The DSC1001AE1-066.6660 is a 66.666 MHz XO (Standard) oscillator from Microchip Technology's DSC1001 series, built on a MEMS resonator with CMOS output. It delivers a fixed-frequency clock source rated for automotive environments per AEC-Q100. Supply voltage spans 1.8 V to 3.3 V, making it compatible with both 1.8 V and 3.3 V logic domains without an external level translator.
7.2 mA active, 15 µA standby — power budget fit
Maximum supply current during oscillation is 7.2 mA, while the standby (power-down) mode draws only 15 µA — the standby current is two orders of magnitude lower than the active draw, enabling battery-powered or sleep-mode designs to conserve energy. The standby function disables the output and stops the oscillator, reducing power to the 15 µA level.
Active lifecycle — no LTB or obsolescence watch
4-SMD, no-lead exposed pad — layout note
Housed in a 7.00 mm × 5.00 mm 4-SMD package with an exposed pad (no lead). Height seated is 0.90 mm max, fitting within standard 1.0 mm clearance profiles on dense PCBs. The surface-mount package is compatible with reflow soldering; MSL level should be confirmed from the Microchip packaging label.
