Hi team,

In the following case, Which value should I set for REF_SEL?

• Primary input
• Input select through SPI/I2C
• S1_MODE1: 0
  REG4 13b: 1
  REG4 12b: 0

dears,

Does CDCM6208 support 100MHz external clock reference input? could the user configure the output clock via pin control in this condition?

thanks!

Hello Kadeem,

it's a while since your last message.

Do you have any updates for me?

Hi Team

do we have any proper solution for SI52258A?

below is datasheet

Does the CDCM6208 require configuration over I2C on every power up?  Or is there a way to store user configuration over I2C in non-volatile memory? 

Hello, 

I am looking to upgrade my design from using the CDCE72010 to a fractional PLL (with one more more outputs) and was wondering if there are any components you may offer that…

I understand that the phase of the outputs is not controlled in PLL / divider mode, but bypass mode just passes the input through a couple buffers.

I need to know the min and max prop delay…

Hello, 

I am looking for a clocking solution that can support 4-5 fractional pll outputs. The important thing is VCO frequency remains unchanged on the other outputs when one of the outputs is…

Hello TI-support team,

we are using the CDCM620V2 and have a strange behavior with I2C communication.

Means that the CDCM6208 doesn't send an ackknowledge with the first try of read_id after power up in one of our products.

Hi,

      The random jitter given in the CDCM6208 chip manual is only 0.3-0.625ps, while the total fractional jitter is 50ps-220ps. Random jitter and total jitter are not of the same order of magnitude (total jitter TJ >> random jitter…

Hi,

Is there a BOM for this EVM too?

Also interested in the project file instead of gerber itself, if you have it, the gerber file is very hard to understand and there is no schematics that matches the gerber!

We use only secondary input for xtal input and VDD_PRI_REF is left open, and PLL is not locked.

Do we have to connect VDD_PRE_REF to VDD if we don't use the primary clock input?
