These chip sets are fully programmable and field upgradeable eliminating the risk of product obsolescence and accelerating the time-to-market for new network services. The GlobespanVirata® XDSL2™ DSL chip sets are fully interoperable with multi-vendor DSL chip set solutions. This interoperability enables dynamic interworking of multiple vendor DSL solutions with the capability to interoperate with products that conform to ANSI and ETSI DSL standards. GlobespanVirata’s unique hardware platform supports multiple dual-channel applications including SDSL, HDSL2, and SHDSL, using population options for optimization. The XDSL2 DSL chip sets incorporate two DSL bit pumps plus framing into a three-chip solution comprised of a dualchannel digital signal processor (DSP) with built-in framer and two Analog Front Ends each with an Integrated Line Driver (ILD2). The XDSL2 chip sets interface directly with off-the-shelf T1/ E1 transceivers and Nx64 multiplexing, eliminating the need for a separate DSL framer to combine and format the two DSL channels into a standard interface. GlobespanVirata’s DSL XDSL2 chip sets deliver two channels of full duplex transmission up to 2320 kb/s, depending on the application. The high density XDSL2 dual-channel DSL chip sets are ideal for CO applications, while single-channel versions with integrated framer are also available for CPE applications. Data Sheet Features • • • • • • • • • • • • • • Dual-channel DSP with framer that fully integrates 2 separate DSL chips into a single device Two AFEs, each with an integrated differential line driver 2B1Q, CAP, or PAM line codes Supports dual-channel symmetric data rates of 144 kb/s to 2320 kb/s (depending on the application) Supports IDSL with optional data interface rates of 64 kb/s, 128 kb/s, and 144 kb/s Offers physical layer interoperability with competitive solutions Glueless interface to popular microprocessors Transmission compliant with ETSI TS 101 135, ITU-T G.991.1, and ANSI TR-28 for single pair 2B1Q and CAP, ANSI T1.418 for HDSL2 and ITU-T G.991.2 for SHDSL Reference design compatible with Bellcore GR-1089, IEC 60950, UL 1950, ITU-T K.20 and K.21 Built-in framer provides easy access to EOC and indicator bits (framing can be bypassed completely for 2-channel independent operation) Interfaces directly with off-the-shelf single-channel T1/E1 transceivers ATM UTOPIA Level 1 and 2 interface A single oscillator and hybrid topology supports all speeds +3.3V and +5V power supplies TDATA (A/B) TClock (A/B) Frame Pulse (A/B) Customer Interface RDATA.
