... NXP Semiconductors and 8 MHz channel bandwidths). The TDA18218HN requires a single 16 MHz crystal for clock generation MHz differential sine wave clock reference is available to drive a channel decoder. 8.1 AGC1 stage The TDA18218HN embeds 2 different RF amplifiers with internal gain control. The first stage, AGC1, behaves like a LNA (Low noise amplifier); its gain can take 4 different values (15 dB and 6 dB). Purpose of this amplifi ...

... NXP Semiconductors It should be noted that the level control is always operating. The strategy of the level detection has to be adapted for each type of channel decoder. It must be defined to satisfy ADC sampling (minimum level, ADC headroom). All AGC amplifiers are controlled independently. 8.4 Power-down mode The TDA18218HN can be programmed in Standby mode ...
