What this MEMS oscillator delivers on the board
The DSC1001AC5-012.8000 is a fixed-frequency 12.8 MHz MEMS oscillator from Microchip's DSC1001 series, delivering a CMOS output with ±10 ppm frequency stability across its 0°C to 70°C operating range. It runs from a 1.8V to 3.3V supply rail, drawing a maximum of 6.3 mA when active, and drops to 15 µA in standby (power-down) mode — useful for battery-powered designs that need to shut the clock tree when idle.
Automotive qualification and temperature grade — what fits where
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, this oscillator fits a standard 7x5 mm oscillator footprint — the same land pattern used by many quartz and MEMS oscillators in this form factor.
