TDA9897; TDA9898
Multistandard hybrid IF processing
8.3.3 Tuner AGC
Independent integral tuner gain control loop (not nested with VIF AGC). Integral
characteristic provides high control accuracy.
Accurate setting of tuner control onset (TOP) for integral tuner gain control loop via
I2C-bus.
For L standard, TAGC remains VIF AGC nested, as from eld experience in the past this
narrowband TAGC gives best performance.
Thus two switchable TAGC systems for negative/DIF and positive modulation
implemented.
L standard tuner time constant switching integrated (= speed up function in the event of
step into high input levels), to speed up settling time.
For TOP setting at L standard, additional adjustment via optional potentiometer or I2C-bus
is provided.
Tuner AGC status bit provided.
8.4 DIF/SIF FM and AM sound AGC
External AGC control input for DIF. DIF includes direct IF and low IF.
Integrated gain control loop for SIF.
AGC control for FM SIF related to used SAW bandwidth.
Peak AGC control in the event of FM SIF.
Ultra fast SIF AGC time constant when VIF AGC set to ultra fast mode.
Slow average AGC control in the event of AM sound.
AM sound AGC related to AM sound carrier level.
Fast AM sound AGC in the event of fast VIF AGC (speed up).
SIF/FM AGC DC voltage monitor output with expanded internal characteristic.
8.5 Frequency phase-locked loop for VIF
Basic function as previous TDA9887 design.
PLL gating mode for positive and negative modulation, optional.
PLL optimized for either overmodulation or strong multipath.
