In the frequency area of 1 – 137 MHz, the SMD clock oscillators of the “LPO” series, available from the warehouse, have a standard frequency stability of ±20ppm@-40/+85°C. The standard rate of ageing is ±3ppm max. after 10 years. We recommend using the power supply voltage range of 2.25 – 3.63 VDC … read more >>
