Description
Performance, cost and time to market are key
factors in DSL modem development.
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 (E-
BOM) 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.

The Unicorn II chipset consists of the ST70138
digital chip and the MTC20174 analog front end
with integrated line driver.
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.
Supplied in a compact LBGA80 package, the
ST70138B brings additional cost advantages to
new designs.
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.
