Advanced Frequency Control: The SI5351A module provides precise clock signal generation, adjustable from 2.5 kHz to 200 MHz, suitable for applications requiring accurate timing. Versatile Use: Ideal for amateur radio, telecommunications, and electronic experiments. Supply Voltage: +5 V Output Frequency: F0 = F1 = 2.5 kHz to 200 MHz; F2 and F1 share a phase-locked loop with configurable frequency division ratio. Output Interface: SMA female Configurable Minimum Step: 1 Hz (with STM32 microcontroller and 1.3-inch TFT display) Product appearance and printed markings may vary by batch, but functionality is unaffected. Color: Random (no color selection available) Material: PCB Package Contents: 1 x SI5351 Module Note: Lighting conditions and display settings may cause slight color variation between the image and the actual product. Measurement tolerance: ±1–3 cm.
