This is not a standard commercial oscillator with an extended temp range sticker; the qualification program includes ESD, latch-up, and accelerated life testing that the quartz equivalent typically skips. Operating from -40°C to 105°C, it sits in the industrial-plus band that covers under-hood electronics, outdoor telecom enclosures, and factory-floor controllers. The 1.8V to 3.3V supply range means it can run directly off a 1.8V MCU rail or a 3.3V peripheral bus without an intermediate regulator.
Supply current and standby power — the numbers that matter for battery and always-on designs
That is low enough to leave the clock rail powered during a system sleep state without draining the backup battery; the wake-up time from standby is typically under 5 ms (MEMS start-up advantage over quartz).
Package footprint and mounting — what fits the board
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm max. This is the same footprint as many standard 25 MHz quartz oscillators (commonly 3.2 x 2.5 mm), so the DSC1001CL1 is a drop-in replacement for a quartz XO in that form factor — no board layout change needed.
No minimum order quantity constraints beyond the reel increment.
