What this silicon oscillator does for your timing chain
The LTC6908HS6-1#TRMPBF is a silicon oscillator from Analog Devices that generates a square-wave clock from 50kHz up to 10MHz, set by a single external resistor — no crystal, no ceramic resonator, no external tuning components beyond that resistor. It runs on a 2.7V to 5.5V supply rail, which covers 3.3V and 5V logic domains without a separate regulator, and draws only 1.25 mA typical supply current — a low-power choice for battery-operated or thermally constrained boards.
The 2.7V minimum supply lets it run from a 3.3V rail with margin for brownout, while the 5.5V maximum accommodates a 5V rail with 10% tolerance — no extra LDO needed in most designs.
Lifecycle and sourcing — active production, no obsolescence risk
It is ROHS3 compliant and ships in Tape & Reel — the TRMPBF suffix indicates 7-inch reel, 500-piece quantity typical for this series.
Package and mounting — TSOT-23-6 footprint notes
The TSOT-23-6 package is a thin SOT-23 with 0.95 mm pitch typical — standard for small-signal ICs. The 6-pin layout includes the output, supply, ground, and a SET pin for the frequency-setting resistor. The small body (approx 2.9 mm x 1.6 mm) suits dense PCB layouts.
