SMD3225 (3.2 × 2.5 mm), approximately 0.65 mm in height, with a pin-free package Common PCB pad design: The center is the crystal contact area, and grounding pads are set around it to reduce noise For reflow soldering, it is recommended to follow the JEDEC J-STD-020 chip placement process for a 260°C three-reflow procedure
Typical application scenarios
✅ system clock output of MCU/DSP/FPGA
✅ USB controller and PHY clock source
✅ frequency reference in timers, RTCS and communication devices
✅ sampling clock of ADC/DAC module
✅ frequency control of high-frequency communication protocols (such as Ethernet PHY, CAN, SPI)
Application circuit suggestions
On the system board, FL2500350 is usually configured with a matching capacitor between the crystal input pins of the MCU. The classic connection is as follows: MCU XTAL_IN -----┬---- FL2500350 ----┬----- MCU XTAL_OUT | | +---- C1 12pF ------+ +---- C2 12pF ------+ | | GND GND The capacitance value is recommended to be consistent with the crystal load capacitance (12 pF). It is recommended to lay copper beneath the ground level to enhance frequency stability and reduce EMI influence
