SIGNAL DESCRIPTION
The TERIDIAN 73M1903 modem AFE IC is available in a 32 pin TQFP or QFN package with 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 separately decoupled 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.
