The TFP410 integrates a high-speed digital interface, a T.M.D.S. encoder, and three differential
T.M.D.S. drivers. Data is driven to the TFP410 encoder across 12 or 24 data lines, along with
differential clock pair and sync signals. The flexibility of the TFP410 allows for multiple clock
and data formats that enhance system performance.

The TFP410 also has enhanced PLL noise immunity, an enhancement accomplished with on-
chip regulators and bypass capacitors.

The TFP410 is versatile and highly programmable to provide maximum flexibility for the user.
An I2C host interface is provided to allow enhanced configurations in addition to power-on
default settings programmed by pin-strapping resistors.

The TFP410 offers monitor detection through receiver detection or hot-plug detection when
I2C is enabled. The monitor detection feature allows the user enhanced flexibility when
attaching to digital displays or receivers.

M41ST85WMX6TR will pull H_RESET# low when the VCC is below Vpfd=2.6V, thus realizing the
power fail reset function and power-on reset.
