Signal Description
The Teridian 73M1903 modem AFE IC is available in a 20-pin TSSOP or 32-pin QFN package with the
same pin out. The following table describes the function of each pin. There are two pairs of power
supply pins, VPA (analog) and VPD (digital). They should be decoupled separately from the supply
source in order to isolate digital noise from the analog circuits internal to the chip. Failure to adequately
isolate and decouple these supplies will compromise device performance.
