Product details

The DSC1001CI5-054.0000T is a 54 MHz MEMS-based XO from Microchip's DSC1001 series, outputting a CMOS-level clock from a 1.8V to 3.3V supply rail.

AEC-Q100 and the reflow decision

For the contract manufacturer, that also means the part ships with a defined MSL — check the reel label before the oven; a bake step is required if the floor life is exceeded. The 4-SMD no-lead package (3.20 mm × 2.50 mm, 0.90 mm seated height) is a standard footprint shared across the DSC1001 family.

Standby current and power-down gating

The enable pin is active-low; leave it floating or tied to ground to keep the oscillator running.

Frequently asked questions

Is the DSC1001CI5-054.0000T AEC-Q100 qualified?

Yes, the part carries an AEC-Q100 rating, meaning it passed the automotive IC qualification suite: temperature cycling, biased humidity, ESD, and latch-up.

What is the standby current of the DSC1001CI5-054.0000T?

The standby (power-down) supply current is 15 µA max. When the enable pin is asserted, the oscillator stops and the output goes high-impedance, leaving only the bias circuitry drawing current.

Can the DSC1001CI5-054.0000T replace a standard 54 MHz crystal oscillator?

Yes, it is a drop-in replacement for a 54 MHz CMOS-output XO in the same 4-SMD footprint. The MEMS resonator gives better shock and vibration tolerance than a quartz crystal — useful if the board is headed into an automotive or industrial environment where mechanical stress is a concern.
