Multistandard/MAC VIF-PLL with QSS-IF
and dual FM-PLL/AM demodulator
TDA9815
Notes to the characteristics
1.
Values of video and sound parameters are decreased at V
P
= 4.5 V.
2.
This parameter is not tested during production and is only given as application information for designing the
television receiver.
3.
Source impedance: 2.3 k
in parallel to 12 pF (SAW filter); f
IF
= 38.9 MHz.
