Logic ‘1’ to pad 1 enables oscillator output
Logic ‘0’ to pad 1 disables oscillator output; when disabled
the oscillator output goes to the high impedance state
No connection to pad 1 enables oscillator output

Operating Temperature Code: I = –40 to 85°C, S = –20 to 70°C, Not applicable for –10 to 60°C
Frequency Stability: G = ±20ppm, A = ±25ppm, B = ±50ppm, C = ±100ppm
*Note: ±20ppm & ±25ppm over -40+85°C (codes IG & IA ) & ±20ppm over –20+70°C (code SG) are not available
Please note that the rise and fall times listed are the maximum values we specify to cover various frequency breaks. In practice the actual values are generally
lower depending upon the spot frequency chosen. For typical values please contact our sales office.
