Con respecto a las conexiones, parece que todos los ALi usan la misma y es la que estamos usando...

DVB-S in the field, the company's products from M3326, M3327, M3328. M3329 to the M3330, to manufacture Roadmap has formed a complete series. Back in early 2004. Ali companies on the successful development of MPEG decoder and integrated QPSK demodulator being made in recent decades a functional system solution for DVB-S , and introduced M3328 integration chips, the design of the most concise and only covered RF. SDRAM and Flash, and has nine browse pictures, animation design, the shortest blind So, even in the industry at that time was known as DVB-S "version of the end", it shows you the high regard. The high degree of integration of the M3328 chip represents the domestic market of high-end products, in its publication. Pearl River Delta and Fujian provinces took the lead in the manufacturers using their products, But since the early Bug (if not tantamount to keeping programs), resulting in the bulk of the products were returned. greater initial losses, the industry has become a hot topic at the time. Through two weeks after the tackle difficult technical problem has been satisfactorily resolved.

M3328 chip encryption devices, including CA, CI and the IDE interface, and changed PVR interface; Built QPSK demodulator, Progressive scanning (P-Scan) processors, embedded video encoder function; with MP3, MPEG-2 decoding multi-sound effect. Dolby ProLogic ll, Dolby Digital and DTS decoders, HDCD decoding capability and conjecture.

Memory use was 8Mbit (1M x 8bit) FLASH. S29AL004D7 OTA102 models (U6). Data Memory is a common Etron Technology (Estron) 16Mbit (1M x 1 250Ms/s, 6-bit) EM636165TS-7 (U4) SDRAM.

In the vicinity of the interface is somewhat similar to the Main Board JPS1 patch transistor packaging methods CX1117-1.8 (U1 4). It is LDO LDO (Low Dropout Regulator) linear power supply chips, Many chip LDO production companies, such as Alpha, LT (Linear Technology) NI (Nationgal semicond uctor) and other foreign companies, domestic and Wuxi This chip is used in the production of microelectronic chips innovation. output voltage of 1.8V, providing work for the CPU power, in our common DVD decoder board computer and the chip on the main board, we can see that this kind of device.

Since the M3328 chip yet to audio converter. So adding the Main Board ET8211 few analog converter chip (U12). ET8211 through conversion from the left and right channel of the two channel audio signals RC4558 by dual operational amplifier (U11) constitute the audio amplifier were enlarged. PT8211,82V731 ET8211 and common functions, widely used in low-end products. can be reversed, and the features of the structure is very simple. 8DIP adopt a package approach.

GL506x series digital satellite receiver position the rural market, the external output interface is very simple. JACK only one audio-video output (L/R/V) and an RF modulator (RF) output of Socket. RF modulator circuit was done directly in the main board, and the week in which the inductance coil thermal Sol cementing, prevent vibration frequency drift.

It can carry out software upgrades, but not outside the RS232 serial port, but there legs bisecting Main Board (J6). both sides of the politics of the corresponding function : +5 V, TXD, RXD, GND. [B][COLOR="Red"]JTAG needle on the Main Board has reserved six, corresponding to both sides of the politics : GND, TCK, TMS, TDO, TDI, TRSTJ for executing the FLASK-line programming (ISP)[/COLOR][/B].
