75Ω Driver IC for HD
Monolithic IC MM1797 Series |
|
|
[Outline]
This IC is a video driver IC that realizes the frequency characteristics necessary for analog high definition signals. It deletes S video signals (Y/C) from the video signals to be output to maintain only the composite signals (CVBS) and the component signals (PY/Pb/Pr).
This feature helps its package to be miniaturized and the mounting area to be reduced. As a video output driver, this IC is best suited to a BD/DVD player.
[Features]
1. |
Built-in LPF whose passband is 30 MHz for 1080i or 720p/XGA HD video signals. |
2. |
Rank A : Use of a new SAG correction circuit (patent pending) and reduction in the output coupling capacitance.
Rank C : Use of a positive power supply and a negative power supply to eliminate the output coupling capacitance.
Rank D/E : Use of a simple output circuit without CEand elimination of output coupling capacitance.
|
3. |
Any additional electrostatic protection circuit is not required since the video output terminal has passed the ESD aerial discharge test (conforming to IEC610000-4-2). |
