描述
SI5351 2.5K-200MHz Signal Generator with STM32 TFT Display for RF Square Wave DIY Projects
Key specifications
Output interface: SMA jack
Output frequencies: F0 = F1 = 2.5 K to 200 MHz
PLL arrangement: F2 and F1 share a phase-locked loop; frequency division ratio is configurable
Supply voltage: +5 V
Why customers choose this product
Flexible frequency source: Provides a wide output range useful for many RF and timing needs without requiring multiple devices.
Phase-coherent outputs: Sharing a PLL between F2 and F1 preserves a stable phase relationship when both outputs are used together.
Easy integration: Standard SMA output and a +5 V supply make it compatible with common test equipment, RF cabling, and low-voltage systems.
What it does and how it solves problems
Supplies stable RF or clock outputs across a broad range (2.5 K to 200 MHz) for testing, synchronization, or signal generation.
Allows configurable frequency division ratios to match system requirements or to generate multiple related frequencies from a single PLL source.
Reduces system complexity by combining phase control and frequency division in one module, avoiding the need for extra synthesizers or external locking circuitry.
Important attributes
Function: Configurable RF/clock output module with phase-locked loop control for related outputs.
Compatibility: SMA jack for standard coaxial connections to test instruments, attenuators, filters, and antennas; +5 V supply compatible with many control and embedded systems.
Performance: Wide usable frequency range and PLL-based phase control for consistent relative phase between F1 and F2.
Mechanical/interface detail: Output presented on an SMA connector for straightforward cabling and integration.
Typical use scenarios
RF test bench: Provide a stable, configurable source for receiver/transmitter alignment, component testing, or laboratory measurements using standard SMA cabling.
Clock or LO source in prototype systems: Use the module as a compact, low-voltage local oscillator or timing reference where phase relationship between channels matters.
Frequency synthesis and calibration: Generate multiple related frequencies for system-level validation, PLL development, or calibration tasks where configurable division ratios simplify signal planning.
Integration notes
Power with a regulated +5 V supply.
Connect output(s) via standard SMA coaxial cables to downstream equipment.
Configure the frequency division ratio and use the shared PLL between F1 and F2 when a defined phase relationship is required.
