Key benefits Precise, stable timing: built-in 25 MHz active crystal with 50 ppm accuracy delivers a reliable frequency reference; step accuracy 0.1 Hz enables fine frequency adjustments. Wide system compatibility: 2.3 V–5.5 V operating range supports common logic levels (including 3.3 V and 5 V systems), making integration with a broad range of controllers and modules straightforward. Rugged performance: rated for operation from -40 to +105 °C, suitable for demanding or outdoor environments. Simplified signal conditioning: integrated high-speed amplifier (300M) with additional low-pass filtering reduces external component count and eases design of clean, amplified signals. Technical highlights Frequency source: built-in 25 MHz active crystal, accuracy 50 ppm Frequency resolution: step accuracy 0.1 Hz Operating voltage: 2.3 V to 5.5 V Temperature range: -40 to +105 °C Integrated amplifier and filtering: high-speed amplifier 300M plus low-pass filtering Why this solves common problems Eliminates the need to source and tune an external frequency reference: the onboard 25 MHz crystal and fine step accuracy give stable timing without extra modules. Reduces BOM and PCB complexity: the integrated 300M amplifier plus low-pass filter handles amplification and basic noise shaping on-board, cutting or simplifying external filtering/amplification stages. Reliable across environments: the wide temperature rating ensures predictable operation in industrial, automotive-adjacent, or outdoor applications where temperature swings are expected. Practical applications Embedded systems and microcontrollers: use as a precise clock/reference input for MCUs, FPGAs, or communication peripherals requiring a stable 25 MHz source. High-speed signal front end: amplify and condition high-frequency signals before digitization or further processing, benefiting from the built-in 300M amplifier and filtering. Industrial and outdoor electronics: deploy in sensor gateways, control units, or other equipment that must operate reliably from -40 to +105 °C and across common supply voltages. Integration notes Power: design for any supply between 2.3 V and 5.5 V; this supports typical 3.3 V and 5 V systems without level-shifting for the reference source. Temperature: specified to perform across -40 to +105 °C; plan thermal layout and enclosure accordingly. Signal conditioning: the on-board 300M amplifier and low-pass filter simplify front-end design but evaluate filtering needs based on your downstream bandwidth and noise requirements.
