Xilinx Inc. has rolled out its gigabit class 1024QAM point-to-point (PtP) microwave modem IP aimed at backhaul applications. Powered by the company's 28nm All Programmable devices, this modem solution represents an opportunity for wireless OEMs to incorporate differentiated, flexible and programmable capabilities in their cost-sensitive and performance-driven microwave backhaul platforms, stated the company.

The 1024QAM modem IP solution claims to incorporate 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 BOM reduction of up to 30 per centwhen compared to ASSP-based products. Aimed at PtP 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 1Gb/s in a single polarisation and 2Gb/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.

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