LMC567: Data sheet anomaly

Part Number: LMC567


Hi I have been reading the data sheet, and to me, it is written incorrectly.  Can you put me right?

 

10.2.2.1 Timing Components
As VCO frequency (FOSC) runs at twice the frequency of the input tone, the desired input detection frequency can be defined by Equation 7:

 

FINPUT  = 2 FOSC                                                                                                                    (7)

 


This (to me) is a contradiction.  Should it not be FINPUT = FOSC/2  or   2 FINPUT = FOSC?
