Package Outline

I

7.0 x 5.0mm SMD Ceramic Package.

Available over 0 to 70°C (CFPS-72, -73) or

–40 to 85°C (CFPS-72I, -73I)

Standard Frequency Stabilities

I

±20ppm, ±25ppm, ±50ppm, ±100ppm (inclusive of

supply voltage & output load variations over the

operating temperature range)

Operating Temperature Range

I

0 to 70°C (CFPS-72, -73)

I

–40 to 85°C (CFPS-72I, -73I)

Storage Temperature Range

Tri-state Operation

I

Logic ‘1’ to pad 1 enables oscillator output, 2.2V min

I

Logic ‘0’ to pad 1 disables oscillator output; when

disabled the oscillator output goes to the high

impedance state, 0.8V max

I

No connection to pad 1 enables oscillator output
