Inventor: OZAKA MASAHIKO
IPC: H03L7/183
Filed: 2001-10-19
Abstract: PROBLEM TO BE SOLVED: To provide a PLL circuit suitable for cellular phones. SOLUTION: A CPU 6 sends a DATA signal and a CLK signal to a PLLIC 1 to set desired frequencies for a programmable RF counter 2 or a programmable reference counter 9.
