Power Supply Voltage
This circuit is used in a cordless telephone handset and
base unit. The handset is battery powered and can operate
on two ro three NiCad cells or on 5.0 V power.
PLL Frequency Synthesizer General Description
Figure 8 shows a simplified block diagram of the
programmable universal dual phase locked loop (PLL). This
dual PLL is fully programmable thorugh the MCU serial
interface and supports most country channel frequencies
including USA (25 ch), France, Spain, Australia, Korea, New
Zealand, U.K., Netherlands and China (see channel
frequency tables in Appendix A).
The 2nd local oscillator and reference divider provide the
reference frequency for the Rx and Tx PLL loops. The
programmed divider value for the reference divider is
selected based on the crystal frequency and the desired Rx
and Tx reference frequency values. Additional divide by 25
and divide by 4 blocks are provided to allow for generation of
the 1.0 kHz and 6.25 kHz reference frequencies required for
the U.K. The 14–bit Tx counter is programmed for the desired
transmit channel frequency. The 14–bit Rx counter is
programmed for the desired first local oscillator frequency. All
counters power up in the proper default state for USA
channel #6 and for a 10.24 MHz reference frequency crystal.
Internal fixed capacitors can be connected to the tank circuit
of the 1st LO through microprocessor control to extend the
sensitivity of the 1st LO for U.S. 25 channel operation.
