DESCRIPTION
The 73M1903C Analog Front End (AFE) IC includes
fully differential hybrid driver outputs, which connect to
the telephone line interface through a transformer-
based DAA. The receive pins are also fully differential
for maximum flexibility and performance. This
arrangement allows for the design of a high
performance hybrid circuit to improve signal to noise
performance under low receive level conditions, and
compatibility with any standard transformer intended
for PSTN communications applications.
The device incorporates a programmable sample rate
circuit to support soft modem and DSP based
implementations of all speeds up to V.92 (56 kbps).
The sampling rates supported are from 7.2 kHz to
16.0 kHz by programming the pre-scaler NCO and the
PLL NCO.
The 73M1903C device incorporates a digital host
interface that is compatible with the serial ports found
on most commercially available DSPs and processors
and exchanges both payload and control information
with the host. This interface can be configured as a
single master/slave mode or as a daisy chain mode
that allows the user to connect up to eight 73M1903C
devices to a single host for multi Analog Front End
applications, such as, central server modems.
Costs saving features of the device include an input
reference frequency circuit, which accepts a range of
crystals from 4.9-27 MHz. It also accepts external
reference clock values between 1 MHz and 40 MHz
generated by the host processor. In most
applications, this eliminates the need for a dedicated
crystal oscillator and reduces the bill of materials
(BOM).
The 73M1903C also supports two analog loop back
and one digital loop back test modes.
