64.8 MHz MEMS clock for automotive and industrial boards
The DSC1001CE1-064.8000T is a 64.8 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output across a 1.8V–3.3V supply range. The MEMS resonator replaces a quartz crystal, giving it better shock and vibration tolerance than a traditional crystal oscillator — useful for engine-bay or factory-floor environments where the board sees mechanical stress. Rated AEC-Q100, this part is qualified for automotive temperature and reliability stress. The -20°C to +70°C operating range covers cabin and most under-hood ambient conditions. Frequency stability is ±50 ppm over the full temperature range, which is adequate for general-purpose clocking of MCUs, CAN transceivers, and Ethernet PHYs that do not require a TCXO or OCXO. The standby (power-down) function drops supply current to 15 µA max, letting the system shut the oscillator off during sleep modes without a separate load switch.
Sourcing and lifecycle — active, quoted to order
Supplied in Tape & Reel (TR) packaging. The 3.20 mm x 2.50 mm footprint is common among MEMS oscillators in this frequency range, so the PCB land pattern is interchangeable with many other 4-pin SMD oscillators — useful if a second-source qualification is needed later.
Package and board-fit checklist
Package: 3.20 mm x 2.50 mm, seated height 0.90 mm max. Confirm the pad layout matches the recommended land pattern in the datasheet; the 0.90 mm height clears most conformal-coat thicknesses. Supply voltage range 1.8V–3.3V covers the common digital rails. The CMOS output swings rail-to-rail, so no level translation is needed when feeding a 1.8V or 3.3V logic input. Maximum supply current is 7.2 mA at full load; the standby current of 15 µA max lets the oscillator share a lightly loaded power rail without a dedicated enable pin.
