Advance Information  
P SUFFIX  
PLASTIC DIP  
CASE 738  
The MC14LC5480 is a general purpose per channel PCM Codec–Filter with  
pin selectable Mu–Law or A–Law companding, and is offered in 20–pin DIP,  
SOG, and SSOP packages. This device performs the voice digitization and  
reconstruction as well as the band limiting and smoothing required for PCM  
systems. This device is designed to operate in both synchronous and  
asynchronous applications and contains an on–chip precision reference  
voltage.

DW SUFFIX  
SOG PACKAGE  
CASE 751D  
1
This device has 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 passband 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.  
PIN ASSIGNMENT  
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.  
The MC14LC5480 PCM Codec–Filter accepts a variety of clock formats,  
including Short Frame Sync, Long Frame Sync, IDL, and GCI timing  
environments. This device also maintains compatibility with Motorola’s family of  
Telecommunication products, including the MC14LC5472 U–Interface Trans-  
ceiver, MC145474/75 S/T–Interface Transceiver, MC145532 ADPCM Trans-  
coder, MC145422/26 UDLT–1, MC145421/25 UDLT–2, and MC3419/MC33120  
SLIC.  
The MC14LC5480 PCM Codec–Filter utilizes CMOS due to its reliable  
low–power performance and proven capability for complex analog/digital VLSI  
functions.
