.. CRYSTAL CLOCK OSCILLATORS Frequency Selectable Differential Sine Wave Data Sheet 0549B Rev. B SY-A6A70 Series Description The SY-A6A70 Series of quartz crystal oscillators provides a Frequency Selectable Differential Sine Wave signal. The oscillator frequency is set by the voltage applied to the frequency select pin. The two selectable frequencies can be any discrete frequency selected within the range listed below. This device is to operate using positive voltage and uses multiple ground pins for improved signal integrity. Features - Wide frequency range - 250MHz to 1.7GHz - User specified tolerance from ±20ppm - Will withstand SMD reflow temperatures of 183°C for 4 minutes maximum - High shock resistance, to 1000g - Low Jitter Wavecrest jitter characterization available - Low Phase Noise of -135d B Phase Noise characterization available Electrical Connection Pin Connection - High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions - Overtone technology - High Q Crystal actively tuned oscillator circuit - Power supply decoupling internal - Cover connected to ground - No internal PLL avoids cascading PLL problems - High frequencies due to proprietary design 1 2 3 4 5 6 7 8 VCC Ground NC or Ground Q Output /Q Output Ground Frequency Select Enable 357 Beloit Street, P.O.
