Other Parts Discussed in Thread: LMX2430 Hi
I have a question about LMX2430.
We will order to reduce the power consumption, to be used only IF circuit.
If you do not use the RF circuit, please tell me the terminal processing related to RF.
Is…
Other Parts Discussed in Thread: LMX2430 Hello,
I have gotten one question about LMX2430 as below from my customer.
Q) Revcovery time
The question is about the recovery time when LMX2430 is from power-off to power-on.
That is to say,
1)Power…
Hello,
Could you please let me know the recommended register setting when RF_PD=1 ? <Reg : R0 > 21 : RF_RST -> Please let me know recommended setting, if there is. 20 : RF_CPT -> Please let me know recommended setting, if there is. 19 : RF_CPG -> Please…
Other Parts Discussed in Thread: LMX2430 , LMX2470 Hello, Could you please let me know the VCO tuning voltage range(VCPout range) of LMX2430/2433/2470? We would like to these device with frequency range of 1636.2～1671.6MHz with 300kHz step. Ref in is…
Part Number: LMX2491 Other Parts Discussed in Thread: LMX2430 , LMX2571 , LMX2485E What limits lower frequencies of LMX2491 Fin input? Can it operate at 400MHz?
What PLL ICs can operate on lower frequencies?
Hi There,
LMX2491 or LMX2571 are recommended as they support 5V charge pump.
LMX2430 is also recommended for lower cost but an active loop filter is required to boost the Vtune to 5V.
Hi Daniel,
I understand that the datasheet will be revised again.
Due to our internal flow, we cannot approve the adoption of the device if the datasheet remains at 5V, so could you please make the corrections to this section first and send us the…
Part Number: LMX2433EVAL Other Parts Discussed in Thread: LMX2433 , LMX2430 , USB2ANY , LMX2581 , CODELOADER , USB2ANY-UWIRE I can´t communicate the computer with the PLL.
I am using a HPA665-001 to program LMX2433EVAL board. Between both is SV600857…
Part Number: LMX2571 Other Parts Discussed in Thread: LMX2430 Hi team,
My customer is looking for a PLL synthesizer. The phase noise spec and block diagram is as below figure.
Originally, they used ADF4002 and ADF4150 for old design. But, it looks…
Ay,
Yes, we do some testing for these pins, but no we don't have input impedance for this device. We test for sensitivity and continuity.
On the LMX2430, it is lower frequency, so this measurement was a little easier.
So in general, it is intended…
