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. Generally, 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 (it has many more data lines than the ASI interface) 4. Also, 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. For example, with our decoding board, we convert the signal from the TSI interface of the demodulation module into a network port signal (for example, 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.

There are 75 ohm ones. In fact, 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 ohms.

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?

帶有 asi 的 DVB-T 接收器 2024

你有DVB-T接收器嗎, 其中有幾個天線, 可以是ASI?

1. 我們的DVB-T接收器有一個Antenna, 兩 - 安特納, 和四個安德滕納模型. DVB-T接收器的一些模型具有ASI輸出.

2. 通常, ASI輸入了編碼器. 您想分別輸出到解碼器嗎?

3. 我們的解調模塊, 上面的解調芯片, 使用稱為TSI的並行接口 (它比 ASI 介面有更多的數據線)

4. 也, 解調模塊沒有MCU，不能單獨提供給客戶. 它需要與我們的解碼板一起使用.

5. 例如, 與我們的解碼板, 我們將解調模組TSI介面的訊號轉換為網口訊號 (例如, 我們的單向COFDM透明傳輸可以做到這一點)

您使用ASI輸出的DVB-T接收器使用了什麼芯片?

DIB9090用於解調芯片.
MSD7802用於解碼芯片

您的ASI輸出端口是SMA! 很少 75 歐姆.

有 75 歐姆. 事實上, 該連接器的阻抗對ASI的影響很小. 主要影響是電纜具有更大的影響.

不同意. 影響很大. 還需要在電板上微型帶.

PCBA阻抗為75Ω, 連接器阻抗是 75 歐姆.

我該如何更改板上的頻率? RS-232, 或以太網?

使用鍵盤更改頻率, 並使用RS232串行端口連接到鍵盤 (參數調整板) 調整參數.

所有連接器都可以替換 75 歐姆MCX?

當然, 我們可以將SMA連接器更改為MCX.

你能引用我最優惠的價格嗎?

您僅需要PCBA還是使用定制的金屬外殼?
