MEMS resonator replaces the quartz crystal
The DSC1502AI3A-8M000000 uses a MEMS base resonator instead of a quartz crystal, which means better shock and vibration immunity than a traditional quartz oscillator — relevant for industrial and automotive environments where mechanical stress can shift the frequency of a quartz blank. It is an 8 MHz fixed-frequency oscillator with LVCMOS output, suited as a system clock for an MCU, FPGA, or Ethernet PHY that expects a 3.3V or 2.5V CMOS-level square wave.
±20 ppm stability over -40 to 85°C
The 2.5V to 3.3V supply range lets it run from either a 3.3V or 2.5V rail without an intermediate LDO; the 7.5 mA max supply current is low enough to run from a GPIO-powered rail on a battery-operated board.
Standby function and disable current
A standby (power-down) pin cuts the oscillator output and drops the supply current to 1.8 µA typical — useful for battery-powered designs that can gate the system clock to save power in sleep modes.
Product status is Active — no last-time-buy notice, no end-of-life clock. The part is available for new designs and volume production.
