The Pocket Reference Oscillator (PRO Series) is the industry’s first frequency control product to integrate a complete HCMOS crystal clock oscillator in a rugged SMA housing. Connecting the PRO Series’ female SMA side to +3.3 VDC produces a clean, low-jitter signal from the male SMA side. In effect, each PRO is a fixed frequency portable crystal generator. The oscillator offers frequency stability of 䔽 ppm over 0°C to 70°C (operating temperature range rated at -40°C to 85°C; storage -45°C to 90°C).
