This Design Idea describes an inexpensive circuit to generate two extremely high-quality, crystal-clock-reference-signals, one of which is a PWM-controlled VCXO (voltage-controlled crystal oscillator) ...

Maxim Integrated Products has introduced low-power (less than 1.2microamps), microprocessor supervisory circuits that feature precision power-supply monitoring and battery-control functions.

Based on a patented digital timing technology, the TLC28x0 timing processor chip offers designers six independent high-resolution clock synthesizers—more than any other available clock synthesizer ...
