MEMS oscillator vs quartz — why this part exists
The MEMS resonator is sealed at the die level, so there is no load-capacitance matching to get wrong — a common failure point with quartz oscillators where the wrong CL or excessive drive level causes startup failures or frequency drift.
Frequency stability and temperature grade
For a 24.576 MHz clock feeding a USB or Ethernet PHY, that tight stability keeps the bit-rate within the receiver's ppm budget without a separate TCXO. The operating temperature band covers outdoor telecom enclosures, factory-floor controllers, and automotive cabin modules.
The supply voltage range spans 1.8V to 3.3V, so the same part can be used across 1.8V-core and 3.3V-I/O domains without a separate level translator on the clock line.
