4.2 DEMO BOARD SCHEMATIC DIAGRAM

There are few variations of 73M1903 Demo boards available. One of them is the Low cost minimum feature US DAA design. And another one is the full-featured CTR21
compliant DAA design with parallel phone pickup detection circuit. And the other is a US High speed DAA design. These schematics are shown here.
