Abstract
A dual time/frequency generation apparatus having a first and a second time/frequency generator for generating time/frequency signals in a code division multiple access CDMA system, including: a first time/frequency dualizing unit for mutually synchronizing a first and a second time clock, 10 MHz frequencies, and time data TOD signals respectively received from the first and second time/frequency generators in accordance with the delay value information and monitoring the operation of a second time/frequency dualizing unit; a second time/frequency dualizing unit for synchronizing the first and second time clocks, 10 MHz frequencies, and time data TOD signals respectively received from the first and second time/frequency generators according to delay value information and monitoring the operation of the first time/frequency dualizing unit to control its output; and a time/frequency out put unit for selecting and outputting one of the other output signs from the first and second time/frequency dualizing units.
