48 MHz MEMS oscillator with AEC-Q100 grade
The DSC1001CC2-048.0000 is a 48 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output in a 4-SMD, no-lead package measuring 3.20mm x 2.50mm. Rated AEC-Q100, this oscillator is qualified for automotive applications — the MEMS resonator and CMOS output stage are screened to the reliability and temperature stress requirements of the automotive IC standard. The supply voltage range spans 1.8V to 3.3V, covering common digital rails without an external level translator — a single part serves 1.8V, 2.5V, or 3.3V logic domains.
Standby function and current draw
A standby (power-down) function disables the output and reduces supply current to 15 µA max — useful for battery-backed or sleep-mode applications where the clock tree is gated off. Active supply current is 7.2 mA max at 48 MHz, typical for a MEMS oscillator at this frequency — the CMOS output swings rail-to-rail, so the load capacitance on the clock trace directly affects the actual draw.
Temperature grade and deployment boundary
Frequency stability is ±25 ppm over the full temperature range — tight enough for a 48 MHz clock feeding an MCU or FPGA without additional PLL calibration.
