Product specification
Multistandard vision and sound-IF PLL with
DVB-IF processing
TDA9819
CHARACTERISTICS
VP = 5 V; Tamb = 25 °C; see Table 1 for input frequencies and level; input level Vi IF1-2, 4-5 = 10 mV RMS value
(sync-level for M and B/G, peak white level for L); video modulation DSB; residual carrier M and B/G: 10%; L = 3%;
video signal in accordance with “CCIR, line 17”; measurements taken in Fig.12; unless otherwise specified.
