It delivers a 15.75 MHz CMOS output clock from a 1.8 V to 3.3 V supply rail, drawing 6.3 mA maximum. The 4-SMD, no-lead package (3.2 mm × 2.5 mm) places flat with good coplanarity; no tombstoning risk on a standard reflow profile.
Lifecycle status is Active — no EOL notice, no last-time-buy window.
This matters for battery-powered or intermittently-sleeping systems — the oscillator's own draw during sleep is below the leakage of most MCU I/O pins.
CMOS — standard 0-to-supply rail swing, compatible with most digital clock inputs on MCUs, FPGAs, and SoCs.
Yes, it carries an AEC-Q100 rating, meaning it passed automotive-grade reliability testing. However, the operating temperature range is -20°C to 70°C, so it is suited for cabin or climate-controlled automotive modules rather than under-hood locations.
±50 ppm over the operating temperature range and aging. For a 15.75 MHz clock, that translates to a maximum frequency error of ±787.5 Hz — tight enough for UART bit-rate timing and most microcontroller clock inputs.
