Dual Channel XDSL2 Chip Set
G2237
The XDSL2 ILD2 chip set offers unsurpassed functionality and density for SHDSL. GlobespanVirata’s XDSL2 chip set
provides full G.991.2 (G.shdsl) compliance for both single and dual copper pair systems. In addition to powering
SHDSL products, XDSL2 designs will benefit from full connectivity to legacy SDSL equipment. The XDSL2 chip sets
deliver industry leading performance and interoperability as a result of the underlying architecture and transceiver
firmware.
DSL equipment suppliers will benefit from GlobespanVirata’s high density XDSL2 chip set. Leveraging
GlobespanVirata’s experience in fully programmable DSP’s and high performance AFE’s, designs benefit from
GlobeSpan’s commitment to ongoing product improvements and functional integration through software changes only.
SHDSL offers superior performance to legacy ISDN and SDSL systems though advanced trellis-coding and spectral
efficiency. The benefits of SHDSL’s trellis coding are improved overall reach as well as substantially improved
performance in the presence of noise. Higher performance translates into more customers reached, resulting in
greater revenue potential for service providers. As well as improved performance, SHDSL eliminates the spectral
compatibility issues associated with 2B1Q SDSL. SHDSL has been engineered to coexist with ADSL and HDSL2 in
the public network binders.
GlobespanVirata’s XDSL2 SHDSL chip set provides value added features well beyond the scope of existing DSL
market segments, enabling system vendors to enter new markets and significantly differentiate their offerings.
Examples of such features include IDSL support, provision for rates up to 4.6 Mbps per channel for MTU/MDU appli-
cations, and SHDSL 4 wire support on the same hardware platform.
To accelerate OEM time-to-market, GlobespanVirata provides fully documented, turnkey transceiver reference
designs, development systems, and technical support.
