Abracon O-CS8 Series OCXO Oscillators

Abracon O-CS8 Series Oven Controlled Crystal Oscillator (OCXO) Oscillators feature ultra-low phase noise performance, small size, and precision SC-cut crystal. These oscillators offer -10dBc/Hz improvement of close-in phase noise (-105dBc/Hz @10Hz) and an outstanding -15dBc/Hz improvement (-180dBc/Hz @100kHz). The OCXO  oscillators operate at 3.3V or 5V voltage, -20°C to 70°C temperature range and 100MHz frequency. These OCXO oscillators deliver 15dBm sine wave output and up to ±100ppb frequency stability. The O-CS8 oscillators are available in 14mm x 21.08mm x 7.5mm SMD package dimensions. These oscillators are part lead-free and RoHS compliant. Typical applications include instrumentation, radars, high-end synthesizers, test and measurement, telecommunication systems, and data communication.
