DESCRIPTION  
The DS1075-IND EconOscillator/Divider is a fixed frequency oscillator requiring no external  
components for operation. Numerous operating frequencies are possible in the range of approximately  
30kHz to 100 MHz through the use of an on-chip programmable prescaler and divider.  
The DS1075-IND features a master oscillator followed by a prescaler and then a programmable divider.  
The prescaler and programmable divider are user-programmable with the desired values being stored in  
non-volatile memory. This allows the user to buy an off the shelf component and program it on-site prior  
to board production. Design changes can be accommodated on the fly by simply programming different  
values into the device (or reprogramming previously programmed devices).  
The DS1075-IND is shipped from the factory configured for half the maximum operating frequency.  
Contact the factory for specially programmed devices. As alternatives to the on-board oscillator an  
external clock signal or a crystal may be used as a reference. The choice of reference source (internal or  
external) is user-selectable at the time of programming (or on the fly if the SEL mode is chosen).  
The DS1075-IND features a dual-purpose Input/Output pin. If the device is powered up in Program  
mode this pin can be used to input serial data to the on chip registers. After a Write command this data is  
stored in non-volatile memory. When the chip is subsequently powered up in operating mode these  
values are automatically restored to the on-chip registers and the Input/ Output pin becomes the oscillator  
output.  
The DS1075-IND is available in 8-pin DIP or SOIC packages, allowing the generation of a clock signal  
easily, economically and using minimal board area.
