AD1970
Rev. 0 | Page 9 of 20
THEORY OF OPERATION
The AD1970 is comprised of a BTSC encoder with stereo
analog inputs and a sync separator to derive the pilot signal
from the composite video stream. Figure 1 shows the block
diagram of the device.
Signal processing parameters are stored in a parameter RAM,
which is initialized on power-up by an internal boot ROM. The
values stored in the parameter RAM control all the filter coef-
ficients, mixing, and dynamics-processing code used in the
BTSC algorithm.
The AD1970 has an I2C port that supports complete read/write
capability of the parameter RAM, as well as a control port and
several other registers that allow the various signal processing
parameters to be controlled. The AD1970 can run as a stand-
alone processor without external control.
The AD1970 has a very flexible serial data input port that allows
for glueless interconnection to a variety of digital signal sources.
The AD1970 can be configured in left-justified, I2S, right-
justified, or DSP serial port-compatible modes. It can support
16, 20, and 24 bits in all modes. The AD1970 accepts serial
audio data in MSB first, twos complement format.
The AD1970 operates from a single 3.3 V power supply. It is
fabricated on a single monolithic integrated circuit and is
housed in a 48-pin LQFP package for operation over the
temperature range of 0°C to 70°C.
