Dear team,

I am currently using the LMK03318 and facing an issue where there is no output. 

I have attached the configuration file and Pin connection diagram for the LMK03318.

I am using TICSPro for the register settings…

Hi,

I am evaluating the LMK03318 using TI's EVM board. I measured the output waveforms on a Scope. I have a couple of questions:

1. The 1 GHz output looks more…

Hi,

I have a few more questions re: LMK03318:

• How can I make the differential outputs from an output bank to be in phase when configured as LVCMOS? What register bit do I need to set?
• If I want to use a TCXO (clipped…

Hi,

I have a few questions regarding LMK03318 and the evaluation board:

1. Does VDDO for the clock outputs need to be 1.8V for LVCMOS? Or, will the output be automatically on 1.8V even if VDDO is 3.3V? I plan to have…

Hi,

My question is somewhat related to my previous query:

Hey,

We are having some issues with the LMK03318EVM. We remember it was working a few months ago. But now the clock outputs look strange. In order to debug we are investigating the SECREF output, hence bypassing…

Hi,

I have a test board where I need to check the jitter tolerance of the clock. I am looking for a external lcok source to generate a single ended…

Hi Team

do we have any proper solution for SI52258A?

Dear Team,

The maximum value of LVCMOS input high voltage is VDD_IN.

If an overshoot occurs and exceeds VDD_IN, will this IC stop functioning?

Many Thanks,

Ryo

Hi, I could not find any information on dimensions of the part LMK03318RHST (Package WQFN (RHS)) in the datasheet or website. Please help to get the information.

Hello,

My customer is looking for a low cost clock solution that can receive 30.72MHz TCXO output and multiply it by 2/4 to output 61.44MHz/122.88MHz as below.

Hi

Good day.

I'm third party programmer manufacturer.

I'm developing the algo of CDCE6214-Q1 on our programmer, and customer is Delta. They will program…

Dear Team,

The swing specification for LVPECL that you recommend is 500~1000mV. We have an IC whose specification is 0.4~0.9V Is this output swing adjustable?

Many Thanks,

Hi,

I am using LMK03318 to generate several AC-coupling LVDS clocks to one controller. Right now, two reserved clocks are not useful. Should I disable the two outputs or continuedly to generate clocks from that two output? Which…

HI Support,

1) Is "Export HEX register values" file generated by TICSpro the correct production programming file that should be used to program LMK03318 in production on virgin boards (using onboard I2C bus master for example…

Hi,

I am using the LMK03318 to generate several differential outputs. But the output7 peak to peak swing is always larger than other output. The swing is almost about 2V that…

HI

Are device function parameters and reliability NOT AFFECTED if device would operate driven by LVCMOS 3.3V 25MHz oscillator 50R output impedance connected to the PRIM_P input of LMK03318 configured as shown below:

Thank you, …

HI Support, 

I am using TICSpro to generate configuration file for the LMK03318.

I am trying to come up with PLL filter parameters and failing - please help.

Hey,

We would some help to understand how we can change the base adresse.

We have everything configured and its working as expected - we create a epr which we are using to program the pll.

According to the datasheet we would need…

Hi,

I am using the LMK03318 IBIS for a clock simulation. I am using a simple AC-Coupling way to connect the LMK03318 output to my controller. It has a 1.2V bias Vcm on the controller side.

In the LMK03318 data sheet. The differential…

Hi,

The IC LMK03318rhsr is used in my case to provide 6 output frequencies.The input to this IC is PRIREF_P of 25MHz.
Using TICS Pro software when I try "I2C scan", I can see the device address to be 0x53.
I can read/write…

Hi all!

I have a need to generate two reference frequencies that are locked in sync with each other so I can run my RFSoC and RF transceivers. I need one reference clock at 100MHz and another…

Hello expert,

My customer would like to know the questions below, would you kindly help on it?

1. CLK GEN LMK03318 output_P and output_N can output the same frequency? (single end)
2. can the pin status0 and status1 of LMK03318 be used…

Dear Team,

Do we have any clock gen can meet the spec as below?

one switching two

two-way
