DESCRIPTION

The DS1065 is a fixed frequency oscillator requiring no external components for operation. Numerous

operating frequencies are possible in the range of approximately 30 kHz to 100 MHz through the use of

an on-chip programmable prescaler and divider.

The DS1065 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

nonvolatile 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 easily by simply programming different

values into the device (or reprogramming previously programmed devices). The DS1065 is shipped from

the factory configured for half the maximum operating frequency. Contact the factory for specially

programmed devices.

The DS1065 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

nonvolatile 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 DS1065 is available in TO-92 (3 LEAD) package, allowing the generation of a clock signal easily,

economically and using minimal board area.
