TP5510

Full Duplex Analog Front End (AFE)

for Consumer Applications

General Description

Features

Complete A/D and D/A with filter system including:

Ð Serial Data Interface

The TP5510 consists of a m-law monolithic AFE device uti-

lizing the A/D and D/A conversion architecture shown in

Figure 1, and a serial data interface. The device is fabricat-

ed using National’s advanced double-poly CMOS process

(microCMOS).

Ð Encode high-pass and low-pass filter

Ð Decode low-pass filter with sin x/x correction

Ð Active RC noise filters

Ð m-law compatible A/D and D/A

Ð Internal precision voltage reference

Ð Internal auto-zero circuitry

The A/D portion of the device consists of an input gain

adjust amplifier, an active RC pre-filter which eliminates very

high frequency noise, and a switched-capacitor band-pass

filter that rejects signals below 200 Hz and above 3400 Hz.

Also included are auto-zero circuitry and a compressing

A/D which samples the filtered signal and converts it to the

m-law digital format. The decode portion of the device con-

sists of an expanding D/A, which reconstructs the analog

signal from the compressed m-law code, a low-pass filter

which corrects for the sin x/x response of the D/A output

and rejects signals above 3400 Hz, followed by a single-

ended power amplifier capable of driving low impedance

loads. The device requires a 1.536 MHz, 1.544 MHz or

2.048 MHz master clock, bit clocks which may vary from 64

kHz to 2.048 MHz; and 8 kHz frame sync pulses.
