/* Many Philips based tuners have a comment like this in their * datasheet: * * For channel selection involving band switching, and to ensure * smooth tuning to the desired channel without causing * unnecessary charge pump action, it is recommended to consider * the difference between wanted channel frequency and the * current channel frequency. Unnecessary charge pump action * will result in very low tuning voltage which may drive the * oscillator to extreme conditions. * |
