74.25MHz LVDS Differential Crystal Oscillator, 2520 SMD 1.8V, 0.5ps Low Jitter, -40~+85℃ Industrial Grade

Frequency: 74.25MHz
Supply Voltage: 1.8V
Frequency Stability: ±30ppm
Output Type: LVDS
Operating Temperature Range: -40~85℃

The 74.25MHz LVDS Differential Crystal Oscillator is a high-performance clock source designed for demanding high-speed data applications. Featuring a compact 2520 SMD package (2.5x2.0mm) and operating at a low voltage of 1.8V, this oscillator delivers exceptional frequency stability (±30ppm) and ultra-low phase jitter of only 0.5ps rms.

The LVDS (Low Voltage Differential Signaling) output ensures high noise immunity and low electromagnetic interference (EMI), making it perfect for high-definition video processing and optical communication modules. Engineered for reliability, it operates across an industrial temperature range from -40°C to +85°C.

Key Features

Target Frequency: 74.250000 MHz (Optimized for HD Video/HDMI).

Output Type: LVDS Differential output for high-speed integrity.

Ultra-Low Jitter: 0.5ps rms (12kHz to 20MHz) for clean signal transmission.

Miniature Footprint: 2.5 x 2.0 x 1.1 mm (max) SMD package.

Industrial Grade: Reliable operation from -40°C to +85°C.

Power Efficiency: 1.8V supply voltage with Standby function (OE).

Typical Applications

Video Systems: HDTV, Camera, HDMI/DisplayPort interfaces.

Networking: Gigabit Ethernet, Fiber Channel, SONET/SDH.

Computing: High-speed FPGA and SoC clocking, PCIe storage.
