SIGNAL DESCRIPTION
The TERIDIAN 73M1903C modem AFE IC is available in a 32 pin 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.

Master reset. When this pin is a logic 0 all registers are reset to their
default states; Weak-pulled high-default. A low pulse longer than 100ns
is needed to reset the device. The device will be ready within 100us after
this pin goes to logic 1 state.

Serial interface clock. With master mode and SCLK continuous selected,
Freq = 256*Fs ( =2.4576MHz for Fs=9.6kHz). For slave mode, this pin
must be pulled down by a resistor (<4.7k).

Controls the SCLK behavior after FS. Open, weak-pulled high = SCLK
Continuous; tied low = 32 clocks per R/W cycle.
FSBD
O
21
Delayed frame sync to support daisy chain mode with additional
73M1903C devices
