Preliminary
PLL
The figure below shows a simplified block dia-
gram of the programmable universal dual
phase-locked loop (PLL). It provides accurate
channel frequencies for cordless phone.
The PLL contains one 14-bit programmable
counter, one phase detector, charge pump, un-
lock detector and the 2nd local oscillator. The
12-bit programmable counter provides the ref-
erence frequency for the receiver (RX) and
transmitter (TX) loops.
This dual PLL is fully programmable through
the C serial interface and supports most coun-
try channel frequencies including USA, Spain,
Australia, Korea, New Zealand, U.K., Nether-
lands, France, Taiwan, and China.
