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
LVDS Signal
