AEC-Q100 qualified 26 MHz MEMS oscillator — what it buys the design
The DSC1001CI2-026.0000T is an AEC-Q100-qualified MEMS-based XO delivering a fixed 26 MHz output with CMOS drive. The qualification means this part has passed the full automotive stress suite — temperature cycling, ESD, latch-up, and early-life failure rate — and carries PPAP documentation the OEM auditor will require.
Supply voltage flexibility and standby power
The wide supply range of 1.8V to 3.3V lets the oscillator run directly from the same rail as the MCU or transceiver, eliminating a dedicated LDO for the clock source. In standby (power-down) mode, the oscillator draws a maximum of 15 µA — low enough that a battery-backed RTC or wake-up circuit can keep the clock domain alive for months on a coin cell. Active supply current is 6.3 mA max at full speed, a typical figure for a MEMS oscillator at this frequency.
Package, footprint, and assembly
Housed in a 4-SMD no-lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm, the DSC1001CI2-026.0000T fits standard 4-pad oscillator footprints and reflow profiles. Available in both tape-and-reel and cut-tape formats, it is compatible with high-volume pick-and-place assembly.
The DSC1001 series is a current production family, suitable for both new designs and ongoing production.
