DM6380 Functional Description
In this chip, we could roughly divide it into two major
parts : digital portion and analog portion. The
functional blocks are described separately in this
section. The analog circuits include a sigma-delta
modulator/demodulator, decimation/interpolation
filters, a speaker driver, low-pass filter and certain
logic circuits. The digital circuits is composed of Tx/Rx
clock generator/PLL, serial port, serial/parallel
conversions and control registers. All the clock
information the analog circuits need should be
provided by the digital clock system since the best
sampling instant of A/D and D/A depends on the
received signal and transmit signals. The data format
of A/D and D/A is 2's complement.
Master clock (FQ) is obtained from an external signal
connected to CLKIN. The different transmit and
receive clocks are obtained by master clock
frequency division in several programmable counters.
The Tx and Rx clocks can be synchronized on
external signals by performing the phase shifts in the
frequency division process. Two independent digital
phase locked loops are implemented using this
principle, one for transmit clock system, the other,
receive clock. The tracking of the transmit clock is
automatically done by the transmit DPLL circuit. The
receive DPLL circuit is controlled by the host
processor and it is actually an adjustable phase
shifter.
