The DSC1122AI5-025.0020: The MEMS resonator replaces a quartz crystal, giving the oscillator better shock and vibration immunity while eliminating quartz-specific lead-time variability — a sourcing advantage during allocation cycles. The Enable/Disable function lets the output be tri-stated for power savings or test modes, drawing 22 mA max in the disabled state versus 58 mA max when active.
The MEMS resonator gives it better resistance to shock and vibration compared to quartz, and MEMS oscillators typically have shorter manufacturing lead times — a key consideration during allocation periods. The electrical performance (frequency stability, jitter) is comparable to quartz XOs in the same stability grade.
