MC145483
3 V 13-Bit Linear PCM
Codec-Filter
The MC145483 is a 13–bit linear PCM Codec–Filter with 2s complement data
format, and is offered in 20–pin SOG, SSOP, and TSSOP packages, and a
32–pin QFN package. This device performs the voice digitization and
reconstruction as well as the band limiting and smoothing required for the voice
coding in digital communication systems. This device is designed to operate in
both synchronous and asynchronous applications and contains an on–chip
precision reference voltage.
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 13–bit linear A/D converter. The digital output is 2s
complement format.
The decoder digital input accepts 2s complement data and reconstructs it
using a differential 13–bit linear 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 MC145483 PCM Codec–Filter has a high–impedance VAG reference pin
which allows for decoupling of the internal circuitry that generates the
mid–supply VAG reference voltage to the VSS power supply ground. This
reduces clock noise on the analog circuitry when external analog signals are
referenced to the power supply ground.
The MC145483 13–bit linear PCM Codec–Filter accepts both Short Frame
Sync and Long Frame Sync clock formats, and utilizes CMOS due to its reliable
low–power performance and proven capability for complex analog/digital VLSI
functions.
