DESCRIPTION
The DS1077 is a dual-output, programmable, fixed-frequency oscillator requiring no external
components for operation. The DS1077 can be used as a processor-controlled frequency synthesizer or
as a standalone oscillator. The two synchronous output operating frequencies are user-adjustable in
submultiples of the master frequency through the use of two on-chip programmable prescalers and a
divider. The specific output frequencies chosen are stored in NV (EEPROM) memory. The DS1077
defaults to these values upon power-up.
The DS1077 features a 2-wire serial interface that allows in-circuit on-the-fly programming of the
programmable prescalers (P0 & P1) and divider (N) with the desired values being stored in NV
(EEPROM) memory. Design changes can be accommodated in-circuit on-the-fly by simply
programming different values into the device (or reprogramming previously programmed devices).
Alternatively, for fixed frequency applications, previously programmed devices can be used and no
connection to the serial interface is required. Pre-programmed devices can be ordered in customer-
requested frequencies.
The DS1077 is available in 8-pin SO or SOP packages, allowing the generation of a clock signal
easily, economically, and using minimal board area. Chip-scale packaging is also available on request.
