Product details

Why choose a MEMS oscillator over a quartz crystal for this 25 MHz clock?

It delivers a 25 MHz CMOS output from a 1.8V to 3.3V supply rail, drawing a maximum of 6.3 mA during active operation and only 15 µA in standby (power-down) mode — the standby current is low enough for battery-backed RTC or wake-up circuits that must preserve charge over long idle periods.

Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the DSC1001BI1-025.0000 fits the standard 5.0 x 3.2 mm oscillator footprint common in automotive and industrial PCBs. The no-lead construction reduces parasitic inductance compared to a gull-wing package, which helps maintain signal integrity at 25 MHz.

Frequently asked questions

Can DSC1001BI1-025.0000 replace a standard 25 MHz quartz crystal oscillator?

Yes, it is a drop-in replacement for a 25 MHz CMOS quartz oscillator in the same 5.0 x 3.2 mm 4-pin footprint, provided the supply voltage (1.8V to 3.3V) and load capacitance are compatible. The MEMS construction offers better shock tolerance and faster startup than quartz, but the electrical interface is identical.

What is the standby current of DSC1001BI1-025.0000?

The maximum supply current in standby (power-down) mode is 15 µA. This is the current drawn when the output is disabled via the standby pin, making it suitable for battery-powered systems that need to preserve charge during idle periods.
