9 / 20 page 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. |
