MEMS oscillator with standby — 1 MHz, CMOS, 3.3 V
The DSC1033AI1-001.0000 is a 1 MHz MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a CMOS output from a 3.3 V supply rail.
Power budget and board-fit details
Active current is 3 mA typical — low enough that the oscillator's draw won't dominate a sensor node's sleep-cycle budget, especially when the standby pin cuts it to microamps. The 4-SMD, no-lead exposed-pad package (7.00 mm × 5.00 mm, 0.90 mm seated height) is hand-solderable with a fine-tip iron or hot-air station; the exposed pad helps thermal coupling to the board ground plane.
Listed as Active — no NRND or EOL flags.
