It generates a square-wave clock output from 1 kHz up to 20 MHz, set by a single external resistor — no external timing capacitor needed. The part runs from a 2.7 V to 5.5 V supply rail, drawing 920 µA typical, making it a drop-in for both 3.3 V and 5 V digital systems. Housed in a TSOT-23-5 package, it fits tight board layouts where a crystal plus load caps won't. ## Supply range and current — sizing the rail The 2.7 V to 5.5 V supply covers the two most common logic rails without a secondary regulator. At 920 µA typical supply current, the LTC6900 adds negligible load to a 3.3 V LDO or a 5 V switching regulator — useful when budgeting power for a sensor node or a control board that already runs hot. The wide supply tolerance also means the oscillator keeps running through a 5 V rail drooping to 3.3 V during a brown-out event, as long as the downstream logic can tolerate the frequency shift. ## Temperature range and environment Rated for -40°C to 85°C operation, this part covers the industrial temperature band. It suits outdoor telecom cabinets, factory-floor controllers, and automotive cabin-zone electronics (non-engine bay). No extended temp or AEC-Q100 grade here — if you need -40°C to 125°C, look at the LTC6908HS6-1#TRMPBF sibling. ## Package and footprint — board fit The TSOT-23-5 footprint is a standard 5-pin SOT-23 thin outline. It shares the same land pattern as many other silicon oscillators and temperature sensors, so swapping in a different vendor's part during a redesign may keep the PCB layout. The Tape & Reel (TR) or Cut Tape (CT) option lets you order production reels or small quantities for prototyping without changing the BOM line. ## Active status — no LTB surprise ADI lists the LTC6900CS5#TRMPBF as Active and ROHS3 compliant. No last-time-buy notice, no end-of-life window to track. You can qualify it into a new production BOM without worrying about a forced redesign in the next two years. For dual-source planning, the LTC6902CMS#TRPBF is a close functional peer — same 20 MHz ceiling, same 2.7 V min supply, same industrial temp range, in an MSOP-10 package (larger footprint). ## Sourcing this part If you need a reel of 500 or a cut-tape sample, the TR/CT packaging options are both orderable.","metaTitle":"LTC6900CS5#TRMPBF Silicon Oscillator, 1kHz–20MHz, TSOT-23-5","metaDescription":"LTC6900CS5#TRMPBF programmable silicon oscillator from Analog Devices.
