Video buffer
A video buffer is built into the video module to enable the
unit to drive a 75 Ω load directly. In case it is required to
use the FI1216MF MK2 as a replacement for the FI1216 in
the same videocard, it is necessary to replace the 75 Ω
series resistor in the video card by a 0 Ω series resistor. At
the same time the 22 kΩ series resistor in the tuning
supply must be removed.
I²C-bus load
The FI1216MF MK2 contains a series resistor (R = 100 Ω)
in the SCL and SDA lines. Both lines also have a
capacitive load of typical 56 pF (see Fig.3).
