What this silicon oscillator does for your clock tree
The LTC6908IS6-2#TRPBF is a programmable silicon oscillator from Analog Devices that generates a square-wave clock from 50 kHz to 10 MHz without an external crystal or resonator.
Frequency programming and supply margin
The output frequency is set by a single external resistor — no crystal, no ceramic resonator, no external load capacitors. The range spans 50 kHz to 10 MHz, covering most MCU clock, data converter, and serial-interface timing needs. The supply current of 1.25 mA is a typical value — at the low end of the frequency range it drops further, making this a candidate for always-on clock domains in portable gear.
