Description

The DDC SDA 9064-5 consists essentially of a processor with program ROM and RAM, ports for input and output signals and a clock rate divider that supplies the whole chip with clock signals.

The processor is specially manufactured for the arithmetic operations performed in the DDC. SDA 9064-5 operates according to the pipeline principle on account of the high requirements involved with regard to time. SDA 9064-5 has two 16-bit accumulators. The 16-bit data bus and the 7-bit address bus take care of the data traffic between the processor and the ports. The size of the static RAM is 96 x 16 bits; the program ROM can store 800 16-bit instructions.

The V port and the 2 port of SDA 9064-5 comprise counters for coarse conversion and a chain of 32 resistors for amplitute quantization of fine conversion. The 2 port further measures the position of the ZR pulses with respect to time and transfers measured data to the processor. The east/west port similarly of SDA 9064-5 has a counter for digital time conversion but manages without fine conversion.

The 9-bit analog-to-digital converter SDA 9064-5 works on the principle of successive approximation using a capacitance field.

The I²C Bus SDA 9064-5 interface makes it possible to read and modify deflection data in the RAM. The protective circuitry monitors inputs SS, ZR and HA2EN using comparators.

The start-up circuitry of SDA 9064-5 has its own power and clock pulse supply. It is therefore completely independent of the other DDC functions.
