In a PCIe Gen4 system, using "common clock architecture", the device (EP) REFCLK is driven from a host (RC) located in a FPGA, which is synced to another PCIe host (The clock generator is not able to be used here). If this device REFCLK is jittering, can we apply a jitter attenuator to it to meet PCIe Gen4 requirement? I found so many jitter attenuator chips in Silicon Labs website, but not clear which one is good for doing the work. Please help to give your advises.
We are interested in the " 10-Channel, Any-Frequency, Any-Output Jitter Attenuator/ Clock Multiplier" , reference : "" SI5344B-D-GM"". and we need information about :
On my Si5338C the outputs are not active after successful programming according Fig. 9 of the Si5338.pdf (Rev. 1.4) and using the header file generated by the Clockbuilder.
Setup: Clock source = 25 MHz Crystal, outputs 0..2 active (100/125/100MHz, all LVDS 1.8V). Core VDD / I2C Voltage: 3.3V.
Status LOS_CLKIN, PLL_LOL, SYS_CAL is ok.

Successfully ran Si5338 (U700) config
Surprisingly, if I use the Clock Builder Rev. 6.5 (by patching the I2C signals from the SI5338_EVB to my board) the SI5338C outputs are working as expected (same setting as used for header file generation)
The only what I had found, the Clock Builder generated header file has an inconsistency to the SI5338-RM (Rev. 1.3). According the manual the register 42, Bit 5 must set to "1", but the generated header file set it to "0" ({ 42,0x00,0xFF},).
From the divider ranges specified, and the VCO frequency, the SI5340 should be able to produce output frequencies lower than 100Hz, For example, VCO 14GHz, N divider 1000,R divider 14000000, should produce 1Hz. These are within the specified range for N ( 10 to 4095) and R ( 2 to 2^25 - 2)
the Si5341 Rev D Family Reference Manual Rev 1.1 shows conflicting information about the default CMOS output polarity.
The text of chapter 6.3.7 claims the default is "opposite polarity (complementary)" while table 6.6 in the same chapter states "both in phase (default)".
I want to create a jitter attenuated clock from a recovered clock coming from FPGA. ( for SDI pass through application) . I found that SI5328 do the job I want. But I want to handle 4 individual SDI channels. So I need 4 jitter clean clocks. Instead of using 4 units of si5328 is there any single IC solution ?
I am new to these parts, and cannot find a description of the differences between parts with fractional/integer synthesis, and only integer synthesis. All data sheets return a data sheet for the D device, and there is no block diagram which shows the difference in the dividers for the different types. I have been using the Analog Devices AD9578 in a number of designs, however the SI5340, although similar, looks superior, due to the very high VCO frequency, the fractional synthesis of the PLL, and the fractional divider following this. I assume that in the part variant without fractional synthesis, there is a restriction on one of these dividers.
If I use these parts, I will need to develop my own software to calculate the optimum dividers for any output frequency, as I need flexibility of output frequencies.
Could you please point me to documentation which further describes the devices. I have tried the Clock builder pro software, however this is only really suitable for the design of fixed frequency applications.
we want to use the Si5351 Device in our new project. The requirements of the design is that all output clocks must be synchron by the phase (4x 120 MHz and 1x 60 MHz).
Is this possible with this device (Si5351A +crystal oscillator ) => Do the Multi-Synth 0...7 work phase
When using this website, I found that the startup frequency of this part is 297MHz.
When I use it to program in your Programmable Oscillator Calculator Software (ver 6.0.1.0), I get certain register values, and when programming the value, the generated clock is with in the range of it but not exact.
For example, If i program 297Mhz as startup and I require 75MHz, the generated clock is 80MHz. And when changing the divider value I get various clocks but not the one clock that I require. Is this expected? Is there any way to make it more perfect? Am I missing something?

Manually Generating an Si5341 Register Map
Hi,
I am trying to manually generate register setting for Si5341, but can't find any document.
I only found a document that works for Si5351(https://www.silabs.com/documents/public/application-notes/AN619.pdf).
Anyone know whether there is similar document for Si5341?
Thanks,
H.J.
Si5332 on custom board not programmable with CBpro Dongle
Hello,
i have a custom board with an un-programmed Si5332 soldered to it.
Writing the design to the device with CB V2.29 is working without problems via I2C and CBpro Field Programmer.
But programming the device is refused with the error message: Not enough NVM space available to burn plan.
Checking the NVM state gives: 137 frames used, 0 bytes available to burn, see attachement.
Are there special considerations I have to take to perform a NVM program?
Thanks

Looking for PCIe Gen4 clock jitter attenuator (chip/design), anyone could help?
Hi,
In a PCIe Gen4 system, using "common clock architecture", the device (EP) REFCLK is driven from a host (RC) located in a FPGA, which is synced to another PCIe host (The clock generator is not able to be used here). If this device REFCLK is jittering, can we apply a jitter attenuator to it to meet PCIe Gen4 requirement? I found so many jitter attenuator chips in Silicon Labs website, but not clear which one is good for doing the work. Please help to give your advises.
Thanks.

How to use clockbuilder pro store profile in Si5332
Si5381 achieve 8 clock signals with 2.10G and a clock signal of about 200MHZ
Hello:
Which mode is the Si5381 in when it can generate the clock signal with a frequency 2.106514285G (14.7456G/7=2.106514285G).
I want to achieve 8 clock signals with 2.10G and a clock signal of about 200MHZ.
Can the Si5381 implement the above clock signal?
SI5338C no output / Clock Builder problem
Hi,
On my Si5338C the outputs are not active after successful programming according Fig. 9 of the Si5338.pdf (Rev. 1.4) and using the header file generated by the Clockbuilder.
Setup: Clock source = 25 MHz Crystal, outputs 0..2 active (100/125/100MHz, all LVDS 1.8V). Core VDD / I2C Voltage: 3.3V.
Status LOS_CLKIN, PLL_LOL, SYS_CAL is ok.
Here is the log of the I2C communication:
Surprisingly, if I use the Clock Builder Rev. 6.5 (by patching the I2C signals from the SI5338_EVB to my board) the SI5338C outputs are working as expected (same setting as used for header file generation)
The only what I had found, the Clock Builder generated header file has an inconsistency to the SI5338-RM (Rev. 1.3). According the manual the register 42, Bit 5 must set to "1", but the generated header file set it to "0" ({ 42,0x00,0xFF},).
Any ideas how to get my outputs running?
Many thanks, Alex
