DESCRIPTION

The DS1073 is a fixed-frequency oscillator requiring no external components for operation. Numerous

operating frequencies are possible in the range of approximately 27.3kHz to 100MHz through the use of

an on-chip programmable prescaler and divider.

The DS1073 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 DS1073 is shipped from the factory configured for half the maximum operating frequency. Contact

the factory for specially programmed devices. As alternatives to the onboard 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 DS1073 features a dual-purpose I/O 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 I/O pin becomes the oscillator output.

The DS1073 may be operated over either the commercial (T_A= 0C to 70C) or industrial (T_A= -40C to +

85C) temperature ranges. AC and DC Electrical Characteristics Tables for operation in both these

temperature ranges are given at the end of the data sheet.
