270 kHz MEMS oscillator with AEC-Q100 qualification
The DSC6001JL1B-270K000 is a MEMS-based XO (Standard) delivering a fixed 270 kHz CMOS output — a frequency well suited for low-speed timing tasks like UART baud-rate generation, low-frequency PWM, or watchdog clocking in automotive and industrial systems. Rated for -40 to 105 °C and AEC-Q100 qualified, this oscillator can be placed in an under-hood ECU or cabin domain controller without a separate temperature derating review. Supply voltage spans 1.8 V to 3.3 V, so it works across common digital rails without a level translator on the output.
Frequency stability and supply current at 270 kHz
Frequency stability is ±50 ppm over the full temperature and voltage range — tight enough for most asynchronous serial links and general-purpose clocking, though not intended for precision timekeeping or RF reference. Maximum supply current is 1.3 mA typical — at 270 kHz the dynamic current is negligible, so the 1.3 mA figure is essentially the quiescent draw of the internal PLL and output buffer.
4-VLGA footprint and Enable/Disable function
Housed in a 4-VLGA package measuring 2.50 mm × 2.00 mm with a seated height of 0.89 mm — a compact footprint that suits space-constrained automotive ECU layouts. The Enable/Disable pin lets the system shut down the oscillator output for power savings; when disabled the output goes high-impedance, so a pull-up or pull-down on the clock line may be needed to prevent a floating input on the downstream device.
