3.5795 MHz MEMS oscillator with AEC-Q100 qualification
The DSC1001CI2-003.5795T is a Microchip MEMS-based XO (Standard) oscillator delivering a 3.5795 MHz CMOS output from a 4-SMD, no-lead package. It operates across a 1.8V to 3.3V supply range and draws a maximum of 6.3 mA from the rail when active. AEC-Q100 qualification means this part has passed the automotive-grade reliability stress tests — temperature cycling, ESD, and latch-up — making it suitable for under-hood or cabin electronics where a standard commercial oscillator might drift or fail. The standby (power-down) function drops supply current to 15 µA max, letting the oscillator hold its state while the rest of the module sleeps — a common requirement in automotive body controllers and sensor nodes that wake on a bus message.
Frequency stability and temperature range
For a 3.5795 MHz clock, that translates to a maximum frequency error of roughly ±89 Hz — tight enough to keep a CAN bus or UART link within its bit-rate tolerance without re-synchronisation.
It is available for both new designs and production replenishment through independent distribution, quoted to order against the BOM quantity.
