CFPS-72, -73 SMD CLOCK OSCILLATORS
ISSUE 11; 1 NOVEMBER 2008 - RoHS 2002/95/EC
Description
Surface mount oscillators in a ceramic package with a
hermetically sealed metal lid available in two voltages
Fast Make Capability
Please see CFPP-72, 73 series Programmable Oscillators
for nearest equivalent fast make parts
Package Outline
7 x 5mm SMD ceramic package
Frequency Range
1.25 to 160MHz
Output Compatibility & Load
Tri-state HCMOS/TTL (5.0V) (CFPS-72)
Tri-state HCMOS (3.3V) (CFPS-73)
Maximum Capacitive Load
1.5MHz to 50MHz
50pF max
>50MHz to 80MHz
30pF max
>80MHz to 160MHz
15pF max
Frequency Stabilities
±20ppm, ±25ppm, ±50ppm, ±100ppm (inclusive of supply
voltage and output load variations over the operating
temperature range)
Operating Temperature Range
0 to 70°C (CFPS-72, -73)
–40 to 85°C (CFPS-72I, -73I)
Storage Temperature Range
–55 to 125°C
Tri-state Operation
Logic ‘1’ (2.2V min) to pad 1 enables oscillator output
Logic ‘0’ to pad 1 (0.8V max) disables oscillator output;
when disabled the oscillator output goes to the high
impedance state
No connection to pad 1 enables oscillator output
Marking Includes
