40.608 MHz MEMS clock for automotive and industrial timing
The DSC1001AE2-040.6080T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 40.608 MHz CMOS output with ±25 ppm frequency stability across its -20°C to 70°C operating range. AEC-Q100 qualification means this oscillator has passed automotive-grade reliability stress tests, making it suitable for cabin and chassis-domain electronics where temperature cycling and vibration are routine. The MEMS resonator replaces a quartz crystal, offering better shock and vibration immunity — a practical advantage in automotive and industrial environments where quartz crystals can fracture under sustained mechanical stress.
Supply range and standby power discipline
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. The 7.2 mA max supply current is typical for a MEMS oscillator at this frequency — no surprise for the power budget. A standby (power-down) function drops the supply current to 15 µA max when the output is disabled. This matters for battery-backed modules that must preserve the clock source but stop toggling during sleep — the disable current is low enough to ignore in a typical automotive sleep budget.
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The exposed pad on the underside aids thermal conduction to the PCB — ensure the pad is soldered to a ground plane for best thermal and mechanical performance. Supplied on Tape & Reel (TR), compatible with standard pick-and-place assembly. The surface-mount footprint matches common 7x5 mm oscillator pads — no special layout beyond the pad pattern.
