MEMS resonator replaces quartz — what that means for your board
The DSC1001CI1-032.0000: This is a MEMS-based XO (Standard) oscillator, not a quartz crystal — the base resonator is a silicon MEMS structure rather than a quartz blank. The 32 MHz CMOS output clocks microcontrollers, FPGAs, or Ethernet PHYs without an external load capacitor pair. The MEMS construction gives better shock and vibration tolerance than a quartz fundamental-mode crystal, and the startup time is typically under 5 ms — no crystal oscillation build-up delay. Supply voltage spans 1.7V to 3.6V, so the same oscillator works on a 1.8V, 2.5V, or 3.3V rail without a separate level shifter. Maximum active current is 10.5 mA; standby (power-down) mode drops supply current to 15 µA — useful for battery-powered modules that sleep between transmissions.
Automotive-grade qualification and temperature range
Rated AEC-Q100, the part is qualified for automotive stress conditions — temperature cycling, ESD, and latch-up per the automotive IC reliability standard. Frequency stability is ±50 ppm across the full temperature range — tight enough for a 32 MHz MCU clock or a CAN/Ethernet reference without external trimming. The 4-VDFN package (3.20 mm x 2.50 mm footprint, 0.90 mm seated height) fits compact automotive ECUs and portable devices.
