Operating from a 1.8V to 3.3V supply rail, the part draws 6.3 mA maximum while oscillating and drops to 15 µA in Standby (Power Down) mode — a sleep-current floor that won't burden a battery-backed ECU module.
For a 1.8432 MHz clock driving a UART or LIN transceiver, this margin keeps the bit-rate error well below 2% even at the temperature extremes — no external trimming needed.
It is a Microchip DSC1001 series MEMS XO (Standard) with a 1.8432 MHz output in CMOS logic. Frequency stability is ±25 ppm, supply range is 1.8V–3.3V, and maximum supply current is 6.3 mA (15 µA in Standby mode). Package is a 4-SMD, no-lead 5.0×3.2 mm footprint. AEC-Q100 qualified.
Yes, the part is rated AEC-Q100, which means it has passed the automotive-grade stress tests for temperature, ESD, and reliability. This qualifies it for use in automotive electronic systems such as engine control modules, body controllers, and infotainment clusters.
Yes, the Standby (Power Down) function reduces the supply current to a maximum of 15 µA. When enabled, the output is disabled and the oscillator core is powered down, preserving battery or ignition-off supply in automotive modules.
The DSC1001 series provides ±25 ppm frequency stability, while the DSC1002 series offers tighter ±10 ppm stability. For a 1.8432 MHz clock driving a UART or LIN bus, ±25 ppm is typically sufficient; the DSC1002 would be chosen if the application requires tighter timing margin, such as for a high-speed CAN FD node with a wider temperature range.
