1 / 7 page 1/7 ST20190 June 2004 This is preliminary information on a new product now in development. Details are subject to change without notice. 1 APPLICATIONS ■ Low end and high end ADSL Bridge and Router solutions ■ ADSL Modems / routers for residential and SOHO broadband access to www and corporate VPNs ■ Integrated Access Devices offering VoDSL or VoIP applications ■ Home gateway solutions 2 FEATURES ■ High Integration – 2 chips, Line to ATM – Direct ATM Interface – Line Driver integrated – Highly reduced bill of material cost ■ Support for multiple ADSL standards: – ANSI T1.413 Issue2 – ITU G.992.1 (G.dmt) – Annex A, Annex B, Annex C – ITU G.992.2 (G.Lite) – ITU G.992.3 (ADSL2) – Annex A, B, C, I, J and L – ITU G.992.4 (G.Lite bis) – ITU G.992.5 (ADSL2+) – Annex A, B, C, I, J and L – Support of ReachDSLTM with digital com- panion chip ■ Cat II functionality: Trellis coding and echo cancellation ■ Dual latency support: fast + interleaved ■ Small footprint packages allow high density board designs ■ Embedded controller with cache for powerful and flexible on chip control of the modem operation ■ Complete modem package – No dependency on external processor and easy,straight forward integration with external network processors – Full reference design kit for modem manufac- turers, including schematics, layout, BoM, HW design guide, firmware ■ Highest Performance – Fully rate-adaptive – ADSL mode > 12 Mbps in Downstream and > 1 Mbps in Upstream – ADSL+ mode > 20 Mbps in Downstream and > 2 Mbps in Upstream when using 64 tones (annex L) 3 OVERALL DESCRIPTION The ST20190 is a new generation ADSL chipset from STMicroelectronics. It is highly integrated and has the flexibility to offer all standards, all an- nexes while being fully optimised for CPE applica- tions. It provides all the required functions to implement a complete Utopia rate adaptive DMT ADSL modem. It consists of the optimised ADSL Analogue Front-End chip ST20184 and the digital chip ST20196 which includes a DMT/ATM mo- dem, and a dedicated ADSL Transceiver Control- ler with associated Firmware. As shown in Fig.2, the chipset interfaces have been defined to allow direct integration into sys- tems design, reducing both time-to-market and im- DATA BRIEF ADSL, ADSL2 and ADSL+ Modem Chipset for CPE Applications with Utopia II Interface REV. 1 Figure 1.
