What this 54 MHz MEMS oscillator brings to the board
The DSC1001AI2-054.0000 is a 54 MHz MEMS-based XO (Standard) with a CMOS output — it replaces a quartz crystal plus load capacitors with a single silicon resonator that does not require external tuning components. Its supply voltage range of 1.8V to 3.3V means it runs directly from a 1.8V, 2.5V, or 3.3V rail without a level translator — a single BOM line covers multiple logic families.
Automotive-grade qualification and deployment context
This oscillator carries AEC-Q100 qualification — it is rated for automotive stress and reliability, so it can be placed in under-hood or chassis-domain ECUs where a commercial-grade XO would not pass PPAP.
Power budget and standby behaviour
Maximum active supply current is 7.2 mA at 54 MHz — low enough that a 3.3V rail feeding this oscillator plus a small MCU stays within the budget of a linear regulator without a heatsink.
The 4-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint that matches many 7x5 mm XO land patterns, so a layout change from a quartz oscillator to this MEMS part is often a drop-in swap.
