GENERAL DESCRIPTION
The AD73411 is a single device incorporating a single analog front
end (AFE) and a microcomputer optimized for digital signal
processing (DSP) and other high-speed numeric processing
applications.
The AD73411’s analog front end (AFE) section is suitable for
general-purpose applications including speech and telephony.
The AFE section features a 16-bit A/D converter and a 16-bit
D/A converter. Each converter provides 76 dB signal-to-noise
ratio over a voiceband signal bandwidth.
The AD73411 is particularly suitable for a variety of applications
in the speech and telephony area, including low bit rate, high-
quality compression, speech enhancement, recognition, and
synthesis. The low group delay characteristic of the AFE makes
it suitable for single or multichannel active control applications.
The A/D and D/A conversion channels feature programmable
input/output gains with ranges of 38 dB and 21 dB respectively.
An on-chip reference voltage is included to allow single supply
operation.
The sampling rate of the AFE is programmable with four sepa-
rate settings offering 64, 32, 16, and 8 kHz sampling rates (from
a master clock of 16.384 MHz) while the serial port (SPORT2)
allows easy expansion of the number of I/O channels by cascad-
ing extra AFEs external to the AD73411.
The AD73411’s DSP engine combines the ADSP-2100 family
base architecture (three computational units, data address gen-
erators, and a program sequencer) with two serial ports, a 16-bit
internal DMA port, a byte DMA port, a programmable timer,
Flag I/O, extensive interrupt capabilities, and on-chip program
and data memory.
The AD73411-80 integrates 80K bytes of on-chip memory
configured as 16K words (24-bit) of program RAM, and 16K
words (16-bit) of data RAM. The AD73411-40 integrates
40K bytes of on-chip memory configured as 8K words (24-
bit) of program RAM, and 8K words (16-bit) of data RAM.
Power-down circuitry is also provided to meet the low power
needs of battery-operated portable equipment. The AD73411
is available in a 119-ball PBGA package.
