What this MEMS oscillator brings to a 54 MHz clock line
Supply voltage range and standby power
Supply voltage spans 2.25V to 3.6V, covering the common 2.5V and 3.3V logic rails without an external regulator — one less component on the BOM. When the standby (power-down) pin is asserted, the oscillator draws a maximum of 95 µA, which lets a battery-powered system keep the clock line alive during sleep without draining the cell. Active draw is 35 mA max at 54 MHz — typical for a MEMS oscillator at this frequency and within the budget of any 2.5V or 3.3V rail rated for a few hundred milliamps.
Package, footprint, and production status
Housed in a 6-SMD no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — a standard footprint that matches many 5.0 x 3.2 mm quartz oscillators, so a board designed for a quartz can often take this MEMS part without a layout change. No last-time-buy clock is ticking.
