Product data sheet
8.3.1 Mode selection of VIF AGC
8.3.2 External VIF AGC control
8.3.3 VIF AGC monitor
8.2 VIF demodulator
8.3 VIF AGC and tuner AGC
The switch takes into account correct signal selection for TAGC in the event of VIF and
DIF signal processing.
ATV demodulation using 6 MHz DVB window (band-pass) filter (for 6 MHz, 7 MHz or
8 MHz channel width).
IF frequencies adapted to enable the use of different filter configurations. The Nyquist
processing is integrated.
For optional use of standard Nyquist filter the integrated Nyquist processing can be
switched off.
Sideband switch supplies selection of lower or upper sideband (e.g. for L-accent).
Equalizer provides optimum pulse response at different standards [e.g. to cope with
higher demands for Liquid Crystal Display (LCD) TV].
Integrated sound traps.
Sound trap reference independent from received 2nd sound IF (reference taken from
integrated reference synthesizer).
IF level selection provides an optimum adaptation of the demodulator to high linearity or
low noise.
Separate passive video detector for monitoring the received IF level in combination with
AGC hold mode for diversity application.
Peak white AGC for positive modulation mode with adaptation for speed up and black level
AGC (using proven system from TDA9886).
For negative modulation mode equal response times for increasing or decreasing input
level (optimum for amplitude fading) or normal peak AGC or ultra fast peak AGC (for car
mobile).
AGC input for external control enabled via fast switching input (car mobile).
AGC hold mode (for diversity detection) via fast switching input (car mobile).
VIF AGC DC voltage monitor output (with expanded internal characteristic).
VIF AGC read out via I
