T8301 Internet Protocol Telephone

Phone-On-A-Chip™

IP Solution DSP

_■Dual-port RAM, 6K x 16 (zero wait-state at

80 MHz).

1 Introduction

Lucent Technologies’

IP Solution

Phone-On-A-Chip

_■Internal SRAM, 16K x 16 (single wait-state at

80 MHz).

is a highly integrated set of IC chips that form the

basic building blocks for an internet protocol tele-

phone (IPT), residing on a local area network (LAN).

_■16-bit analog-to-digital converter.

_■Programmable gain amplifier on audio input.

_■Fixed gain differential microphone input.

_■Analog input SRAM buffer, 512 x 16.

_■Timed DMA for analog input SRAM.

_■Two 16-bit digital-to-analog converters.

The IPT presently consists of two ICs—the T8301

(IPT_DSP) and the T8302 (IPT_

*).

ARM

The T8301 provides the audio processing engine for

voice compression and decompression, speaker-

phone echo cancellation, digital-to-analog and ana-

log-to-digital converters, low-pass filters, and

amplifiers to drive standard business telephone

handsets and speakerphone hardware.

_■Independent simultaneous speaker and handset

outputs.

The general-purpose processor chip T8302 controls

system I/O (Ethernet, USB, IrDA, etc.) and provides

general telephone control features (LED control, key-

pad button scanning, LCD module interface, etc.).

_■Two integrated differential speaker driver outputs.

_■Two analog output SRAM buffers, 512 x 16 each.

_■Two timed DMA outputs for simultaneous handset

and speaker audio output.

A block diagram of the T8301 can be found in

Figure 3 on page 8.

_■Low-pass filtering on audio inputs and outputs.

_■Serial I/O interface.

Since the DSP1627 is an integral part of the T8301,

we will refer to the

DSP1627 Digital Signal Processor

Data Sheet throughout this discussion.

_■General-purpose timer counter.

_■Bit I/O interface.

1.1 Features

_■JTAG test and debugging control.

_■Implementation in 0.35 m, 5 V silicon technology.

_■DSP1627 core with bit manipulation unit.

_■DSP clock speeds up to 80 MHz.

_■Packaged in 100-pin TQFP.

_■Instruction ROM, 32K x 16 (zero wait-state

at 80 MHz).
