14 7-5 CX24118A ZIF PLL IC control Tuner control interface The CX24116 tuner control interface is compatible with CX24118A and CX24128 tuners. This interface consists of an isolated I2C-compatible serial bus and an AGC signal. Legacy tuner controls LD and FILTERV, formerly passed between the demodulator and tuner as physical signals, are accessed through tuner registers Tuner serial bus control The primary means of controlling the tuner is through the firmware, with no access from the host processor. Tuners CX24118A and CX24128 are both supported. When firmware support is not available for a tuner (tuners other than CX24118A or CX24128), tuner pass-through can be used. Figure 3 illustrates this method. Tuners CX24118A and CX24128 are both supported using this method. [Figure 3] Tuner control interface (pass-through * CX24118A is fully controlled by CX * So There is no need to set any registers of CX24118A. * For more information, Refer to the appended file. 13 / 20
