CFPS-112, -113, -114, -115 SMD CLOCK OSCILLATORS
ISSUE 3; 20 jAnUARy 2009 - RoHS 2002/95/EC
Description
Low phase noise surface mount oscillators in a ceramic
package with a hermetically sealed metal lid, available in a
range of voltages
Package Outline
2.5 x 2mm
Frequency Range
26 to 44MHz
Output Compatibility & Load
Tri-state CMOS
Drive Capability 15pF max
Frequency Stabilities
±30ppm, ±50ppm, ±100ppm (inclusive of supply voltage and
output load variations over the operating temperature range)
Operating Temperature Ranges
–20 to 70°C ( CFPS-112, -113, -114, -115 )
–40 to 85°C ( CFPS-112I, -113I, -114I, 115I )
Storage Temperature Range
–55 to 100°C
Tri-state Operation
Logic ‘1’ (>80%Vs) to pad 1 enables oscillator output
Logic ‘0’ (<20% Vs) 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
Supply Voltage
1.8V CFPS-112
2.5V CFPS-113
3.0V CFPS-114
3.3V CFPS-115
