Extended Temperature Serial Interface CODEC/Filter

COMBO^®Family

General Description

Features

n −40˚C to +85˚C operation

The TP3054, TP3057 family consists of µ-law and A-law

monolithic PCM CODEC/filters utilizing the A/D and D/A

conversion architecture shown in Figure 1, and a serial PCM

interface. The devices are fabricated using National’s ad-

vanced double-poly CMOS process (microCMOS).

n Complete CODEC and filtering system (COMBO)

including:

— Transmit high-pass and low-pass filtering

— Receive low-pass filter with sin x/x correction

— Active RC noise filters

The encode portion of each device consists of an input gain

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

high frequency noise prior to entering a switched-capacitor

band-pass filter that rejects signals below 200 Hz and above

3400 Hz. Also included are auto-zero circuitry and a com-

panding coder which samples the filtered signal and en-

codes it in the companded µ-law or A-law PCM format. The

decode portion of each device consists of an expanding

decoder, which reconstructs the analog signal from the com-

panded µ-law or A-law code, a low-pass filter which corrects

for the sin x/x response of the decoder output and rejects

signals above 3400 Hz followed by a single-ended power

amplifier capable of driving low impedance loads. The de-

vices require two 1.536 MHz, 1.544 MHz or 2.048 MHz

transmit and receive master clocks, which may be asynchro-

nous; transmit and receive bit clocks, which may vary from

64 kHz to 2.048 MHz; and transmit and receive frame sync

pulses. The timing of the frame sync pulses and PCM data is

compatible with both industry standard formats.

— µ-law or A-law compatible COder and DECoder

— Internal precision voltage reference

— Serial I/O interface

— Internal auto-zero circuitry
