Product details

The DSC1001CE1-019.6608 is a 19.6608 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output across a 1.8V to 3.3V supply range.

Supply voltage and output compatibility

Operating from 1.8V to 3.3V, the oscillator can be powered directly from a 1.8V core rail, a 2.5V I/O rail, or a 3.3V peripheral bus — no external level translation needed on the supply side. The CMOS output drives standard logic families (LVCMOS, LVTTL) and is compatible with most MCU, FPGA, and SoC clock inputs without additional buffering.

Package, footprint, and mounting

Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm (0.126" x 0.098") with a seated height of 0.90 mm max — a standard 3.2 x 2.5 mm ceramic oscillator footprint. Surface-mount assembly with the four pads on the bottom: supply, ground, output, and enable/standby. The no-lead construction keeps the parasitic inductance low for clean clock edges.

Frequently asked questions

Is DSC1001CE1-019.6608 an automotive-grade oscillator?

Yes, it is AEC-Q100 qualified, meaning it has passed the automotive reliability stress tests for temperature, humidity, and operating life. However, its -20°C to 70°C temperature range is narrower than the full automotive ambient range — verify the application's thermal requirements.

Does DSC1001CE1-019.6608 have a standby function?

Yes, it includes a standby (power-down) function that reduces supply current to 15 µA max when disabled, allowing the clock tree to be gated off in low-power modes.
