The DS1085 is a 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 three
resolution options of 10kHz, 25kHz, and 50kHz. A programmable, 3-bit prescaler (divide-by-1, 2, 4, or 8)
permits 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 allows 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. All master
oscillator, prescaler, and divider settings are stored in NV (EEPROM) memory, providing a default value
on power-up that allows it to be used as a standalone oscillator. A 2-wire serial interface allows in-circuit,
on-the-fly programming of the master oscillator, prescalers (P0 and P1), and divider (N). This allows
dynamic frequency modification, if required, or, for fixed-frequency applications, the DS1085 can be
used with factory- or user-programmed values.
