Delivery Options
■
48 hour fast make service available. Please contact our
sales office for details
Output Compatibility
■
Tri-state HCMOS/TTL (5.0V) (CFPP-12, -12I)
■
Tri-state CMOS (3.3V) (CFPP-9, -9I)
Package Outline
■
One Time Factory Programmable PLL crystal oscillator
in a SMD (surface mount device) ceramic 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-9, -12)
■
–40 to 85°C (CFPP-9I, -12I)
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 high
impedance state
■
No connection to pad 1 enables oscillator output
Marking
■
Model number (+ Operating Temperature Code; if
applicable, + Frequency Stability Code)
■
