Rainer,
Thank you for bringing your finding to us!
Indeed, you are right and we had updated the CDCM7005's divider paramerer.
CDCM7005 will not be one of the solutions with your give design criteria with this update.
This update will be available…
Part Number: CDCM7005-SP Can the CDCM7005-SP be used in a distribution mode only (w/o the PLL functionality)?
The idea is to bring ~ 1Ghz into the VCO and provide a divided output (say /8 so we'd see 125MHz at the outputs).
If so, how would we properly…
Other Parts Discussed in Thread: CDCM7005 Hello,
We are having difficulty getting a PLL lock on our CDCM7005. Would it be possible to start by sending our PLL calculations to a TI employee to have them double checked? I can also send our current register…
Other Parts Discussed in Thread: CDCM7005 Hi,
I have couple of questions:
1. Since most of standard VCXO are 491.52Mhz, can you create 160Mhz output from this device by have a 491.52Mhz VCXO and adjusting the delay and various parameters or does the…
Good morning,
I have a question concerning the input impedance seen at the pri_ref (or sec_ref for that matter) input. There is a 150k pull-up resistor on both, but what is after that? Are we driving a FET or BJT stage? Does anyone have input impedance…
Here you go. The values of Cac and Cct will vary depending upon your frequency of operation. Rdc will typically be 50-ohms for most VCO's, but that may also vary.
Hello Tony,
as the CDCM7005 only accepts SPI writes and no SPI read, the bitmap below the block diagram shows the configuration which was sent to the device. Basically like a config inside the silicon while you can reconfigure the block diagram.
Therefore…
Other Parts Discussed in Thread: CDCM7005 I have some basic questions about the CDCM7005:
a) If unused do the YnA and YnB outputs need to be terminated with 150 ohms?
b) I am using the jitter cleaner to lock a 1.2 GHz sine wave VCO. What power level…
Other Parts Discussed in Thread: CDCM7005 Hi,
My customer is using CDCM7005. He wants to use CDCM7005 as 1:3 fanout buffer. Could you let me know Additive jitter at using fanout buffer.
Detail using method of customewr is below.
in reference CLK…
Other Parts Discussed in Thread: CDCM7005 , USB2ANY Hi,
Can USB port be used for CDCM7005 EVM?
It uses SPI.
If customer can use SPI to USB converter, can I get the GUI for USB control?
Thanks.
