POWER SAVING OPERATION
This PLL has a programmable power–saving scheme. The
transmit and receive counters and the reference frequency
counter can be powered down individually by setting the
TxPD enable, RxPD enable, and Ref PD enable bits of the
control register. The functions of the power down control bits
are explained in Table 2 and the programming format is in
Figure 8.
The output pins TxPS/fTx and RxPS/fRx output the status of
the internal power saving setting. If the bit TxPD enable is set
“high” (transmit counter is set to power–down mode), then the
TxPS/fTx pin will also output a “high” state. This TxPS/fTx out-
put can control an external power switch to switch off the
transmitter, as shown in Figure 17. This scheme can be
applied to the RxPS/fRx output to control the receiver power
saving operation as required.
