FAQ
What is the nominal frequency and tolerance of the VXM7-9043-24M0000000?
The VXM7-9043-24M0000000 has a nominal frequency of 24.000 MHz with a frequency tolerance of ±10 ppm at 25 °C. This tolerance is measured under specified load conditions (18 pF) and remains within ±10 ppm across its full operating temperature range of 0–70 °C, making it suitable for USB 2.0 and industrial MCU clocking where tight timing budgets apply.
Does the VXM7-9043-24M0000000 require external load capacitors?
Yes, the VXM7-9043-24M0000000 is designed for use with a 18 pF load capacitance. External capacitors must be placed between each crystal terminal and ground in the oscillator circuit to meet this requirement. The exact values depend on PCB stray capacitance and oscillator IC specifications, typically requiring two identical capacitors in the 15–22 pF range.
What is the maximum drive level and ESR specification for the VXM7-9043-24M0000000?
The VXM7-9043-24M0000000 specifies a maximum drive level of 100 µW and a maximum equivalent series resistance (ESR) of 60 Ω. These parameters ensure reliable oscillation startup and sustained operation with standard CMOS oscillator circuits, while minimizing power consumption and thermal stress in battery-powered or thermally constrained applications.
Is the VXM7-9043-24M0000000 compatible with lead-free reflow processes?
Yes, the VXM7-9043-24M0000000 is fully compatible with lead-free reflow per JEDEC J-STD-020. It supports a peak temperature of 260 °C for up to 30 seconds, ramp-down ≤6 °C/sec, and time above 217 °C between 60–150 seconds. Its MSL 1 rating means no floor-life limitations or pre-baking is required before assembly.
How does aging affect long-term accuracy of the VXM7-9043-24M0000000?
The VXM7-9043-24M0000000 exhibits ±3 ppm aging over the first year at 25 °C. This drift is cumulative and predictable, enabling firmware compensation in high-accuracy applications like smart meters and industrial timers. Subsequent annual aging decreases significantly, supporting >10-year operational accuracy when combined with initial calibration.
