General Information
Introduction
The PSB 2163 ARCOFI
®
-SP provides the subscriber with an optimized Audio, Ringing,
Codec, Filter processor solution for a digital telephone. It fulfills all the necessary
requirements for the completion of a low-cost digital telephone.
Please note: Throughout this whole document “ARCOFI
” refers to ARCOFI
-SP
®
®
PSB 2163.
The ARCOFI performs all coding, decoding and filtering functions according to the
CCITT and ETSI (NET33) norms.
Full featured applications are possible without any external elements. All the necessary
hardware and software is implemented. In addition the ARCOFI offers a speakerphone
and monitoring function. This feature is completely digitally implemented in the chip.
Two transducer correction filters (one for each direction) can be programmed to correct
the analog transducer frequency characteristics.
The ARCOFI provides a universal DTMF, tone and ringing generator for the receive
direction. The signal forms available are DTMF, square, trapezoid and sine wave.
Complex signal sequences are made possible by a control generator (e.g. pulsed three
tone call in conjunction with the beat generator).
A DTMF-generator for the transmit direction is also available. If the transmit
DTMF-generator is active, only a part of the receive tone generator function is possible.
This flexible tone generator concept fulfills a wide range of applications.
The interfacing to a handset mouth and earpiece is facilitated by a flexible analog front
end. A loudspeaker output has also been integrated on the chip as well as a secondary
input for a handsfree microphone. All analog inputs and outputs are gain programmable
through software.
At the digital side an ISDN-Oriented Modular (IOM
®
-2) interface for terminal (TE) and
non-terminal (non-TE) applications or a Serial Control/Data Interface (SCI & SDI) is
realized to connect layer-1/2 devices to the ARCOFI.
The ARCOFI is a BlCMOS-device, available in a P-DIP-28, P-LCC-28-R or P-DSO-28
package. It operates from a single + 5 V supply and features a power-down state with
very low power consumption.
