9681 Implementation notes.
9685 Four AGCs are used for NTSC:
9686 (1) RF (used to attenuate the input signal in case of to much power)
9687 (2) IF (used to attenuate the input signal in case of to much power)
9688 (3) Video AGC (used to amplify the output signal in case input to low)
9689 (4) SIF AGC (used to amplify the output signal in case input to low)
9691 Video AGC is coupled to RF and IF. SIF AGC is not coupled. It is assumed
9692 that the coupling between Video AGC and the RF and IF AGCs also works in
9693 favor of the SIF AGC.
9695 Three AGCs are used for FM:
9696 (1) RF (used to attenuate the input signal in case of to much power)
9697 (2) IF (used to attenuate the input signal in case of to much power)
9698 (3) SIF AGC (used to amplify the output signal in case input to low)
9700 The SIF AGC is now coupled to the RF/IF AGCs.
9701 The SIF AGC is needed for both SIF output and the internal SIF signal to
9704 RF and IF AGCs DACs are part of AFE, Video and SIF AGC DACs are part of
9705 the ATV block. The AGC control algorithms are all implemented in
9710 (Shadow settings will not be used for now, they will be implemented
9711 later on because of the schedule)
9713 Several HW/SCU "settings" can be used for ATV. The standard selection
9714 will reset most of these settings. To avoid that the end user application
9715 has to perform these settings each time the ATV or FM standards is
9716 selected the driver will shadow these settings. This enables the end user
9717 to perform the settings only once after a drx_open(). The driver must
9718 write the shadow settings to HW/SCU in case:
9719 ( setstandard FM/ATV) ||
9720 ( settings have changed && FM/ATV standard is active)
9721 The shadow settings will be stored in the device specific data container.
9722 A set of flags will be defined to flag changes in shadow settings.
9723 A routine will be implemented to write all changed shadow settings to
9726 The "settings" will consist of: AGC settings, filter settings etc.
9728 Disadvantage of use of shadow settings:
9729 Direct changes in HW/SCU registers will not be reflected in the
9730 shadow settings and these changes will be overwritten during a next
9731 update. This can happen during evaluation. This will not be a problem
9732 for normal customer usage.
