Product Parameters Input Voltage (Core VDD): 2.25V–3.6V DC Output Voltage (VDDO): 1.8V–3.3V DC Output Frequency Range: 2.5 kHz–200 MHz Output Channels: 3 (CLK0/1/2, LVCMOS, 50Ω Impedance) Frequency Accuracy: ±0 ppm Jitter: Reference Clock: Built-In Crystal Driver (25/27 MHz External Crystal) Operating Current: ≤22 mA (VDD = 3.3V) Standby Current: ≤1 μA (Deep Sleep Mode) Temperature Range: -40°C to +85°C Communication Interface: I²C (Address 0x60, 100–400 kbps) Package: MSOP-10 🔌 Main Pin Functions VDD: Core Power (2.25V–3.6V). Decouple with 0.1 μF ceramic capacitor (≤5 mm from pin). VDDO: Output Drive Power (1.8V–3.3V). Use independent filtering (10 μF electrolytic + 0.1 μF ceramic capacitor). GND: System Ground. Requires single-point grounding (PCB copper area ≥80%). SDA/SCL: I²C Data/Clock Lines (open-drain). Use 4.7 kΩ pull-up resistors to VDD (trace length ≤10 cm, length deviation ≤2 mm). CLK0/1/2: LVCMOS Outputs. Limit load capacitance ≤10 pF ⚡ Key Features Multi-Channel Independent Synthesis: Dynamically configure 3 outputs (2.5 kHz–200 MHz) via I²C to replace crystals/VCXOs/PLLs. Glitch-Free Frequency Switching: Real-time adjustment without signal interruption (Suitable for frequency-hopping systems). Anti-Interference Design: Programmable spread spectrum modulation (SSM) suppresses EMI; separate VDD/VDDO pins enable noise isolation. Plug-and-Play: Direct square wave output compatible with FPGA, MCU, and RF digital systems.
