73M1903

Modem Analog Front End

DATA SHEET

SEPTEMBER 2006

DESCRIPTION

FEATURES

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.

•

Up to 56kbps (V.92) performance

Programmable sample rates (7.2 - 14.4kHz)

Reference clock range of 9-40MHz

Crystal frequency range of 9-27MHz

Host synchronous serial interface operation

Pin compatible with 73M2901CL/CE

modems

•

Low power modes

On board line interface drivers

Fully differential receiver and transmitter

Drivers for transformer interface

3.0V – 3.6V operation

The device incorporates

programmable

•

sample rate circuit to support soft modem and

DSP based implementations of all speeds up to

V.92 (56kbps). The sampling rates supported

are from 7.2kHz to 14.4kHz by programming

pre-scaler NCO and PLL NCO.

5V tolerant I/O

Industrial temperature range (-40 to +85°C)

JATE compliant transmit spectrum

Package options: 32-TQFP and 32-QFN

The TERIDIAN 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.

APPLICATIONS

•

Set Top Boxes

Personal Video Recorders (PVR)

Multifunction Peripherals (MFP)

Fax Machines

Cost saving features of the device include an

input reference frequency circuit, which accepts

a range of crystals from 9-27MHz. It also

accepts external reference clock values between

9-40MHz 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 in 32-TQFP package is footprint

compatible with 73M2901CL embedded modem

and allows for the same circuit design to

accommodate soft modem, V.22bis hard

modem, and high speed (V.32bis/V.34/V.92)

applications through population of an external

data pump device.
