DESCRIPTION
The DS1075 Custom is a fixed frequency oscillator requiring no external components for operation.
Numerous operating frequencies are possible in the range 29.2 kHz to 100 MHz through the use of an on-
chip factory-programmable prescaler and divider.
The DS1075 Custom is shipped from the factory pre-programmed on a custom basis to the customers
specified output frequency and mode of operation. The part is branded according to the device鈥檚 master
frequency (see DS1075 data sheet). The customer fills out a 鈥?075 Custom Order Form鈥?with the
required information and submits it to the factory for approval.
Custom EconOscillators are available in two versions, Simple Custom and Complex Custom, that can be
programmed at the factory in sample and volume quantities.
Simple Custom parts are based on one of the standard master frequencies of 60, 66, 80 and 100 MHz with
non-standard values programmed for the dividers and function select bits. An impressive number (over
1500) of sub-frequencies can be programmed using a Simple Custom part.
Complex Custom parts have a non-standard Master frequency (within the 60 MHz to 110 MHz range)
programmed into the internal master oscillator and non-standard values are programmed for the dividers
and function select bits. Virtually any frequency within the 29.24 kHz to 110 MHz range is possible
using complex custom parts Contact the factory for Custom Part selection and ordering information.
The DS1075 Custom is available in 8-pin DIP or SOIC packages, allowing the generation of a clock
signal easily, economically and using minimal board area.
