Product details

3.5795 MHz MEMS oscillator with AEC-Q100 qualification

The DSC1001CI2-003.5795T is a Microchip MEMS-based XO (Standard) oscillator delivering a 3.5795 MHz CMOS output from a 4-SMD, no-lead package. It operates across a 1.8V to 3.3V supply range and draws a maximum of 6.3 mA from the rail when active. AEC-Q100 qualification means this part has passed the automotive-grade reliability stress tests — temperature cycling, ESD, and latch-up — making it suitable for under-hood or cabin electronics where a standard commercial oscillator might drift or fail. The standby (power-down) function drops supply current to 15 µA max, letting the oscillator hold its state while the rest of the module sleeps — a common requirement in automotive body controllers and sensor nodes that wake on a bus message.

Frequency stability and temperature range

For a 3.5795 MHz clock, that translates to a maximum frequency error of roughly ±89 Hz — tight enough to keep a CAN bus or UART link within its bit-rate tolerance without re-synchronisation.

It is available for both new designs and production replenishment through independent distribution, quoted to order against the BOM quantity.

Frequently asked questions

Is the DSC1001CI2-003.5795T drop-in compatible with standard 3.5795 MHz quartz oscillators?

Yes, in most cases. The DSC1001CI2-003.5795T is a MEMS oscillator in a standard 4-SMD, no-lead footprint (3.20mm x 2.50mm) with CMOS output — the same pinout and output type as a quartz XO. No external load capacitors are needed; the MEMS resonator is self-contained. Verify the supply voltage range (1.8V to 3.3V) matches your existing rail, and confirm the enable/standby pin logic if your board uses that feature.

What is the standby current consumption of the DSC1001CI2-003.5795T?

When the standby (power-down) function is active, the supply current drops to 15 µA maximum. This is the current drawn from the Vdd rail while the output is disabled, allowing the oscillator to remain connected without draining the battery in a sleep-mode application.
