performance network devices more efficiently and quickly.
Qualcomm's technological breakthrough
Qualcomm's newly launched 5G and 10G Single Port Transceiver not only completes the technical puzzle of its own chips but also eliminates reliance on third-party drivers, providing a more flexible and efficient solution for achieving high-speed network interfaces. This technological breakthrough will help Qualcomm further solidify its leadership position in the network equipment market.
