V.22bis/V.22/V.21/Bell 212A/Bell 103

Single-Chip Modem

PARALLEL BUS INTERFACE

synchronous operation as selected. Received data is

processed in a similar fashion except that the rate

converter now acts to reinsert any deleted stop bits

and output data to the terminal at no greater than the

bit rate plus 1%. An incoming break signal (low

through two characters) will be passed through without

incorrectly inserting a stop bit.

Eight 8-bit registers are provided for control, option

select, and status monitoring. These registers are

addressed with the AD0, AD1, and AD2

multiplexed address lines (latched by ALE) and

appear to a control microprocessor as seven

consecutive memory locations. Six control

registers are read/write memory. The detect and

ID registers are read only and cannot be modified

except by modem response to monitored

parameters.

The SYNC/ASYNC converter also has an extended

Overspeed mode which allows selection of an output

overspeed range of either +1% or +2.3%. In the

extended Overspeed mode, stop bits are output at 7/8

the normal width.

SERIAL CONTROL MODE

Both the SYNC/ASYNC rate converter and the data

descrambler are automatically bypassed in the FSK

modes.

The serial Command mode allows access to the

73K224 control and status registers via a serial

control port. In this mode the AD0, AD1, and AD2

lines provide register addresses for data passed

through AD7 (DATA) pin under control of the RD

and WR lines. A read operation is initiated when

the RD line is taken low. The next eight cycles of

EXCLK will then transfer out eight bits of the

selected address location LSB first. A write takes

place by shifting in eight bits of data LSB first for

eight consecutive cycles of EXCLK. WR is then

pulsed low and data transfer into the selected

SYNCHRONOUS MODE

Synchronous operation is possible only in the QAM or

DPSK modes. Operation is similar to that of the

Asynchronous mode except that data must be

synchronized to a provided clock and no variation in

data transfer rate is allowable. Serial input data

appearing at TXD must be valid on the rising edge of

TXCLK.

TXCLK is an internally derived 1200 or 2400 Hz signal

in Internal mode and is connected internally to the

RXCLK pin in Slave mode. Receive data at the RXD

pin is clocked out on the falling edge of RXCLK. The

DTMF GENERATOR

The DTMF generator controls the sending of the

sixteen standard DTMF tone pairs. The tone pair

sent is determined by selecting TRANSMIT DTMF

(bit D4) and the 4 DTMF bits (D0-D3) of the TONE

gated by the TRANSMIT ENABLE bit of CR0 (bit

D1) as with all other analog signals.

asynch/synch

converter

bypassed

when

Synchronous mode is selected and data is transmitted

at the same rate as it is input.
