The DSC1033BI2-017.7344T is a MEMS-based XO (standard oscillator) from Microchip's PureSilicon™ series, delivering a 17.7344 MHz CMOS output with ±25 ppm frequency stability across the full industrial temperature range.
This is the kind of feature that matters in a remote sensor node or a handheld device that sleeps between reads.
Listed as Active by Microchip.
Yes — the Standby (Power Down) function is built in. When enabled, the supply current drops to 1 µA max, making it suitable for battery-powered or intermittently operating systems.
CMOS output — it drives standard digital logic inputs directly without external level translation.
The evidence does not list a RoHS compliance statement. Confirm with the datasheet or request a RoHS certificate of compliance at RFQ time.
