73M2901CL

V.22bis Single Chip Modem

but no clocks will be supplied to the CPU. Instruction

processing and activity on the internal busses is

halted. Normal operation is resumed when an

interruption such as assertion of '75 or 5,1*, a

character is sent to the 73M2901CL TXD input, or a

reset occurs.

HARDWARE DESCRIPTION

The 73M2901CL is designed to operate from a +3.6

to +2.7 volt supply with low power consumption

(~30mW @ 3.0 volts). The modem supports

automatic standby idle mode. The modem will also

accept a request to power down from the DTE via

hardware control. No additional major components

are required to complete the modem core logic. The

modem provides direct firmware LED support via

port pins.

ANALOG LINE / HYBRID INTERFACE

The 73M2901CL provides a differential analog

output (TXAP and TXAN) and a single-ended analog

input (RXA) with internal A/D and D/A converters. A

driver is provided for an internal hybrid function.

HARDWARE FEATURES

The internal hybrid driver is capable of driving an

external load matching impedance and a line-

coupling transformer. The internal hybrid/line driver

senses the load and adapts itself to its requirements.

•

Fully self-contained. “AT” Command interpreter

and data pump

•

User pins available

Synchronous serial data I/O available

Asynchronous serial port

The 73M2901CL provides firmware control for a

hook relay driver (5(/$<) as well as interrupt

support for a ring detect opto-coupler (5,1*).

On-chip hybrid and line driver.

Autobaud capability from 300bps to 9600bps

INTERRUPT PINS

The external interrupt sources, '75 and 5,1*,

come from dedicated input pins of the same name.

POWER SUPPLY

Power is supplied to the 73M2901CL via the VPD

and VPA pins. The 73M2901CL is designed for a

single +3.6 to +2.7 volt supply and for low power

consumption (~30mW @ 3.0 volts). Ground is

supplied to the 73M2901CL via VND and VNA pins.

DTR informs the 73M2901CL that the host has

requested the 73M2901CL perform a specific

function. The function of '75ꢀ can be changed by

“AT” commands (described in full in the TDK

73M2901CL User’s Guide).

The 73M2901CL has been designed with separated

analog and digital supplies to insure the best

performance of the part by using different filtered

power supplies. It is recommended that separate

locally bypassed traces be used to apply power to

the analog supply VPA and the digital supply VPD.

RING is used to inform the 73M2901CL that the

external DAA circuitry has detected a ring signal.

In addition, sending any character on the TXD line

also generates an internal interrupt.

CRYSTAL OSCILLATOR

The TDK 73M2901CL single chip modem can use

an external 11.0592 MHz reference clock or can

generate a clock using only a crystal and two

capacitors. If an external clock is used, it should be

applied to OSCIN.

LOW POWER MODE

The TDK 73M2901CL supports a low power standby

mode. If the low power standby option is enabled the

73M2901CL will go into a power saving mode when

idle. The oscillator will be running, clocks will be

supplied to the UART, timers and interrupt blocks;
