Philips Semiconductors
Single/multistandard VIF/SIF-PLL and
FM-PLL/AM demodulators
Product specification
TDA9817; TDA9818
CHARACTERISTICS
VP = 5 V; Tamb = 25 °C; see Table 1 for input frequencies and levels; input level Vi(VIF)(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” or “NTC-7 Composite”; measurements taken in
Fig.15; unless otherwise specified.
