Silicon oscillator — no crystal matching needed
The LTC6930HDCB-8.00#TRMPBF is a silicon oscillator from Analog Devices that generates a fixed 8 MHz clock without any external crystal, load capacitors, or feedback resistors. This eliminates the most common failure point in crystal-based designs: a mismatched load capacitance that prevents startup or causes frequency drift over temperature. It operates from a single 1.7V to 5.5V supply, so it can be powered directly from a Li-ion cell, a 3.3V rail, or a 5V bus without an intermediate regulator. The supply current is 926 µA typical at 8 MHz, which keeps the thermal rise low in the compact 8-DFN (2x3 mm) package and extends battery life in portable instruments.
Active production — no EOL concern
It is ROHS3 compliant, so it meets the latest EU restriction requirements for lead and other substances. The part is supplied on Tape & Reel (TR) and also available as Cut Tape (CT) for prototype or low-volume builds. The 8-DFN (2x3 mm) footprint is a standard 8-lead WFDFN with an exposed pad — confirm the land pattern matches your PCB layout before committing the BOM line.
