50 MHz MEMS oscillator with AEC-Q100 grade
Rated AEC-Q100, this oscillator is qualified for automotive-grade applications — the under-hood or chassis-domain temperature band — where a quartz crystal might drift beyond the ppm budget under vibration or thermal shock.
Supply voltage range and standby power-down
Operates from a 1.8V to 3.3V supply rail, covering the common digital core and I/O voltages used in automotive ECUs and industrial controllers without requiring a separate regulator for the oscillator. The standby (power-down) function drops the supply current to 15 µA max when the enable pin is pulled low — a sleep-mode current low enough that a battery-backed RTC or CAN transceiver can leave the oscillator powered without draining the reserve cell. Active current draw is 7.2 mA max at 50 MHz, which is typical for a MEMS oscillator at this frequency and well within the output drive capability of a 3.3V LDO.
Package footprint and mounting
Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2 x 2.5 mm land pattern that matches many quartz oscillator footprints, simplifying a drop-in replacement. Surface-mount assembly; the no-lead construction means the solder joint is under the package body, so the PCB pad design must include a thermal relief and a solder mask dam to prevent bridging.
The DSC1001 series is an ongoing Microchip product line, so new designs can commit to this order code without a near-term obsolescence risk. Sourced through independent distribution; quoted to order against the BOM quantity.
