13.5.TEA6415C
13.5.1.General Description
The main function of the IC is to switch 8 video input sources on 6 outputs. Each output can be
switched on only one of each input. On each input an alignment of the lowest level of the signal is made
(bottom of synch. top for CVBS or black level for RGB signals). Each nominal gain between any input
and output is 6.5dB. For D2MAC or Chroma signal the alignment is switched off by forcing, with an
external resistor bridge, 5 V

(bottom of synch. top for CVBS or black level for RGB signals). Each nominal gain between any input
and output is 6.5dB. For D2MAC or Chroma signal the alignment is switched off by forcing, with an
external resistor bridge, 5 V
DC
on the input. Each input can be used as a normal input or as a MAC or
Chroma input (with external resistor bridge). All the switching possibilities are changed through the
BUS. Driving 75
BUS. Driving 75
load needs an external transistor. It is possible to have the same input connected to
several outputs. The starting configuration upon power on (power supply: 0 to 10V) is undetermined. In
this case, 6 words of 16 bits are necessary to determine one configuration. In other case, 1 word of 16
bits is necessary to determine one configuration.

13.6.STV9379FA
13.6.1.Description
Designed for monitors and high performance TVs, the STV9379FA vertical deflection booster can
handle flyback voltage up to 90V. Further to this, it is possible to have a flyback voltage, which is more
than the double of the supply (Pin 2). This allows to decrease the power consumption, or to decrease
the flyback time for a given supply voltage. The STV9379FA operates with supplies up to 42V and
provides up to 2.6APP output current to drive the yoke. The STV9379FA is offered in HEPTAWATT
package.
