Silicon Oscillators
Analog Devices silicon oscillators are frequency programmable via pin-strapping, or through the resistor connection or serial interface (SPI or I2C). These solid-state clocks are well-suited for general-purpose usage, such as PGAs, ASICS, microprocessors, or UARTS, and they operate from 1 kHz to 170 MHz. Silicon oscillators are also ideal switching regulator clocks as they provide synchronization and EMI reduction (via spread spectrum).
