40MHz 7050 TCXO 0.28ppm

Frequency: 40MHz
Work Temperature: -40~85℃
Reference Temperature Initial Accuracy: ±1ppm
Frequency Temperature Stability: ±0.28ppm

Our high-performance 40MHz Temperature Compensated Crystal Oscillator (TCXO) offers exceptional frequency stability of ±0.28 ppm across the full industrial temperature range (-40°C to +85°C). Housed in a robust 7.0mm x 5.0mm (7050) SMD package, this TCXO is engineered for mission-critical applications where precision timing is non-negotiable, such as 5G infrastructure and GNSS receivers.

Key Features:

Ultra-High Stability: ±0.28 ppm ensures reliable synchronization in fluctuating environments.
Wide Temperature Range: Operates flawlessly from -40°C to +85°C, meeting industrial and automotive standards.
Low Phase Noise: -140 dBc/Hz @ 1kHz, perfect for high-speed data transmission and low-jitter requirements.
Standard 7050 Footprint: Easy integration into existing PCB designs with a 7.0 x 5.0mm surface-mount package.
CMOS Output: 3.3V supply voltage with CMOS output for broad compatibility.
