TDA8601
Notes
1.
The supply voltage rejection ratio is measured at the video outputs (pins 10 to 12) when a sine wave is applied on
the power supply pin (pin 1); where: V
DC
= 8 V; V
i
= 100 mV (p-p). This additional sine wave on the power supply pin
is guaranteed not to cause extraneous oscillations on the video control and fast blanking signals.
The 6 video inputs will contain the same signal. The source impedance is 50
.
The blanking offset is the level difference between the two channels when they are selected separately and, also, on
one video output. This value is measured on each video signal.
The delay between the SEL input and the video output together with the switching time of the video output is
illustrated in Fig.3. The amplitude of the video signal is 1.9 V (p-p) when the clamp is active and 1.0 V (p-p) when the
clamp is passive.
The delay between the SEL input and fast blanking output together with the switching time of fast blanking output is
illustrated in Fig.4.
The fast blanking delay between input and output is illustrated in Fig.5.
The video delay between input and output and delay differences are illustrated in Fig.6. Inputs 1 and 2 are either fast
blanking input plus a video signal or two video signals. The amplitude of the video signal is 0.5 V (p-p). The video
signal levels (i1, i2, o1 and o2) are 50% of the video amplitude. The fast blanking signal levels (i1 and o1) are 0.95 V
when the signal rises and 0.5 V when the signal falls.
