DESCRIPTION
The DS1075 is a fixed frequency oscillator requiring no
external components for operation. Numerous operat-
ing frequencies are possible in the range 0.2 to 100 MHz
through the use of an on–chip programmable prescaler
and divider.
The DS1075 features a master oscillator followed by a
prescaler and then a programmable divider. The pres-
caler and programmable divider are user–program-
mable with the desired values being stored in non–vola-
tile memory. This allows the user to buy an off the shelf
component and program it on site prior to board produc-
tion. Design changes can be readily accommodated by
programming, or reprogramming, the desired values
into the on–chip non–volatile registers. An evaluation
board, DS1075K is available to simplify this task.
The DS1075 is shipped from the factory configured for
half the maximum operating frequency. Pre–pro-
grammed devices can be ordered on a custom basis as
DS1075C–xxx. As alternatives to the on–board oscilla-
tor 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 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 is available in 8–pin DIP or SOIC pack-
ages, allowing the generation of a clock signal easily,
economically and using minimal board area.
