STLC1512
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-
