DESCRIPTION
The ST70138T packaged in TQ144 is a pin-to-pin compatible version of the ST70137 enabling manufacturers to benefit directly from the cost and performance advantages that the ST70138 brings. The TQ144 flavor brings out both the USB and PCI interfaces. Supplied in a compact USB-only LBGA80 package, the ST70138B brings additional cost advantages to new designs. The MTC20174 Analog Front End (AFE) with integrated line driver is designed for DMT based ADSL CPE modems compliant with ANSI T1.413 issue 2, ITU G.992.1 (G.dmt) and ITU G.992.2 (G.lite), for Annex A, B and C. The Unicorn II chipset is designed to simplify the development of low-cost ADSL CPE modems for Windows, Mac and Linux based environments and enables manufacturers to achieve a very competitive production cost. Due to its controller-less architecture and particularly the advantage that it does not require an external SDRAM in its E-BOM, the total cost of the external components needed in the modem is the best in its class.
