CFPS-59 SMD CLOCK OSCILLATORS
ISSUE 4; 24 jULy 2009 - RoHS 2002/95/EC
Description
2.5V surface mount oscillator in a ceramic package, with a
hermetically sealed metal lid and LVPECL outputs
Package Outline
7 x 5mm
Frequency Range
40 to 270MHz
Output Compatibility & Load
LVPECL
Output Load 50 terminated to Vs-2.0V
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-59)
–40 to 85°C (CFPS-59I)
Storage Temperature Range
–55 to 125°C
Tri-state Operation
Logic ‘1’ (>70% Vs) to pad 1 enables oscillator output
Logic ‘0’ (<30% Vs) to pad 1 disables oscillator output;
the oscillator output goes to the high impedance state
No connection to pad 1 enables oscillator output
