Product details

37.4 MHz MEMS XO with automotive-grade qualification

The MEMS resonator eliminates the quartz-crystal startup and aging drift concerns — the part is ready at power-on with no crystal-oscillator settling delay.

Standby function and supply current profile

This makes the DSC1001DC5-037.4000 a good fit for battery-backed or intermittent-duty systems where the clock can be gated off during sleep — the oscillator wakes and stabilises fast enough for the downstream logic to resume without a re-initialisation delay.

Package, supply range, and board-fit note

Housed in a 4-SMD no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm, the DSC1001DC5-037.4000 fits standard oscillator footprints. The supply voltage range of 1.8 V to 3.3 V covers common digital rails — no extra regulator needed when moving between 3.3 V and 1.8 V domains.

The base product number DSC1001 covers a range of frequencies and stability grades — if your BOM needs a different frequency, the same package and pinout are available within the series.

Frequently asked questions

Does the DSC1001DC5-037.4000 have a standby function?

Yes — the part includes a Standby (Power Down) function. When the standby pin is asserted, the oscillator stops and the supply current drops to 15 µA maximum, compared to 7.2 mA in active mode. This allows the clock to be gated off during system sleep without removing power from the oscillator.

Is the DSC1001DC5-037.4000 suitable for automotive applications?

Yes — it carries an AEC-Q100 rating, which qualifies it for automotive-grade reliability and temperature cycling.

What is the closest pin-compatible alternative within the DSC1001 series?

The DSC1001 series shares the same 4-SMD no-lead package and pinout across all frequency and stability options. If you need a different frequency or tighter stability, the base product number DSC1001 with the appropriate suffix is a direct drop-in replacement — no board layout change required.
