SDM-P234 (E)

This part amplifies the level of video signal for the digital conversion and converts from the analog video signal to the

digital video signal using a pixel clock.

The pixel clock for each mode is generated by the PLL.
The range of the pixel clock is from 25MHz to 165MHz.
This part consists of the Scaler, Flash-ROM IC which stores program data, Reset IC.

The Scaler gets the video signal converted analog to digital, interpolates input to 1900 x 1200 resolution signal and

outputs 8-bit R, G, B signal to transmitter.

Especially pre-amp / ADC / Video controller/ Transmitter are merged to one chip 'Gm1601' by Genesis.
This part transmit digital signal from the Scaler to the receiver of module.

This part consists of the two 3.3V and one 2.5V and one 1.8Vregulators to convert power which is provided 18V in

Power Board  V is provided for LCD Panel.

24V in Power Board V is provided for Inverter Part.
Also, 5V is converted 3.3V and 2.5V and 1.8V by regulator. Converted power is provided for IC in the main board.

This part contains of EMI components to comply with global marketing EMI standards like FCC,VCCI CISPR,
the circuit included a line-filter, across line capacitor and of course the primary protection fuse.

This part function is for transfer the input AC voltage to a DC voltage through a bridge rectifier and a bulk capacitor .

This part function is for transfer the primary energy to secondary through a power transformer.

This part function is to make a pulse width modulation control and to provide the driver signal to power switch,to

adjust the duty cycle during different AC input and output loading condition to achieve the dc output stabilized, and
also

the over power protection is also monitor by this part.

This part function is to feed back the dc output changing status through a photo transistor to primary controller to
achieve the stabilized dc output voltage.

This part function is to collect the any change from the dc output and feed back to the primary through photo

transistor

The inverter converts from DC24V to AC 700V and operate back-light lamp of module.
