7. VREF pin (Pin 14)
Do not connect this pin to an external load that might cause AC signals to flow, which will cause IC
malfunctions. When connecting a DC load, make sure that the current flowing from this pin is kept below
2mA.
8. YTRAP pin (Pin 17)
There are the following two means of reducing cross color generated by subcarrier frequency components
contained in the Y signal.
(1)
Install a capacitor of 30 to 68pF between YTRAP and GND. Decide the capacitance by conducting image
evaluation, etc., giving consideration to both cross color and resolution.
Relations between capacitance and image quality are as follows:
(2)
Connect a capacitor C and an inductor L in series between YTRAP and GND. When the subcarrier
frequency is fo, the values C and L are determined by the equation fo =
. Decide the values in
image evaluation, etc., giving consideration to both cross color and resolution.
Relations between inductor values and image quality are as follows:
For instance, L = 68µH and C = 28pF are recommended for NTSC. It is necessary to select an inductor L
with a sufficiently small DC resistance. Method (2) is more useful for achieving a higher resoluation than
method (1). When an even higher resolution is necessary, use of the S terminal (YOUT and COUT) is
recommended.
9. Driving COUT (Pin 15), YOUT (Pin 16), CVOUT (Pin 20), and B.G.R OUT (Pins 21, 22 and 23) outputs
In Pin Description, "Capable of driving a 75
Ω load" means that the pin can drive a capacitor +75Ω +75Ω
load shown in the figure below. In other words, the pin is capable of driving a 150
Ω load in AC.
Keep in mind that the pin is incapable of driving a 150
Ω load in DC load in DC direct coupling.
10. This IC employs a number of 75
Ω driver pins, so oscillation is likely to occur when measures described in
Nos. 4 and 6 are not taken thoroughly. Be very careful of oscillation in printed circuit board design and
carry out thorough investigations in the actual driving condition.
