Service Manual
The SiI9025 is a second generation panel Link Cinema receiver that is compatible with
the HDMI 1.2 (High Definition Multimedia interface) specification. The SiI9025 is capa-
ble 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 IC is a power supply for the switching regulator on the primary side,
Overvoltage/overcurrant protection circuit, other protection circuits and control circuits
are built in this IC.
This IC is a high performance CMOS super technology 16Mbit Flash Memory.
Start software (loader) for the CPU with a built-in digital processor and application soft-
ware have been written on this Flash Memory.
The digital processor reads these softwares on start-up and implements them.
This IC is an alignment-free multistandard (PAL, SECAM and NTSC) vision and sound
IF signal PLL demodulator for positive and negative modulation, including sound AM
and FM processing.
This IC is an OFDM demodulation single chip which converts the IF input signal of
OFDM into the MPEG2 signal and outputs it, and is a demodulation IC for terrestrial
broadcasting including compressed video, audio, and data service.
This IC complies with DVB-T(ETS 300 744).
