NOTE:
1. Product of input modulation f
at 4.43MHz p-p deviation and f
2
at 6MHz, 2MHz p-p deviation, (PAL
chroma and sound subcarriers).
2. Ratio of luminance bar amplitude (100% white), 13.5MHz p-p deviation, to output rms noise in 6MHz
bandwidth with no input modulation.
3. The above characteristics were measured in the Application circuit shown in Fig.10, with an input power of
-50dBm and(RFIN) =480MHz, unless otherwise stated.
