Hello, I was wondering what is needed to reprogram the CY22393. It came programmed with the default serial address of 69H, but I need to change the address to something different for project use. I also have questions on the set up, reading back, it looks like I2C programming can only be used for volatile memory. Will i need to pick up a programmer to reprogram the serial address? Also, any tips and tricks to help me get started with reprogramming the CY22393 device would be greatly appreciated. i couldn't only find posts about this product and my specific issue unless they were from 2008-2009. so i wasnt sure how valid those post still were.
Thanks for the help.
Hello,
in our design we are using the obsolete CY7B992-7JI. Is a replacement available?
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,

Hello ,
Please provide the Reliability (JEDEC) and FIT data of the following devices (CYPRESS SEMICONDUCTOR):
CY25811SXIT, CY25811SXCT

Why might the output be inverted?
A board using CY2308SXI-1 seems to be inverting the output on bypass mode (S2=1; S1 =0).
But according to the data sheet the output is only inverted from the reference clock for the -2 or -3 devices.
Note: R57 not installed

Show LessHello,
The Cypress CY22801 is listed on the Infineon website as an "active and preferred" device, and I would like to design a product using it. The field programming tool listed in the datasheet however is obsolete and no longer available.
What hardware is currently available to perform field programming of this device in prototype quantities?
Thanks.

Like Ripple or PSRR number?
What is IC internal circuit to rejection power noise?
Show LessHi. Infineon
in the website(Infineon Technologies😞 I can't downloard the clockwizard2.1 install software. whether have you newly clock software, we use the CY27410FLTXI PN, need the software to operate.
thanks
