The DSC1001CI2-003.5700T is a Microchip MEMS-based XO (standard oscillator) delivering a fixed 3.57 MHz CMOS output. It is built on a silicon MEMS resonator rather than a quartz crystal, which gives it better shock and vibration tolerance — relevant for automotive and industrial environments where a crystal might fracture or drift. The 4-VDFN package (3.20 mm x 2.50 mm) is a surface-mount footprint common for small oscillators; board layout should follow the manufacturer's recommended land pattern to avoid parasitic coupling on the output trace. Supply voltage range is 1.8V to 3.3V, so it can run off a 1.8V core rail or a 3.3V I/O rail without an extra regulator — useful when the same oscillator feeds both a low-voltage MCU and a 3.3V peripheral.
AEC-Q100 qualification and temperature grade
Rated AEC-Q100, this oscillator is qualified for automotive stress conditions including extended temperature cycling and ESD robustness. Frequency stability is ±25 ppm across the full temperature range — tight enough for CAN, LIN, and UART clocking without external trimming. For a 3.57 MHz bus, this translates to roughly ±89 Hz of drift worst-case, well within the tolerance of most MCU PLLs.
Power consumption and standby mode
Maximum supply current is 6.3 mA when active — low enough for battery-backed modules but not ultra-low-power. The standby (power-down) function drops draw to 15 µA max via the enable pin, which lets a system-level power controller gate the clock to save energy during sleep.
Lifecycle and ordering posture
Product status is Active — no end-of-life notice, no last-time-buy pressure. This part is suitable for both new designs and ongoing production. Sourced through independent distribution; quoted to order against the BOM quantity. Supplied on tape and reel (TR) for automated pick-and-place. The base product number is DSC1001; confirm the full suffix (CI2-003.5700T) matches your frequency and stability requirements.
