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鈥揷hip 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鈥損rogram-
mable with the desired values being stored in non鈥搗ola-
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鈥揷hip non鈥搗olatile 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鈥損ro-
grammed devices can be ordered on a custom basis as
DS1075C鈥搙xx. As alternatives to the on鈥揵oard 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鈥搒electable at the time of programming
(or on the fly if the SEL mode is chosen).
The DS1075 features a dual鈥損urpose 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鈥搗olatile
memory. When the chip is subsequently powered up in
operating mode these values are automatically restored
to the on鈥揷hip registers and the Input/Output pin
becomes the oscillator output.
The DS1075 is available in 8鈥損in DIP or SOIC pack-
ages, allowing the generation of a clock signal easily,
economically and using minimal board area.
