ST20138 Unicorn II USB ADSL modem chipset: ST70138 + MTC20174 for ultra-low-BOM ADSL modem designs Data Brief Description The Unicorn II chipset consists of the ST70138 digital chip and the MTC20174 analog front end with integrated line driver. Performance, cost and time to market are key factors in DSL modem development. The ST70138 is supplied in two packages, LBGA80 and TQFP144. The ST70138T, packaged in TQ144, is pin-compatible to the ST70137 legacy ADSL USB chipset, enabling manufacturers to benefit directly from the cost and performance advantages that the ST70138 brings. The Unicorn II chipset has been designed with all these care-abouts in mind, providing CPE manufacturers with a complete and extremely cost-effective solution for ADSL USB modems operating under a variety of operating systems, such as Microsoft Windows™, Mac OS and Linux. The controller-less architecture of the Unicorn II and the fact that it does not require an external SDRAM, make its external bill-of-materials (EBOM) best-in-class. Thanks to its small form factor packages and an external component count of less than 140, the Unicorn II easily fits on a small-dimension standard 2-layer single-sided PCB which further reduces overall system cost. Combining low power consumption, high-speed performance (up to 8 Mbps), field-proven driver software and customizable user interface, the Unicorn II is the ideal choice for cost-conscious equipment manufacturers, telecom operators/ISPs and ADSL users alike. ) s ( ct Figure 1. c u d o r P The MTC20174 has been designed for use in DMT-based ADSL CPE modems than comply with ANSI T1.413 issue 2, ITU G.992.1 (G.dmt) andITU G.992.2 (G.lite), for Annex A and B, and the DT U-R2 specification. e t le o s b O - Chipset architecture overview u d o r P e ST70138 DMT engine + USB controller t e l o s b O ) s t( Supplied in a compact LBGA80 package, the ST70138B brings additional cost advantages to new designs.

The Unicorn II chipset is succeeding the fieldproven Unicorn, the first controller-less ADSL USB modem chipset that was deployed in volume. Compared to conventional USB ADSL chipsets, the Unicorn II dramatically reduces design and production costs of USB ADSL modems. The chipset which is manufactured in a cost-effective CMOS technology integrates a number of external components which results in reduced component count and PCB complexity. Thus E-BOM costs could be lowered significantly, while overall performance was improved. t e l o s b O Its proven controller-less and SDRAM-less architecture is a key differentiator in today's highly March 2007 ) s t( Thanks to its small form factor packages and an external component count of less than 140, the Unicorn II easily fits on a small-dimension standard 2-layer single-sided PCB which further reduces overall system cost.
