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.
