HD3SS460: HD3SS460 LN not use

Hello　Nir

Can I use a 100 Ω termination resistor?

Thanks

Is it possible to terminate all 8 unused LN pins together with a single resistor?

再度質問してしまい申し訳ありません。 すべてのピンをGNDに直接接続することは可能ですか? 感謝。

スペースが不足しているため、未使用のピンすべてに抵抗を取り付けるのは難しい場合があります。
その場合、1つの抵抗に複数の未使用ピンを接続してGNDに接続できますか?
その場合は、最適な抵抗値と接続できるピン数を教えてください。

ありがとうございます。

1つの終端抵抗を100Ωにすることは可能ですか?

感謝。

もう一つ質問があります。
SBU1-2、CSBU1-2も未使用です。
AMSLをM電圧に設定し、「All Low Speed SBUPorts HighZ」を選択します。
この場合、SBU1-2とCSBU1-2はオープンのままで大丈夫ですか?
SBUとCSBUのどちらかの手続きが必要ですか?
ありがとうございます。%MCEペーストビン%

Hello Toshihiko-san,

What is the signal speed in this application? Usually we recommend to tie the pins to ground in high frequency applications, since floating pins can produce additional noise. 

This FAQ has additional information.

Thanks,

I was able to understand and solve my previous question.
Thank you.

In addition, when setting AMSEL to the midpoint potential (M), is it okay to connect two 200kΩ resistors to +3.3V and GND respectively and input a divided voltage?
Do I need to use 10k resistors like in the recommended circuit in the datasheet?

Similarly, POL is also pulled up with 200kΩ, but does it need to be 10k?

Thank you.

Hello  Toshihiko-san,

What do you mean by midpoint potential? Which configuration are you referring to from table 1 (starting page 11 of the datasheet)? But, yes you can divide the voltage that way. As long the input signal doesn't exceed the device limits, there will be no issues. 

No, you don't have to use 10k in either case, 200k will work as well.

Thanks,

Nir
