I am trying to use the HCSL output with this clock generator.
The HCSL output specification in the datasheet stated the following:
Let me ask you a few questions about this.
1. There is no single-ended VOH or VOL listed here. What are the HIGH and LOW voltages at single-ended?
2. I understand that the differential voltage amplitude is 300mV (150mV-(-150mV)). Is this correct?
3. If my understanding in 2. is correct, does this voltage meet the HCSL specification?
(For example, the HCSL input specification for CY2DP1502 specifies a differential voltage of 400mV at minimum.)
Please provide an answer.
I'm using the CY22801 clock synthesiser on a project with a Xilinx Zynq SoC and Yocto.
I can't find an existing IIO driver in the latest release of the Linux Kernel:
Is there a suitable IIO driver that I can use, please?
Failing that, is there a C driver library available that I could integrate into IIO?
Can I use this crystal for CY27410 ?

Is there any replacement (either drop-in or closest) available for the part “CY7B994V-2BBI” or “CY7B994V-2BBIT”Show Less
While using the program provided - ClockWizard 2.1 to configure the CY27410, it was noted that the register addresses, e.g. 0x000000, 0x0186A0, are 24 bits long listed in the memory map of the results tab. This seems to contradict the information on I2C communication found in the datasheet.
On page 8 of 30 in Document Number: 001-89074 Rev. *M, it is documented that "A valid write operation must have a full 8-bit register." Furthermore, on page 9 of 30 on the same document, the following is noted: "... the CY27410 issues an acknowledge and transmits the 8-bit word."
It is clear that the datasheet of the CY27410 states that it reads and writes 8-bit words.
My question is then, why does the program ClockWizard 2.1 suggest that the addresses are 24 bits long, identified by the hex addresses listed in the results tab in the memory map section.Show Less
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.
I am trying to read and program the CY22393FXC, i need to get a programmer that is able to do those operations but im not sure which one will be the best for my needs. Please guide me on good programmers for this device.
I would like to use CY27410 with internal POR, and omit external reset.
Can I leave XRES pin to open?
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#M609Show Less
in our design we are using the obsolete CY7B992-7JI. Is a replacement available?
