Frequently Asked Questions
Why is a 48 MHz crystal like JA-48.000-8-EHE specifically chosen for USB interface designs?
USB 2.0 full-speed and high-speed standards require a 48 MHz clock reference for the internal USB PHY or PLL to generate the correct 12 Mbps or 480 Mbps bit rates. The JA-48.000-8-EHE provides a precise 48 MHz signal with ±10 ppm tolerance, which is tight enough to meet USB clock accuracy requirements while the compact 3.2 x 2.5 mm SMT package minimizes PCB area near the USB interface circuitry.
What does the ±10 ppm frequency tolerance of JA-48.000-8-EHE mean for timing-sensitive embedded designs?
A ±10 ppm tolerance on the JA-48.000-8-EHE 48 MHz crystal means the actual output frequency will deviate no more than ±480 Hz from the nominal 48 MHz across the rated operating conditions. This level of accuracy is sufficient for most USB, Ethernet, and UART baud rate generation applications in embedded microcontroller systems and ensures compliant operation within standard communication protocol timing budgets.
How does the 3.2 x 2.5 x 0.7 mm package size of JA-48.000-8-EHE compare to larger SMT crystal packages, and where does this matter?
The JA-48.000-8-EHE occupies a 3.2 x 2.5 mm PCB footprint in a low-profile 0.7 mm height package, which is the industry-standard small SMT crystal size. Compared to larger 5 x 3.2 mm crystals, this package saves approximately 50% of PCB area, making it the preferred choice for compact IoT modules, wearable electronics, and single-board computers where minimizing crystal footprint is necessary to fit the overall board size constraints.
