MC44BS374T1 High Frequency Characteristics
Sound subcarrier harmonics
(Fp n Fs)
Second harmonic of chroma
subcarrier
Chroma / Sound intermodulation:
Fp ( Fsnd - Fchr )
Fo (picture carrier) harmonics
Out band (picture carrier)
spurious
In band spurious (Fo @ 5 MHz)
Note: 1: Picture carrier harmonics are highly dependant on PCB layout and decoupling capacitors.
Note: 2: See “Characterization Measurement Conditions” on page 15.
