Service Manual
The SiI9023 is a second generation panelLink Cinema receiver that is compatible with
the HDMI 1.1 (High Definition Multimedia interface)specification. The SiI9023 is capable
of receiving and outputting two channel digital audio at up to 192KHz - an excellent
solution for Digital TVs. The features of this IC are as follows.
1) Digital video interface supports video processors:
2) Analog RGB and YPbPr output: 10-bit DAC
3) Digital audio interface supports high-end audio systems:
This is a video processor IC.
This IC has the following six major functions.
1) Video Processing
2) CPU
3) Scaling, Display Processing
4) Video decoder and 3D Comb filter
5) OSD and Text
6) PC Connectivity
This is a 256Mb DDR SDRAM IC. This IC features a double-data rate dynamic random-
access memory containing 16M-bits columns by 16 bits.
In this model, it uses it as a memory for the micon and a frame memory for Video Pro-
cessor, etc.
This IC is a NOR-type 128Mbit Flash Memory.
The Flash Memory stores the main program hat is used for the CPU.
This is a 16bit D-type RATCH-3 state output IC.
On this model, the IC is used to transfer the main program from the flash memory to the
CPU.
This MSP (4410K) of single-chip Multistandard Sound Processors covers the sound
processing of all analog TV-Standards worldwide, as well as the NICAM digital sound
standards and FM stereo radio.
This is an IC for Frame Rate Converter.
This IC mainly processes I/P conversion: Standard 50/60 Hz interlaced to 50/60 Hz pro-
gressive.
It also has the following functions:
1 ) Image Improvement: (Chroma Transient Improvement, Luminance Transient
Improvement, Dynamic Contrast Improvement, Back Stretcher)
2) Film mode detection (2-2/3-2 pull down)
3) Film judder cancellation.
This IC is a line driver receiver in conformity with EIA/TIA-232-E(former RS-232C)stan-
dard.
By connecting a PC, the system can be controlled externally.
This IC is F.P.G.A (Field Pogramable Gate Arrays) for signal selector and synchronous
processing of each digitalized input signal.
This IC functions as extended I/O of the main microcontroller and controls timing of bus
signals among ICs, etc.
The MP1410 is a monolithic step down switch mode regurator with a built in internal
power MOSFET.
In this model, it works to 1.8V regurator.
The MP1583 is a step-down DC-DC converter of Class 3A current capacity.
In this model, it works to BU1.8V regurator.
This IC is a 2-wire (I2C bus type) serial EEPROM that is electrically programmable.
This IC serves to store the adjustment and other data in the adjustment process mode.
The data is given out by commands from the main microprocessor.
This IC is a 2-wire (I2C bus type) serial EEPROM this is electrically programmable.
The EEPROM chip stores the EDID data of HDMI input. This data is controlled through
I2C signals.
