CFPS-12 SMD CLOCK OSCILLATORS
ISSUE 3; 1 NOvEMbER 2008 - RoHS 2002/95/EC
Description
5.0V surface mount oscillator in a ceramic package, with a
hermetically sealed metal lid
Fast Make Capability
Please see CFPP-12 series Programmable Oscillators for
nearest equivalent fast make parts
Package Outline
5 x 3.2mm
Frequency Range
1.8 to 50MHz
Output Compatibility & Load
Tri-state HCMOS (5.0V)
Drive Capability 50pF / 10TTL max
Frequency Stabilities
±25ppm, ±50ppm, ±100ppm (inclusive of supply voltage and
output load variations over the operating temperature range)
Operating Temperature Ranges
–
10 to 70°C (CFPS-12)
–
40 to 85°C (CFPS-12I)
Storage Temperature Range
–55 to 125°C
Tri-state Operation
Logic ‘1’ (>2.2V) to pad 1 enables oscillator output
Logic ‘0’ (<0.8V) 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
Output voltage Levels/Output Current
Logic ‘1’ = 4.5V min, IOH –16mA max
Logic ‘0’ = 0.5V max, IOL 16mA max
Standby Current
10A max
Start Up Time
10ms max
Environmental
Shock: MIL-STD-202F, Method 213B (1000G, 0.5ms, 1/2
sine)
Vibration: MIL-STD-202F, Method 204D, Test condition D
