Programmable silicon oscillator for clock generation
The Analog Devices LTC6904CMS8#PBF is a programmable silicon oscillator that generates a square-wave clock output from 1 kHz to 68 MHz without requiring a crystal, ceramic resonator, or external timing components. The frequency is set via a 3-wire SPI-compatible serial interface, allowing in-circuit adjustment without component swaps.
