DESCRIPTION
The Teridian 73M1903 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
14.4 kHz by programming pre-scaler NCO and PLL
NCO.
The 73M1903 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.
Cost-saving features of the device include an input
reference frequency circuit, which accepts a range
of crystals from 9-27 MHz. It also accepts external
reference clock values between 9-40 MHz
generated by the host processor. In most
applications, this eliminates the need for a dedicated
crystal oscillator and reduces the bill of material
(BOM).
The 73M1903 also supports two analog loop back
and one digital loop back test modes.
