The DSC1001CI2-001.9521 is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a fixed 1.9521 MHz CMOS output. The supply voltage range spans 1.8V to 3.3V, letting it run from a 1.8V core rail or a 3.3V I/O rail without an external regulator.
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm.
The output frequency is 1.9521 MHz, a CMOS-level clock signal. This is a fixed-frequency XO – no programmability or tuning range.
Yes, it carries an AEC-Q100 rating, which means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up.
Yes, it includes a Standby (Power Down) function. When enabled, the current draw drops to 15 µA max, versus 6.3 mA max during normal operation. This is useful for battery-powered systems that need to disable the clock during sleep modes.
