54 MHz fixed-frequency MEMS oscillator — what it replaces
Output is CMOS, 3.3V supply rail. No programmability: the frequency is laser-trimmed at the factory to 54 MHz and locked. The package is a 4-SMD no-lead with an exposed pad (7.00 mm × 5.00 mm, seated height 0.90 mm). Standard reflow profile for a 4-layer board with via-in-pad under the pad is fine; the MEMS die is not moisture-sensitive beyond MSL 1 typical for this class.
Industrial temperature range and ±25 ppm stability
Active current draw is 4 mA typical at 54 MHz into a CMOS load. Standby (power-down) mode drops to 1 µA max via the Standby pin — useful for battery-powered designs that sleep the oscillator between wake events. The disable pin is active-low; leave it pulled high or tied to Vdd if not used.
This is a current, design-in-capable part. Confirm the full order code matches your BOM — a different suffix changes voltage, stability, or temp range.
