Multistandard VIF-PLL with QSS-IF
and dual FM-PLL/AM demodulator
Product specification
TDA9814T
CHARACTERISTICS
VP = 5 V; Tamb = 25 °C; see Table 1 for input frequencies and carrier ratios; input level Vi IF 1-2 = 10 mV RMS value
(sync-level for B/G, peak white level for L); video modulation DSB; residual carrier B/G: 10%; L = 3%; video signal in
accordance with “CCIR, line 17”; measurements taken in Fig.13; unless otherwise specified.
