OPERATING PRINCIPLES OF THE CIRCUIT COMPONENTS

IC706 Analog-digital tuner inte-

gration

(IC-SMD Si2151-A10-GMR)

IC706 Analog-digital tuner IC has two differ-

ent blocks. It communicates with Main IC using

I2C protocol. Thus, it locks into two set chan-

nels. Tuner 1 block in IC is used for analog

broadcast and CVBS mark is sent to Main IC by

demodulation. Both tuner blocks can be used for

digital broadcasts. IF signal of desired channel

is sent to demodulator IC. IC700 is supplied by

3.3V_FET.

IC702 Satellite Tuner

(IC-SMD

RDA16110SW QFN40 T&R)

IC702 satellite tuner IC obtains inter frequency

signal of digital broadcast, similar to the tuner

in our chassis; filters this carrier frequency from

other frequencies and sends video and audio

data on it to the demodulator after loading IF

on inter-frequency. DVB-S2 compatible tuner

also enables viewing HD broadcast from the

satellite. It operates with 3.3V supply. And its

outputs are directly sent to the demodulator.

IC705 LNB regulator

(IC-SMD LNB-

H26LSPQR QFN T&R)

This integrated circuit adjusts LNB voltage ac-

cording to the data received from IC through

I2C line. High band-low band, vertical-horizon-

tal selection, DiSEqC selection are all done ac-

cording to the data this integrated circuit sends

to LNB. It is supplied 12 V power.

IC700,701 Demodulator IC

(, IC-

SMD SI21692-C55-GMR QFN T&R)
IC700,7 01 DVB-T,T2,C,S,S2 is dual demodula-

tor (decoder) IC. Digital broadcasts selected

from digital tuner (Terrestrial and Cable) and

satellite tuner CIs provide input for demodu-

lator CI. There are two different demodulator

block in CI. Demodulator integrated circuit

receives video and audio data loaded on the

carrier frequency and this data is separated

from the carrier frequency and converted

to the form required for transmission to the

main IC. For the efficient transmission of the

signal, digital image is sent to the main inte-

grated circuit as transport stream.
