Product details

Why a MEMS oscillator instead of quartz

For a 32.768 MHz clock in an automotive or industrial environment, the MEMS construction eliminates the quartz aging drift that can pull a crystal oscillator outside the ±50 ppm stability window over ten years.

The 4-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — it is a standard 3.2 x 2.5 mm footprint that matches many quartz oscillators, so a board designed for a quartz XO in that size can accept the DSC1001 without a layout change. The surface-mount pads are on the bottom; no through-holes are needed.

Frequently asked questions

Is the DSC1001CI1-032.7680 compatible with a 1.8 V supply?

Yes. The supply voltage range is 1.8 V to 3.3 V, so it operates directly from a 1.8 V rail without an external regulator. The CMOS output swings rail-to-rail at any voltage in that range.

What is the standby power consumption of the DSC1001CI1-032.7680?

When the standby (power-down) function is asserted, the supply current drops to 15 µA maximum. In normal operation the maximum supply current is 7.2 mA.

Can the DSC1001CI1-032.7680 replace a failed quartz oscillator in an existing design?

If the original oscillator is a 32.768 MHz CMOS-output XO in a 3.2 mm x 2.5 mm 4-pin SMD package with a 1.8 V–3.3 V supply, the DSC1001CI1-032.7680 is a direct form-fit-function replacement. The MEMS resonator has different jitter characteristics than quartz, but the ±50 ppm stability and CMOS output are electrically compatible. Confirm the original part's frequency stability and temperature range match before substituting.
