Output Compatibility
■
Tri-state HCMOS/TTL (5.0V) (CFPP-57, -57I)
■
Tri-state HCMOS (3.3V) (CFPP-131, -131I)
Package Outline
■
One Time Factory Programmable PLL crystal oscillator
in a SMD (surface mount device) plastic encapsulated
package
Standard Frequency Stabilities
■
±25ppm, ±50ppm, ±100ppm (inclusive of supply voltage
& output load variations over the operating
temperature range)
Operating Temperature Range
■
0 to 70°C (CFPP-57, -131)
■
–40 to 85°C (CFPP-57I, -131I)
Storage Temperature Range
■
–55 to 125°C
Tri-state Operation
■
Logic ‘1’ to pad 1 enables oscillator output
■
Logic ‘0’ to pad 1 disables oscillator output. When
disabled the oscillator output goes to the higher
impedance state
■
No connection to pad 1 enables oscillator output
Marking
■
Model number (+ Operating Temperature Code; if
applicable, + Frequency Stability Code)
■
Frequency
Minimum Order Information Required
■
Frequency + Model Number + Operating Temperature
Code (if applicable) + Frequency Stability
