I have one question about ADCLK948's output. I read the datasheet that ADCLK948 can input CML signal. I want to know whether ADCLK948 can output CML signal?
Thanks in advance for your kindly help!
The ADCLK948 can only output LVPECL signals. Please see page 9 of the datasheet `for some recommended output terminations. This also includes a simplified schematic of the output drivers.
If I may add some comments regarding the ADCLK948, keep in mind you can always AC-couple and re-bias the output to CML levels.
Also, CML (like LVPECL) tracks Vdd, and 3.3V LVPECL will have a DC common-mode voltage compatible with 2.5 V CML, so the DC-level compatibility depends on Vdd of the input receiver.
In addition, the majority of input receivers on the market today have their own internal DC-biasing, so the number of cases where one must re-bias the DC-level is decreasing.
