Hello,
I will request an status from our software team on when to expect an update.
There are multiple considerations when deciding a loop bandwidth. But in general there is an ideal loop bandwidth that minimizes the jitter and this depends on the noise…
Part Number: LMK04808 Tool/software: Hi, I'm going to use the LMK04808 Low-Noise Clock Jitter Cleaner device by the MSP430 SPI controller. I have seen the datasheet of LMK04808 and found the register map with default values. My intention is that I…
Part Number: MSP430F5342 Tool/software: Hi Team,
We are using the parts MSP430F5342IRGZR and LMK04808BISQE/NOPB from TI in our new design. And we need to configure the LMK clock using MSP430 via the SPI interfaces available in both the devices.
As per…
Hi Will
Thanks for your experiment. I keep asking questions because I think your experiment and my requirements are different. I have been thinking about the conditions under which you experimented. I'm guessing you've probably experimented with PD_OSCin…
Part Number: LMK04808 Hello, we are trying to generate a 500 MHz signal with the LMK04808 Dual-Loop configuration. However, we are not able to get the PLL1 to lock (PLL2 is locking). The reference input (CLKin1) is a 125 MHz clock signal. The VCO we are…
Hi Hima,
if you receiver already has internal bias, use AC couple.
Since your common mode is only 700mV, you should also set LMK04808 LVPECL output to 700mV or 1200mV option.
Part Number: LMK04808 Other Parts Discussed in Thread: LMK05318BEVM , USB2ANY , CODELOADER I have created a custom LMK04808B board and broke out the uWire pins to program externally. I have it configured to use: 15k series resistor and 27k pull down resistor…
Part Number: LMK04808 In the scenario we assume that we have already powered up and programmed the LMK04808. When we try to re-program through MICROwire (just to send one register), how long does it take to process? Is there a specification for this process…
Part Number: LMK04808 Hi team,
What does the reserved bit in R31 mean?
The issue is PLL1 loses lock. We did 2 tests.
1. compare all the register readback, only R31 is different. please check the results below:
R0:0x140300 R1:0x140181 R2:0x140182 R3:0x14…
