Maximum Capacitive Load
1.5MHz to 50MHz
>50MHz to 80MHz
>80MHz to 160MHz
Frequency Stabilities
±20ppm, ±25ppm, ±50ppm, ±100ppm (inclusive of supply
voltage and output load variations over the operating
temperature range)
0 to 70°C (CFPS-72, -73)
–40 to 85°C (CFPS-72I, -73I)
–55 to 125°C
Logic ‘1’ (2.2V min) to pad 1 enables oscillator output
Logic ‘0’ to pad 1 (0.8V max) disables oscillator output;
when disabled the oscillator output goes to the high
impedance state
No connection to pad 1 enables oscillator output
