How can I program the CY27410FLTXI with I2C? In the jic file created by Clock Wizard 2.2, it is unclear what value should be written to which address. Clock Wizard 2.2 cannot be used because the program is not a Windows environment. Please give me some advice.

This is the project that was sent to me in the previous question. https://community.infineon.com/t5/Clocks/CY27410FLTXI/m-p/331395#M609

我們使用了 CY51x7 IC，我們嘗試將低頻晶振設置為 LFF 模式。

我們要使用 50MHz 的晶振，我們按照 LFF 晶振的振盪器相關參數設置。

我們設置振盪器相關參數和 XT-Pattern。但

我們發現如果我們使用 XO_DOUBLER_ENB =1（禁用），我們可以獲得 50MHz 輸出，但如果我們使用 XO_DOUBLER_ENB=0（啟用），我們無法獲得 100MHz 頻率輸出。x

我們如何獲得正確的參數？我們在編程規範中找不到更詳細的寄存器信息，如 XO_CAP 和 XO_AMPLICE。如何獲得更詳細的信息？

How should I calculate the power consumption? Is there a spreadsheet that can be calculated?

The data sheet have IDDs. However, the number of descriptions is small and the conditions are quite limited.

Thanks,

What is the output impedance of CY27410?

In the "Test and Measurement Circuits" of the data sheet, the test environment is described as 50 ohms for single end and 100 Ω for differential. Is it this value?

Thanks,

We used the CY2071AF as the PLL in our project, as the datasheet mentioned it should be programmable(EPROM) in the field, but we keep failing in the over-write the code into the chip which may be had the code inside.
1. May you please kindly help us to provide some suggestion how to overcome this issue?

2. Or the CY2071 series are the "one time use" EPROM? Once the programmed, then can't erase anymore?

3. If it the multi-times EPROM, how can we use the way to erase the content? 

We using the Cypress FTG programmer CY3670.

Appreciate for your kindly help!

Best regards,
