Bharath,
The LMX2594 can generate sysref or also be used as a repeater for Sysref. The LMK04828 I believe can do the same.
Both the LMX2594 and LMK04828 can be used as a repeater to echo sysref on an input pin, or a generator to create Sysref pulses…
Bert,
For a single-ended termination, consider doing something like we do for reference design TIDA-01410. For the side you use, put the pull-up, and AC coupling cap. For the unused side, you also need the pull-up to Vcc, and AC coupling cap. Then…
Toshiro-san,
If the outputs are the same frequency and from the same chip, you theoretically should not need this filtering. However, I would err on the conservative side and still put this for fear of frequency pulling effects.
I say this because…
Part Number: LMX2594 Other Parts Discussed in Thread: TIDA-01410 I have several questions regarding the operation of the LMX2594. We'd like to generate three tones (1.5G, 2.5G and 7.5G), synchronize them, then adjust their phase individually. With a reference…
David,
The output power reported is Single-Ended and is what we believe is at the pin of the part.
To get these graphs, we used a board with the shortest possible trace (used reference design TIDA-01410) that was routed for single-ended outputs…
Sofiane,
Yes, for the first approach, you can do as you say. Realize that the board may have some losses due to the trace and SMA, but the inductor pull-up followed by the resistive pad is a good way to go. If you do the resistive pad with resistors…
Part Number: LMX2594 Other Parts Discussed in Thread: TIDA-01410 I am having difficulty achieving desired phase settings. Here is a description of the specific tests and results.
In all cases, Fosc = 100 MHz, Fpd = 50 MHz, PLL_NUM = 0, PFD_DLY_SEL …
Hi Binal,
Here is a document that explains the output power numbers in the datasheet in relation to measurements on the EVM.

Regarding current draw, the output power settings is typically the tunable and most current…
Hi,

I wrote this document that goes into depth on these outputs. In includes a section on output impedance.
