The DS1077L is a dual-output, programmable, fixed-frequency oscillator requiring no external
components for operation. The DS1077L can be used as a processor-controlled frequency synthesizer or
as a stand-alone 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
dividers. The specific output frequencies chosen are stored in nonvolatile (EEPROM) memory. The
DS1077L defaults to these values upon power-up.
The DS1077L 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 nonvolatile
(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. Preprogrammed devices can be ordered in customer-requested frequencies.
The DS1077L is available in SO or µSOP packages, allowing the generation of a clock signal easily,
economically, and using minimal board area. Chip-scale packaging is also available on request.
