CFPT-5300 LEADED TCXO
ISSUE 5; 15 DECEmbEr 2009 - roHS 2002/95/EC
Description
▪
Ultra high stabilitie 14-pin DIL hermetically sealed TCXO with
wide operating temperature range. Manufactured for us by
Rakon, its wide frequency range and operating temperature
range, coupled with high stability and linear frequency pulling
make it the ideal reference oscilator. Its ability to function
down to supply voltage of 2.4V and low power consumption
makes it suitable for a wide range of applications.
