Part Number: LMX2531 Hello,
My use case is as follows:
1. I perform the whole colds start procedure as described in the LMX2531 Data Sheet, chapter 8.6.1.1. Before sending any data over uWire, I set the CE pin high. The delay between sending the first…

We are having issues reflowing the LMX2531LQ1500E. Following recommended guidelines has yielded no better results than before. Like previous post regarding this issue ( https://e2e.ti.com/support/clock-and-timing/f/48/t/649000 ), we…
Part Number: LMX2531 Hi,
I'd like to ask you the reference schematic of LMX2531 like schematic of evaluation board user's guide. There is a reference schematic of LMX2501 in evaluation board user's guide. Please share it with me.
Regards,
Part Number: LMX2531 Hi,
It says that "LE can be kept high if bit R5[23] is changed to 0 (from its default value of 1). If this bit is changed, then the operation of the part is not ensured because it is not tested under these conditions" in page 19 of…
Part Number: LMX2531 Hello,
The datasheet says “1.8-V MICROWIRE Support”.
But there is no MICROWIRE DO pin.
LMX2531 does not have DO pin?
Users can not read register contents?
Best regards,
K.Hirano
Part Number: LMX2531 Hello,
At cold start, after all VCCDIG, VCCVCO, VCCBUF, VCCPLL and CE get 3.3V and before the initialization sequence (1 st R5 INIT 1 access), what OUTPUT TYPE could Ftest/LD pin be in the table 11 of the datasheet?
Is the OUTPUT…
Part Number: LMX2531 Other Parts Discussed in Thread: TICSPRO-SW Dear Team,
We have observed in multiple boards the below scenario: Even though the Output from LMX2531 IC is not available, Lock status shows high. The lock status is high even in normal…
Part Number: LMX2531 Other Parts Discussed in Thread: LMX2541 , LMX2581 , LMX2572 Dear expert,
May I have your comments about below spec?
- Similar with LMX2531
- -90dBc/Hz at 10KHz (typ.). -83dBc/Hz is not good enough for customer's requirement.
…
Part Number: LMX2531 Sir,
We recently measured the tuning voltage of different frequencies when the synthesizer is settle and the result is shown in the attachment.
The figure imply that LMX2531 have negative Kvco in each frequency band.
Would you pls…
Part Number: LMX2531 I have a customer who purchased the LMX2531LQ1570E eval board. However, they are now planning to use the LMX2531LQ1515E frequency range instead.
The GND pads on these two package options are different--specifically, the DAP pin.
Is…
