Xilinx Inc. reveals its new Gigabit class 1024QAM point-to-point (PtP) microwave modem IP designed for backhaul applications.

Designed with significant input from Tier 1 OEMs and powered by Xilinx's 28nm All Programmable devices, this modem solution is said to represent a tremendous opportunity for wireless OEMs to incorporate differentiated, flexible and programmable capabilities in their cost-sensitive and performance-driven microwave backhaul platforms.

The 1024QAM modem IP solution incorporates all the key features and capabilities that OEMs require to accelerate development of wireless solutions that consume as much as 30 per cent less power and which have potential total bill-of-materials (BOM) reduction of up to 30 per cent—when compared to ASSP-based products.

Claimed as ideal for point-to-point outdoor deployments, the modem supports legacy interfaces such as multiple E1/T1 and SDH as well as Gigabit Ethernet interfaces. The data rates are scalable to 1Gbit/s in a single polarisation and 2Gbit/s in dual polarized mode. Increased phase noise tolerance enables the cost of equipment to be optimised and the ability to exploit the benefits of higher order modulations in the field.

Key features include supporting modulation from QPSK up to 1024QAM, channel spacing from 3.5 -112MHz, Adaptive Modulation, Adaptive Digital Pre-distortion, Forward Error Correction, I/Q imbalance correction, automatic frequency recovery, hybrid Decision Directed Equaliser, integrated payload and configuration interfaces.

At the heart of the 1024QAM modem IP solution is Xilinx's All Programmable 7 series devices, built on the state-of-the-art 28nm High Performance, Low-Power (HPL) process technology to deliver breakout performance, capacity and system integration while optimising price, performance and power consumption.

The 1024QAM modem IP solution is available now for select customers and general availability is expected by May 2013.
