Part Number: LMK00338EVM Hi,
We're using the LMK00338EVM with a differential input. We are able to see a clean output when using the internally generated clk, but we are not able to see an output after startup when using our input signal.
We are using…
Part Number: LMK00338EVM Hello,
I have a system that certain pcie cards are present and sometimes they are not. With the clock buffer, it is not possible to select the outputs to be wired induvidually. If the traces are routed with DC coupling, would…
Part Number: LMK00334 Other Parts Discussed in Thread: LMK00338EVM I want to input DC-coupled LVDS clock to the LMK00334. LMK00338EVM reccomends to implements series capatcitors following the 100-Ω termination like (A) . However, I want to reduce the…
Hi John,
Please request access to these documents for the DS160PT801X16EVM using the link here .
Additionally, the LMK00338EVM (EVM for the LMK00334) may be of helpful reference to you as well
Best, David
Hi Gavin,
A1. I just measured it on LMK00338EVM. CLKinX bias = 1.08V, CLKinX* bias = 1.35V . For this measurement, there is no input/output using the default EVM assembly.
A2. Yes, these unused pins can be left floating
Kind regards, Lane
Hi Anne,
Sorry for the delay. The datasheet suggests 18-20pF XTAL load capacitance. I tested the default LMK00338EVM (where the XTAL circuit image was found), and it functions without issue.
Kind regards, Lane
Part Number: LMK00338 Hi,
On the top page of the datasheet, there is the description of "Additive RMS Phase Jitter for PCIe Gen3 at 100 MHz :30 fs RMS (Typical)". Does it mean that you have history that LMK00338EVM passed PCIe Gen 3 compliance test…
Part Number: TMUXHS4412 Other Parts Discussed in Thread: LMK00338EVM Hi,
I am designing a motherboard which requires 2 PCIeX4 connector, the standard PCIex4 connector(SAMTEC PCIE-064-02-S-D-RA) and M.2 KeyM connector(Molex 1-2199230-6). but my CPU has…
