Scaler

IC200

Besides the ADC, LVDS, and scaling part, an MCU is embedded as well. All of

them are integrated into one chip.

SE758MRH-LF

Flash

Memory

IC201

Stores the MCU program embedded in the scaler. It is of a flash type and

rewritable.

MX25LV512

IC203

Stores the OSD and various timing values.

24C08

IC202

The memory to which DIGITAL DDC data is input

24C02

Regulator An IC that receives DC voltage inputs. It is used in circuits that stabilize the DC

voltage.

NCP117DT18T5G

APL1117-33VC

Panel

SE758MRH-LF

(Scaler)

Embeded MCU

Function: Receives analog/digital inputs and

scales to and outputs LVDS signals which

are fit to the panel resolution.

It works the same way as an old Micom

because it has an embedded MCU core.

But it uses external memory because it has no

MCU memory.

One EEPROM is embedded to store DDC data.

Crystal

24C08

(NVRAM)

Function: Stores OSD

values and timing

information

for each mode

MX25LV512

(Flash Memory)

Function: Stores the

MCU code (Hex) data.

Function Ass’y

Function: Transfers the inputs entered by the user to the Micom using

voltage difference.

24C02

(DDC - Digital)

Function: Stores the

digital EDID data

Key input

ISP

Digital Signal

SCL/SDA

Analog Signal

I2C
