CFPS-53, -54, -55, -56 SMD CLOCK OSCILLATORS
ISSUE 4; 6 jANUARY 2009 - RoHS 2002/95/EC
Description
Surface mount oscillators in a ceramic package with a
hermetically sealed metal lid available in a range of voltages
Fast Make Capability
Please see CFPP-54, -56, -58 series Programmable
Oscillators for nearest equivalent fast make parts
Package Outline
2.5 x 2mm
Frequency Range
0.75 to 50MHz
Output Compatibility & Load
Tri-state CMOS
Drive Capability 15pF max
Frequency Stabilities
±30ppm, ±50ppm, ±100ppm (inclusive of supply voltage
output load variations over the operating temperature range)
Operating Temperature Ranges
–20 to 70°C (CFPS-53, -54, -55, -56)
–40 to 85°C (CFPS-53I, -54I, -55I, 56I)
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-53
2.5V CFPS-54
3.0V CFPS-55
3.3V CFPS-56
Phase jitter - examples:
12.0MHz
