www.DataSheet4U.com ST20138 Unicorn II DATA BRIEF PCI/USB ADSL CHIPSET: ST70138 + MTC20174 FOR ULTRA LOW COST ADSL MODEM 1 DESCRIPTION The Unicorn II chipset consists of the digital ST70138 chip and the MTC20174 analog front end. The ST70138 is supplied in two packages, TQFP144 and LBGA80. 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.
