MEMS resonator — ±10 ppm stability across industrial temperatures
The DSC1121BI5-024.5760: A MEMS base resonator replaces the quartz crystal found in conventional XOs. For a 24.576 MHz clock feeding an Ethernet PHY or a USB controller, that stability keeps the link margin intact without a separate temperature-compensation circuit.
Housed in a 6-VDFN package measuring 0.197" × 0.126" (5.00 mm × 3.20 mm) with a seated height of 0.035" (0.90 mm). No exposed pad — the package outline matches the common 5.0 × 3.2 mm oscillator land pattern used across the DSC1121 series.
