Product details
Product Overview
The RFSOSC-SFN6D is a compact 100 MHz oven-controlled crystal oscillator (OCXO) offering ultra-low phase noise and excellent frequency stability in a small 10.2 × 10.2 × 5.6 mm 4-pin package. It provides ±0.3 ppm calibration accuracy at 25 °C, ±0.1 ppm temperature stability over a –45 to +75 °C window, and ±0.5 ppm first-year aging, ideal for space-constrained precision timing and frequency reference applications.
The oscillator outputs a sine wave at ≥5 dBm into 50 Ω, supports voltage control (0–5 V, ≥±0.7 ppm pull range), and operates from a single +5 V supply.
