Taiwan-based MediaTek announces 800G MACsec PHY

MediaTek announced its MT3729 800G (400G dual port) MACsec retimer PHY for data centers and cloud infrastructure.

The new device, which integrates MediaTek’s 56G PAM4 SerDes technology, is available as a standalone application-specific standard part (ASSP) or it can be integrated into a network controller chip.  The MT3729 800G PHY is ideal for line cards or switch fabrics in conjunction with network controller application-specific integrated circuits (ASICs) to build multi-terabit network servers, switches and routers. It enables secure data links and highly accurate precision time protocol (PTP) timestamping.

“With our broad portfolio of networking solutions, MediaTek is meeting the growing bandwidth and security needs of modern network infrastructure, including hyper-scale, cloud, service provider and enterprise networks,” said Jerry Yu, MediaTek Corporate Vice President. “Our MT3729 PHY integrates advanced MACsec-based encryption for secure communications and highly accurate PTP timestamping for the latest 5G synchronization requirements, while also giving our customers different integration options for added flexibility.”

The MT3729 packs four different operation modes:

  • Retimer Mode: Built-in signal enforcement technology extends the SerDes connection distance and transmission to the edge for more precise timestamping. 
  • Forward/Reverse Gearbox Mode: Support for bitrate translation between 56G and 28G links enables next generation switches to seamlessly connect with existing infrastructure.
  • MUX/DeMUX Mode: Hitless MUX and broadcast switching meets networking redundancy requirements. 
  • MACsec Mode: IEEE 802.1AE MACsec support enables secure communications with AES-128 and AES-256 encryption from 1G to 400G per port.

The MT3729 PHY supports up to 16 bi-directional links at 56G PAM4, up to 28G NRZ SerDes and 1G SGMII. To meet the stringent 5G infrastructure timing requirements, the MT3729 supports IEEE 1588v2 and SyncE up to Class-C for greater accuracy and more flexibility with timestamping formats.

Ericsson and Mediatek test 5G Voice over New Radio (VoNR)

Ericsson has collaborated with MediaTek on performing interoperability tests spanning Stand Alone New Radio (SA NR), 5G Core and IP Multimedia Subsystem (IMS) to ensure that voice support is enabled as service providers evolve their 4G networks to 5G. The two partners have also successfully tested Evolved Packet System (EPS) Fallback for situations where SA is not available.

The interoperability test, which was conducted at the Ericsson Lab in Kista in early December, involved the use of an end-to-end solution from Ericsson and Dimensity 1000 commercial chipset from MediaTek deployed on a 3.5GHz TDD band.

With Standalone New Radio (SA NR), a 5G-enabled device does not need to rely on 4G technology to make 5G voice (VoNR) calls. With the arrival of standalone NR access, voice and other communication services will need to be provided, requiring the 5G network to support native voice calling services for 5G smartphones. Using VoNR on SA architecture, service providers will be able to offer voice services on 5G-voice-capable devices as well as enhanced mobile broadband (eMBB) services to consumers and business users.

Hannes Ekström, Head of Product Line 5G RAN, Ericsson, says: “Although 5G is closely associated with superior data-transfer capabilities, voice services remain essential for mobile users. So 5G phones are expected to provide all the capabilities of 4G phones in addition to new 5G features and services. Ensuring continued voice services on 5G devices must therefore be addressed properly.

Mediatek Unveils Ultra Power-Saving Mobile Processor

MediaTek introduced an "ultra power-saving" mobile processor for the next generation of smartphones.

The MediaTek Helio P20, which promises 25 percent better power efficiency than its predecessor, leverages 16nm process technology and is the world’s first SoC to support low power double data rate random access memory – LPDDR4X.  The processor features upgraded CPU and GPU capabilities with its True Octa-Core architecture clocked up to 2.3GHz, taking full advantage of ARM Cortex A53 cores. A new Mali T880 graphics unit is clocked at 900MHz.

The MediaTek Helio P20 integrates an LTE Cat.6 modem with 2x20 carrier aggregation for 300/50Mbps top data speeds. The SoC supports global Dual-SIM Dual Standby. For regions where GSM is no longer available, the SoC will have simultaneous standby on WCDMA network. Additionally, MediaTek Helio P20 supports LTE multimedia broadcast and multicast service. This allows mobile devices to receive HD video content over LTE.

For improved processing power and optimum battery performance, MediaTek Helio P20 integrates LPDDR4X, providing 70 percent more bandwidth than the LPDDR3 and 50 percent power savings by lowering supply voltage to 0.6v, resulting in a quicker, smoother user experience for camera, video and gaming apps.

“MediaTek designed the MediaTek Helio P20 to meet today’s consumer demand for sleek, powerful yet highly power efficient mobile devices,” said Jeffrey Ju, Executive Vice President and Co-Chief Operating Officer at MediaTek.

DOCOMO Partners with Mediatek on 5G Access

NTT DOCOMO is working with MediaTek of Taiwan to jointly develop and conduct trials of technology that will enable increased data capacity for 5G systems.

The trials, which will be conducted in either Taiwan or Japan from 2017 onwards, will develop a communication system to combine non-orthogonal multiple access (NOMA) wireless access technologies from DOCOMO and multi-user interference cancellation (MUIC) technologies from MediaTek. NOMA multiplexes signals at a base-station transmitter to leverage the increased signal processing capacity of a user device to cancel interference among multiplexed user signals. MUIC utilizes receiver antennas to remove interference from other users and increase capacity when a base station transmits a signal to a number of users at the same time.

The two companies will also study a new 5G Radio Access Technology and chipsets required for 5G devices, with joint trials to be carried out from 2018 onwards.

"DOCOMO is excited to work with MediaTek, an innovator with expertise in the technical requirements of 5G," said Seizo Onoe, Executive Vice President and Chief Technology Officer at DOCOMO. "The potential opportunities for 5G to enable people to connect with devices are endless. We're eager to see our 5G network inspire innovative inventions to benefit technology, life and business."
