ML7012-04

2400 bps Single Chip Full Duplex Data Modem with Protocol

1/22

GENERAL DESCRIPTION

The ML7012-04 is a single chip modem LSI device that enables data communication conforming to ITU-T
recommendations V.22bis, V.22, and V.21. This device is equipped with the error correction protocol function
conforming to MNP Class 4. (The MNP Class 4 can be used for V.22bis or V.22.)

The ML7012-04 consists of high speed DSP, analog front end, and digital logic circuit. In addition, this device
provides local analog loop testing, synchronous/asynchronous switching, dialing, and auto answering functions.

The ML7012-04 has a serial interface as an external interface. When integrated into the system, it is controlled
from a control CPU through a serial interface (e.g. UART). By connecting a level converter, the ML7012-04 can
easily implement a modem that can be controlled through the RS-232C interface.

COMMAND DESCRIPTIONS

AT Commands

(1) Command format
AT commands begin with <AT> or <at>. Character strings to a carriage return code are interpreted as commands
to be executed successively. A result code is returned to DTE after the completion of interpretations.

Characters

However, the commands of A, D, Dc, On, Zn, Ax, &Tn and &Zn must be set at the end of the sequence of
commands.
Any commands set after those commands are ignored.

The maximum command character string is 40 characters (space <20h> is ignored).
Input characters can be deleted by a backspace function (a cord is changeable).
<CR> is a Carriage Return code (changeable).
<LF> is a Line Feed code (not mandatory and changeable).

Both capital and small letters can be recognized with the exception of At and aT. The communication with the
terminal when inputting commands is handled as an asynchronous mode, and the character format is checked
automatically as soon as <AT> or <at> is input.

This device cannot be guaranteed for normal operation when character strings or parameters not listed below are
input.

(2) Terminal data speed and character format
The communication mode to DTE with the V.24 interface is as follows:
Terminal data speed: 9600/2400/1200/300 bps

Examples of Level Diagram

(1) Modem transmit: V

3 V

AOUT = 20 dBm, RCAO = 20 dBm, TXAN = 14 dBm, TXAP = 14 dBm, LINE = 16 dBm
(S34 = 2 dB (initial value), R5/R4 = 2, transformer loss = 2 dB)

(2) DTMF transmit: V

3 V: high group level

The low group levels are approximately 1 dB smaller than the values below.
AOUT = 14.5 dBm, RCAO = 14.5dBm, TXAN = 8.5 dBm, TXAP = 8.5 dBm, LINE = 10.5 dBm
(S35 = 0 dB (initial value), R5/R4 = 2, transformer loss = 2 dB)

(3) Modem transmit: V

2.7 V

AOUT = 20 dBm, RCAO = 20 dBm, TXAN = 15.9 dBm, TXAP = 15.9 dBm, LINE = 17.9 dBm
(S34 = 2 dB (initial value), R5/R4 = 1.6, transformer loss = 2 dB)

(4) DTMF transmit: V

2.7 V: high group level

The low group levels are approximately 1 dB smaller than the values below.
AOUT = 14.5 dBm, RCAO = 14.5 dBm, TXAN = 10.4 dBm, TXAP = 10.4 dBm, LINE = 12.4 dBm
(S35 = 0 dB (initial value), R5/R4 = 1.6, transformer loss 2 dB)

(5) Maximum modem receive:

LINE = 9 dBm, connecting point of R6, and R7 = 11 dBm, GSR = 15 dBm
(R8/R7 = 0.63 = 4 dB, transformer loss = 2 dB)

(6) Minimum modem receive

LINE = 40 dBm, connecting point of R6 and R7 = 42 dBm, GSR = 46 dBm
(R8/R7 = 0.63 = 4 dB, transformer loss = 2 dB)

Connection of Crystal Oscillator

Connect a 11.0592 MHz crystal unit and a 1 M

feedback resistor between OSC0 and OSC1.

The values of capacitors C

and C

connected between OSC0 and GND, and OSC1 and GND vary with the load

capacitance of the crystal unit and the wiring capacitance of the board. Set the values by the crystal manufacture's
matching evaluation.
If an external clock is used, input it to OSC0.

Notes for Mounting the Surface Mount Type Package

The surface mount type packages are very susceptible to heat in reflow mounting and humidity
absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product
name, package name, pin number, package code and desired mounting conditions (reflow method,
temperature and times).
