DVB-T receiver nrog ASI Broadcast-level professional khoom
Cov Txheej Txheem
Do you have a DVB-T receiver, how many antennas are in it, can it be ASI out?
1. Our DVB-T receiver has one-antenna, two-antenna, and four-antenna models. Some models of the DVB-T receiver have ASI output.
2. Feem ntau, ASI is input to the encoder. Do you want to output it to the decoder separately?
3. Our demodulation module, the demodulation chip above, uses a parallel interface called TSI (Nws muaj ntau cov ntaub ntawv kab dua cov ASI interface)
4. Kuj, the demodulation module does not have an MCU and cannot be provided to customers alone. It needs to be used in conjunction with our decoding board.
5. Piv txwv, Nrog peb decoding board, Peb hloov lub teeb liab ntawm lub TSI interface ntawm tus demodulation module rau hauv lub network chaw nres nkoj teeb liab (piv txwv, our one-way cofdm transparent transmission does this)
What chip did you use for your DVB-T receiver with ASI output?
DIB9090 for demodulation chip.
MSD7802 for decoding chip
Your ASI output port is SMA! There are very few 75 ohm ones.
Muaj 75 ohm ones. Qhov tseeb, the impedance of this connector has little impact on ASI. The main impact is that the cable has a greater impact.
Disagree. The impact is huge. There are also requirements for micro strips on electrical boards.
PCBA impedance is 75Ω, connector impedance is 75 txajmuag.
How can I change the frequency on your board? RS-232, or Ethernet?
Use the keyboard to change the frequency, and use the RS232 serial port to connect to the keyboard (parameter adjustment board) to adjust parameters.
Can all connectors be replaced with 75 ohm MCX?
sure, we can change the SMA connector to MCX.
Can you quote me the best price?
Do you need PCBA only or with the customized metal shell?
