Active silicon oscillator at 4.194304 MHz — BOM-fit for low-power timing
The LTC6930CMS8-4.19#PBF is an Analog Devices silicon oscillator delivering a fixed 4.194304 MHz output from a 1.7V to 5.5V supply while drawing only 490 µA typical.
Supply range and current — sizing for battery and low-dropout rails
The 1.7V to 5.5V supply range lets the oscillator run directly from a Li-ion cell or a 3.3V / 5.0V regulated rail without an extra LDO. At 490 µA supply current, the part adds negligible overhead to the system power budget — a meaningful advantage over a crystal-plus-inverter solution that can draw several milliamps.
Package and footprint — 8-MSOP for dense layouts
Surface-mount assembly with MSL (moisture sensitivity level) typical for this package class — no special bake required before reflow if the floor life is respected.
ROHS3 compliant.
