نظرة عامة على المنتج
The TG3225CEN 39.000000MHZ-CNGNNB is a 39MHz temperature-compensated crystal oscillator (TCXO) from Seiko Epson’s TG3225CEN series. This TCXO provides ±0.5ppm frequency stability over -30°C to +85°C with a clipped sine wave output, operating from a 2.8V supply in a compact 3.2 x 2.5mm ceramic SMD package. The CNGNNB code specifies the stability grade, supply voltage, and operating temperature range. Designed for GPS/GNSS, telecommunications, and timing infrastructure requiring high frequency precision.
