66.6667 MHz MEMS clock source for industrial timing
The DSC1505AI3A-66M66670: Unlike a quartz crystal oscillator, the MEMS resonator is inherently more resistant to vibration and mechanical shock — a real advantage in motor-drive or outdoor telecom enclosures where board flex and thermal cycling can pull a quartz fundamental off frequency.
Standby power-down and supply rail
Runs from a single 1.8V supply rail, drawing 7.5 mA max in active mode. The standby (power-down) function drops the current draw to 1 µA typical — useful for battery-backed systems that need to disable the clock between active intervals without removing power.
Package and board-fit note
Housed in a 4-VDFN with exposed pad, 7.00 mm x 5.00 mm footprint, seated height 0.90 mm max.
