Boosting upstream data rates
In a move to help provide higher upstream internet data rates, Ikanos has launched what it claims is the first single chip integrated front end supporting VDSL2/ADSL2+ gateways.
Changing internet usage modes, including uploading and downloading of video content, mean there is more pressure on service providers to support higher upstream data rates.
In a move to help service providers offer these features, whilst reducing capital expenditure, Ikanos has launched the FXS60IF1, which it says is the first single chip integrated front end (IFE) that enables cost effective, low power, multimode VDSL2/ADSL2+ triple play residential gateways.
Peter Ahimovic, senior director of strategic marketing, pictured, noted: “Service providers are adding services such as VoIP and IPTV, but these need bandwidth and therefore VDSL2. The FXS601F1 services their xDSL requirements.”
The single chip device integrates a/d and d/a converters, along with the filters and line drivers needed for xDSL operation. Ahimovic added: “VDSL2 is still in working text, but we don’t see any reason why this chip will not meet the requirements.”
When used alongside a residential gateway processor such as Ikanos’ FusivVx180, the device supports VDSL2, ADSL2+, ADSL2 and ADSL, as well as offering high levels of impulse noise protection, Rapid Rate Adaptation, on chip QoS and wire speed network processor performance.
