2 / 26 page  STLC1512 2/26 1.0 GENERAL DESCRIPTION The line driver transmit path contains a preamplifier followed by a power output stage. The power stage has current outputs that directly drive the primary side of a center tapped transformer. The receive path contains a programmable gain am- plifier followed by an opamp which is used with off chip passive components in an active low pass filter. The Programmable Grain Amplifier (PGA) has four steps optimized for the recommended G.lite CO line interface. There is also an undedicated opamp which can be used for active filtering in either the transmit or re- ceive paths 2.0 PACKAGING AND PIN INFORMATION 2.1 Package Technology STLC1512 will be packaged in a TQFP 48 package, according to JEDEC Specification reference MS- 026-BBC. 2.2 STLC1512 Pin Allocation The pin out for the STLC1512 is depicted in the fol- lowing Figure 2.
