SKYSTAR2 2.6D kartınızı hızlandırın.(RESİMLİ)

[Romanenko]

skystar2 2.6 d kartının işlemcisini 66.66 mhz lik kristal çipi ile değiştirin kanal tarama hızları ve tunerın odaklanması cok hızlı olsun ve ısınma olmasın...

After short studying a card it is possible to notice on it standard four leg the quartz generator on 45Mhz on 3.3v, applied for clocking digital schemes. Having thought, it is possible to come to conclusion, that processing of a stream some DSP in chip B2C2 and that makes the generator and sets speed of work of this most DSP. As the donor the board from laser printers has been taken. On it there were 3 generators in the same case as well as on SS2 face values in 28, 48 Mhz

Donor.

The standard generator on 45Mhz has been replaced on 48Mhz In photo on the right the standard generator at the left – new.



By means of a soldering iron and there is some patience, the quartz generator has been replaced in SS2

The card was successfully defined BIOS and loading Windows. Signal with Express AM1 11051 H SR29650 has gone was successfully defined at a level of 55 %. Reception of transport flow processed a stream with very rare discontinuity. Of all above-stated it is possible to draw a conclusion, that DSP in SS2 does not suffice for correct maintenance SR=30000 about 10 % of productivity. Anyway, the increase in frequency at 6 % has appeared (almost) enough for support SR=29650
After replacement of the quartz generator on 53Mhz - Reception of transport flow easy enough could simultaneously all PIDs 80000 tcp threads simultaneously. The card has begun is assured to hold SR=29650 at o'clock of the maximal loading. Heating of chip FlexCopII subjectively has not changed. Though, very much it would be desirable to lead tool measurements. Having rummaged in antiquarian iron has been found old AGP videocard Intel 740

The quartz generator on 66 Mhz from videocard Intel 740 has been taken

Quartz generator installed on SS2

The card without problems was got and worked. Reception of transport flow successfully coped with on Yamal 90E on Klassica 3980 L at SR 38.000. TV channels in ProgDVB display also without problems... Also without problems the stream was accepted on Intelsat 702 at 54.8°E SatGate SR 40.692 with 60 Mhz quartz generator...

At absence of the necessary quartz generator it is possible to collect the simple scheme on the basis of the quartz resonator, as it has been done

Scheme on Cypress CY25814 chip

The device in operation

At present one of cards was started and works on frequency 80 Mhz

After there was an idea of installation of the quartz resonator of greater face value in the standard quartz generator from SS2. Here this miracle which successfully works

What to do at absence necessary quartz generator ?
Then there was an idea - AGP bus works on frequency 66 Mhz, and what if to take from clock generator of motherboard having connected SS2 to clock generator AGP bus ?

132 pin EDGE (AGP bus) connector at the computer motherboard

To us it is necessary connect to pin B7 (CLK), as it has been done.

The usual wire has been taken, one end is soldered to AGP to a videocard on 7 pin (to not open AGP slot)
