Description  
I
The CFPT-5300 series of temperature compensated  
crystal oscillators (TCXOs), provide for ultra high stabilities  
down to 0ꢀ3ppm and operating temperature ranges as wide  
as -55 to 95°Cꢀ Housed in an industry standard 4 pin  
DIL 14 package, the oscillator uses C-MAC’s latest  
custom ASIC “Pluto”, a single chip oscillator and  
analogue compensation circuitꢀ Its wide frequency  
range, operating temperature range, coupled with it’s  
high stability and linear frequency pulling make it the  
ideal reference oscilatorꢀ Its ability to function down to  
supply voltage of 2ꢀ4V and low power consumption  
makes it suitable for a wide range of applications
