Part Number: CDCE72010 Other Parts Discussed in Thread: ADC08D1500 Hi sir,
I want to use CDCE72010 provide clock to ADC08D1500.
is it possible?
The maximum clock frequency that CDCE72010 can output 1.5G(LVPECL).
The clock requirement of ADC08D1500…
Hi Jim! Sorry for not immediately answering, I was busy. I put aside this board with ADC12D1600 ADC. I have a board with ADC ADC08D1500 and FPGA. I decided to check correctly I accept the data from the ADC. This ADC is similar to the ADC12D1600, it is…
Hi Yaita-san
During calibration, the ADC08D500 (similar for ADC08D1000, ADC08D1500, ADC08500, ADC081000 and ADC081500) LVDS DCLK output stops and the DATA outputs are static (logic 0 I believe). DCLK and DATA operation resumes when calibration is complete…
Hi Shinichi
In the ADC08D1000, ADC08D500 and ADC08D1500, if the On-Command calibration is done when the ADC is set in Auto DES Mode, the internal clock duty cycle correction circuitry can become unstable and the internal clock will stop. The only way…
Other Parts Discussed in Thread: ADC08D1500 , LMK04031 , LMK04001 , LMK04011 Hi,
There are two voltage levels available, assume for example they are using the higher voltage setting. In the digital output characteristics section, the data sheet quotes…
Hi Reza
The DCLK_RST feature will function with an asynchronous input, but because setup and hold is not guaranteed there will be +/- 1 ADC clock uncertainty for the capture of DCLK_RST into each ADC.
To ensure all ADCs capture DCLK_RST on the same…
Hi David
Sorry about the delay responding. The LMK01020 (LVPECL outputs) can provide 1:4 distribution of the LMX2541 output at 1.5 GHz. Another option would be using the LMK04808 operating at 3 GHz internally dividing down to 1.5 GHz for 4 outputs.…
Hi Bugra
The ADC08D500 device does not include an output data test pattern. There is a pin compatible device which does have that feature, the ADC08D1020.
It is possible to design a board that can accommodate both devices, please see this document…
Hi jlin
I have a few other comments related to the ADC operation and usage.
Since you will be using this converter in DES (Dual Edge Sampling) mode please note that you must return the device to non-DES mode whenever an on-command calibration is required…
