DS1085Z-10+

The DS1085Z-10+ is an EconOscillator frequency synthesizer in 8 pin NSOIC package. It is dual output frequency synthesizer requiring no external timing components for operation. It can be used as a standalone oscillator or as a dynamically programmed, processor controlled peripheral device. An internal master oscillator can be programmed from 66MHz to 133MHz with resolution of 10KHz. A programmable, 3bit prescaler (divide-by-1, 2, 4 or 8) permit the generation of a reference oscillator output (OUT0) from the master ranging from 8.2MHz to 133MHz. A second independent prescaler and a 1 to 1025 divider allow the generation of a main oscillator output (OUT1) from 8.1KHz to 133MHz. The two outputs, although synchronous with the master, can be independently programmed. The combination of programmable master oscillator, prescalers and dividers allows the generation of thousands of user-specified frequencies.
