Analog Devices debuts Single-pair Power over Ethernet at 1 km

Analog Devices introduced the first Single-pair Power over Ethernet (SPoE) Power Sourcing Equipment (PSE) and Power Device (PD) chipsets.

Potential SPoE applications include smart buildings, factory automation, and other applications at the edge of traditional networks. 

Analog Devices’ new SPoE solutions, LTC4296-1 and LTC9111, reduce reliance on localized power and batteries by using a single twisted pair of Ethernet cables to provide efficient, reliable, easily installed power at reduced size and weight. The company says the solution an reliably transfer both power and data over one kilometer in industrial Ethernet applications.

Analog Devices’ new LTC4296-1 5-port SPoE PSE with Classification and LTC9111 SPoE PD with Polarity Correction products support both SPoE and Power over Data Line (PoDL) variants of single-pair powering. SPoE augments Single Pair Ethernet (SPE) to provide more reliable, fault-tolerant, and interoperable point-to-point power solutions, delivering up to 52W. Both products are 802.3cg compliant and support Serial Communication Classification Protocol (SCCP).

“The Intelligent Edge is one of the most exciting developments of the digital era as computing power is pushed to previously inaccessible applications and locations,” said Leo McHugh, Vice President of Industrial Automation at Analog Devices. “Analog Devices is committed to delivering the unrivaled technology and solutions our customers need to leverage the full potential of the Intelligent Edge in smart buildings and factories as well as many more applications in the future.”

Analog Devices intros RadioVerse chip for 5G RUs

Analog Devices introduced its RadioVerse System-on-Chip (SoC) series for energy efficient 5G RUs.

The ADRV9040 is the first in the new RadioVerse SoC series. It offers eight transmit and receive channels of 400MHz bandwidth and integrates advanced digital signal processing functions, including carrier digital up-converters (CDUC), carrier digital down-converters (CDDC), crest factor reduction (CFR) and digital pre-distortion (DPD). This expanded signal processing can eliminate the need for a field-programmable gate array (FPGA), thereby reducing thermal footprint, and total system size, weight, power, and cost. The SoC’s DPD algorithms were developed using advanced machine learning techniques and are optimized in close collaboration with major power amplifier (PA) vendors to ease the design burden and deliver best-in-class wide bandwidth performance. The algorithms are fully tested and validated across 4G and 5G use cases, including various PA technology types such as gallium nitride (GaN). In addition, the ZiF radio architecture simplifies RF filtering and signal chain components, reducing RU cost and development time for band and power variants designs.

ADI said its new SoC series provides advanced RF signal processing with expanded digital functionality and RF capacity that greatly improves 5G RU performance and energy efficiency. 

“Samsung and ADI have long worked together to support the swift deployment of 5G in the global market,” said Dong Geun Lee, Vice President and Head of Hardware R&D Group, Network Business at Samsung Electronics. “We are excited for the successful launch of ADI’s new SoC, as we expect this cutting-edge technology will bring better 5G experience to consumers. We look forward to expanding our engagement with ADI.”

“RadioVerse SoCs are designed to optimize the full radio solution rather than just a single component or interface,” said Joe Barry, Vice President of Wireless Communications at Analog Devices. “Each successive generation has provided expanded capabilities, bandwidth and performance, while improving overall RU efficiency. This new RadioVerse SoC series takes a big step forward by delivering multiple advancements in signal processing to meet the demanding needs of 5G.”

Analog Devices unveils 28 nm DA converter for 4G/5G

Analog Devices has introduced a 28 nm D/A converter as part of a new series of high speed digital-to-analogue converters, designed to address the requirements of gigahertz bandwidth applications and provide the spectral efficiency needed for 4G/5G multi-band base stations and 2 GHz E-band microwave point-to-point backhaul platforms.

Based on 28 nm CMOS technology, the new AD9172 device is claimed to set performance benchmarks in terms of dynamic range, signal bandwidth and low power consumption.

Analog Devices' dual 16-bit AD9172 product supports 12 GSPS and provides direct-to-RF synthesis up to 6 GHz, eliminating the IF-to-RF up-conversion stage and LO generation to simplify the overall RF signal chain and reducing system cost. The device is designed to maintain superior linearity and noise performance across the RF frequencies to allow a high level of configurability.

In addition, independent numerically controlled oscillator (NCO), digital gain control and a range of interpolation filter combinations per input channel provide a suite of signal processing options to allow flexible signal chain partitioning between the analogue and digital domains, enabling the development of software defined platforms. The AD9172 is complemented by the AD9208 28 nm analogue-to-digital converter.

Key features of Analog Devices' new AD9172 device, which is offered in a 10 x 10 mm 144-ball BGA-ED package, include:

1.         Support for single- and multi-band wireless applications with 3 bypassable complex data input channels per RF DAC at a maximum complex input data rate of 1.5 GSPS with independent NCO per input channel.

2.         Selectable interpolation filters enabling up to 8x configurable data channel interpolation and up to 12x configurable final interpolation to support a full set of input data rates.

3.         Final 48-bit NCO that operates at the DAC rate to support frequency synthesis up to 6 GHz.

4.         Flexible 8-lane 15 Gbit/s JESD204B (subclass 0 and 1) interface that supports 12-bit high density mode for enhanced data throughput.

5.         Low noise on-chip PLL clock multiplier that supports 12 GSPS DAC update rate and provides observation ADC clock driver with selectable divide ratios.

In conjunction with the AD9172, Analog Devices also introduced its dual 14-bit AD9208 product optimised to deliver wide input bandwidth, high sample rate, excellent linearity and low power in a small package. With sampling speeds up to 3.0 GSPS, the A/D converter is designed to facilitate direct RF signal processing architectures and enable high oversampling.

The device's full power bandwidth supports IF signal sampling up to 9 GHz (-3 dB point), with up to 96-tap programmable finite impulse response (FIR) filter block that can be configured for channel equalisation and/or quadrature error correction. In addition, four integrated wide-band decimation filters and 48-bit NCO blocks enable support for multi-band receivers.
