General Description
The TP3054 TP3057 family consists of m-law and A-law
monolithic PCM CODECfilters utilizing the AD and DA
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)
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 m-law or A-law PCM format The
decode portion of each device consists of an expanding
decoder which reconstructs the analog signal from the
companded m-law or A-law code a low-pass filter which
corrects for the sin xx 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 devices require two 1536 MHz 1544 MHz or 2048
MHz transmit and receive master clocks which may be
asynchronous transmit and receive bit clocks which may
vary from 64 kHz to 2048 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
