DESCRIPTION
The DS1065 is a fixed frequency oscillator requiring no
external components for operation. Numerous operat-
ing frequencies are possible in the range 30 kHz to 100
MHz through the use of an on–chip programmable pres-
caler and divider.
The DS1065 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 nonvola-
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 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. Pre–pro-
grammed devices can be ordered on a custom basis as
DS1065C–xxx.
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, econom-
ically and using minimal board area.
