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 sub multiples of the
matter frequency through the use of two on-chip programmable prescalers and a divider. The specific
output frequencies chosen are stored in non-volatile (EEPROM) memory. The DS1077 defaults to these
values on powerup.
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 non-volatile
(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, SOIC or uSOP packages, allowing the generation of a clock signal
easily, economically and using minimal board area. Chip scale packaging is also available on request.
