AD9850 DDS Signal Generator Module

High-Precision Direct Digital Synthesis (DDS): Powered by the Analog Devices AD9850 IC with an onboard 125MHz crystal oscillator, generating highly accurate and stable signal outputs up to 40MHz.

Dual Sine Wave & Dual Square Wave Outputs: Provides 2 complementary sine wave outputs (0 - 40MHz) and 2 square wave outputs (0 - 1MHz) for versatile circuit testing and prototyping.

Onboard Potentiometer for Square Wave Duty Cycle: Features a built-in precision rotary potentiometer to easily adjust the duty cycle threshold of the square wave output.

Flexible Serial & Parallel Interface Modes: Supports both 40-bit serial data loading and standard parallel data input modes for seamless microcontroller interfacing (Arduino, STM32, PIC, Raspberry Pi).

Integrated Low-Pass Filtering (70MHz LPF): Equipped with an onboard 70MHz low-pass LC filter to effectively suppress high-frequency harmonics and deliver clean spectral purity.

Compact Breakout Form Factor: Standard pitch pin headers allow direct mounting onto solderless breadboards or integration into custom testing jigs.

Board & Component Construction: Double-sided FR4 PCB with gold-plated pin headers, surface-mount AD9850 IC, 125MHz active crystal oscillator, and onboard voltage regulation.

Technical Specifications:

Core Chip: Analog Devices AD9850.

Clock Frequency: 125MHz active crystal oscillator.

Output Frequencies: Sine Wave: 0 - 40MHz, Square Wave: 0 - 1MHz.

Operating Voltage: 3.3V - 5V DC.

Dimensions: 4.5cm x 2.6cm (approximate).

Usage Advice: As signal frequency increases above 20 - 30MHz, sine wave output amplitude naturally decreases due to harmonic roll-off.

Maintenance & Handling: Handle by the PCB edges to prevent static discharge to the AD9850 IC. Store in an anti-static bag when not in use.

Essential DDS Signal Source for Microcontroller Projects: Position as a versatile, low-cost frequency generation module for electronics makers, ham radio builders, university labs, and circuit prototypers.

Highlight 40MHz High-Frequency Range & Dual Waveforms: Emphasize its dual sine/square wave capabilities and 40MHz top frequency as a significant upgrade over simple timer-based function generators.

Recommended Cross-Sell Add-ons: Pair with 1M BNC male to Dual crocodile clamp, Oscilloscope test cable, DSO138 2.4" TFT Digital Oscilloscope, P6100 DC-100MHz Passive Oscilloscope Probe, and XR2206 Signal Generator Sine/Triangle/Square.

High-Conversion Module Star: Feature prominently in your Signal/Frequency Module collection as an essential precision DDS breakout board.
