| 690 | * Philips FI1216MK2 remark from specification : |
||
| 691 | * for channel selection involving band switching, and to ensure |
||
| 692 | * smooth tuning to the desired channel without causing |
||
| 693 | * unnecessary charge pump action, it is recommended to consider |
||
| 694 | * the difference between wanted channel frequency and the |
||
| 695 | * current channel frequency. Unnecessary charge pump action |
||
| 696 | * will result in very low tuning voltage which may drive the |
||
| 697 | * oscillator to extreme conditions. |
||
| 698 | * |
||
| 699 | * Progfou: specification says to send config data before |
||
| 700 | * frequency in case (wanted frequency < current frequency). |
