... The TDA18218HN integrates the overall tuning function, including selectivity and provides a low-IF output signal. The TDA18218HN uses integrated IF filters to support 6 MHz, 7 MHz or 8 MHz channel bandwidths. The TDA18218HN requires only one single 16 MHz crystal for clock generation. A clock signal is available on crystal oscillator output pins (XTO_P / XTO_N) to synchronize the channel decoder ...

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 ...

... 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. The following blocks are turned off when programming a power-down: • AGC2 and its level detector • ...
