Multistandard VIF-PLL with QSS-IF and

AM demodulator

Product specification

TDA9810

CHARACTERISTICS

VP = 5 V; Tamb = 25 °C; see Table 1 for input frequencies and level; input level Vi(IF)(rms) = 10 mV (sync-level for B/G,

peak white level for L); IF input from 50 Ω via broadband transformer 1 : 1; video modulation DSB; residual carrier

B/G: 10%; L = 3%; video signal in accordance with “CCIR, line 17”; measurements taken in Fig.14; unless otherwise

specified.
