Part Number: LMX2571 Tool/software: Hi Team,
1. For the 5V power supply of Vcc, if the power supply voltage is lower than 5V, for example, around 4.3V, can the charge pump work normally? Which spec will be affected?
2. In external VCO mode, when switching…
Part Number: LMX2571 Hi there!!
I am going to use LMX2571 to make 100MHz from the source (10MHz).
And I will use the internal VCO. And I don't need Fast Lock function.
Since I only need 100MHz output.
In this case, do I leave FLOUT1, FLOUT2 open like…
Part Number: LMX2571 Tool/software: Hi Team,
Customer encountered a problem with the charge pump when using LMX2571. The specific situation is as follows: Register configuration process:
1. First configure all registers, and configure the pump current…
Part Number: LMX2571 Is there an equation or appnote that describes optimal tuning for the RFout network for open drain mode (LC pullup tuning network)
I noticed that a completely different circuit is used on your reference design (evaluation board) for…
Part Number: LMX2571 Other Parts Discussed in Thread: SN74LVC2G14 I have noticed in the datasheet of 2015, page 11 following points to remember:
When using the Multiplier (MULT > 1), there are some points to remember: • The Multiplier must be greater…
Part Number: LMX2571 Other Parts Discussed in Thread: LMX2572 Hi,
According to the datasheet, "The switch can also be configured as a 1:2 fanout buffer, providing the signal on both outputs at the same time."
What is the time difference between…
Hello Vicente,
Thanks again for the help in solving a complex issue. To close the loop, I've marked your first response as the correct one as the issue was on the OSCIN pin.
For anyone else reading, it was not straight forward though: My CMOS oscillator…
Part Number: LMX2571 Hi,
It's not entirely clear from the datasheet. Can RFoutRX and RFoutTX be configured to output different frequencies simultaneously? Section 7.3.10 states that the "active port" can be switched as well as the frequency. What does…
Part Number: LMX2571 Other Parts Discussed in Thread: CODELOADER , LMX2571 is used in synthesizer mode with internal VCO in our application.
Using Codeloader to config the LMX2571, the Auto Reload with Changes has been ticked.
- If PLL_R_PRE_F1 = 1, registers…
Part Number: LMX2571 Hi Team,
I would like to know FSK input pin condition while POWERDOWN.
I'm planning to share I2S signal with LMX2571 and other devices.
When LMX2571 is in POWERDOWN mode, is the voltage of I2S signal droped by LMX2571?
In addition…
