The CFPS-32IB 25.0MHZ is a 7 x 5mm 2.5V 50ppm surface-mount Crystal Clock Oscillator with ceramic hermetically sealed metal lid. The CFPS-32 series oscillator with logic-1 to pad-1 enables oscillator output, logic-0 to pad-1 disables oscillator output and the oscillator output goes to the high impedance state.
