SEMICONDUCTOR TECHNICAL DATA  
The MC145554, MC145557, MC145564, and MC145567 are all per channel  
PCM Codec–Filters. These devices perform the voice digitization and  
reconstruction as well as the band limiting and smoothing required for PCM  
systems. They are designed to operate in both synchronous and asynchronous  
applications and contain an on–chip precision voltage reference. The  
MC145554 (Mu–Law) and MC145557 (A–Law) are general purpose devices  
that are offered in 16–pin packages. The MC145564 (Mu–Law) and MC145567  
(A–Law), offered in 20–pin packages, add the capability of analog loopback and  
push–pull power amplifiers with adjustable gain.

CASE 620  
These devices have an input operational amplifier whose output is the input  
to the encoder section. The encoder section immediately low–pass filters the  
analog signal with an active R–C filter to eliminate very–high–frequency noise  
from being modulated down to the pass band by the switched capacitor filter.  
From the active R–C filter, the analog signal is converted to a differential signal.  
From this point, all analog signal processing is done differentially. This allows  
processing of an analog signal that is twice the amplitude allowed by a  
single–ended design, which reduces the significance of noise to both the  
inverted and non–inverted signal paths. Another advantage of this differential  
design is that noise injected via the power supplies is a common–mode signal  
that is cancelled when the inverted and non–inverted signals are recombined.  
This dramatically improves the power supply rejection ratio.

After the differential converter, a differential switched capacitor filter band  
passes the analog signal from 200 Hz to 3400 Hz before the signal is digitized  
by the differential compressing A/D converter.  
The decoder accepts PCM data and expands it using a differential D/A  
converter. The output of the D/A is low–pass filtered at 3400 Hz and sinX/X  
compensated by a differential switched capacitor filter. The signal is then filtered  
by an active R–C filter to eliminate the out–of–band energy of the switched  
capacitor filter.

These PCM Codec–Filters accept both long–frame and short–frame industry  
standard clock formats. They also maintain compatibility with Motorola’s family  
of TSACs and MC3419/MC34120 SLIC products.  
The MC145554/57/64/67 family of PCM Codec–Filters utilizes CMOS due to  
its reliable low–power performance and proven capability for complex  
analog/digital VLSI functions.
