DESCRIPTION
The DS1085L 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 33MHz to 66MHz with three
resolution options of 5kHz, 12.5kHz, and 25kHz. 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 4.13MHz to
66MHz. A second independent prescaler and a 1-to-1025 divider allow the generation of a main oscillator
output (OUT1) from 4.1kHz to 66MHz. 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 DS1085L can be used with factory- or
user-programmed values.
