MEMS oscillator replaces quartz at 18.432 MHz
The DSC1001BL5-018.4320T: This is a MEMS-based XO (Standard) oscillator, not a quartz crystal — it generates a fixed 18.432 MHz clock from a silicon resonator, which means it resists vibration-induced frequency shifts better than a quartz part in the same footprint. Output is CMOS, so it drives logic inputs directly without external termination or level translation for most 1.8V to 3.3V rails.
Automotive-grade timing for harsh environments
Frequency stability is held to ±10 ppm across temperature, which keeps CAN, LIN, or Ethernet PHY clocking within the jitter budget without an external PLL cleanup.
Standby function cuts power to 15 µA
A standby (power-down) pin disables the output and drops supply current from 6.3 mA max to 15 µA max — useful for battery-backed modules that need to hold the clock tree off during sleep.
