CDCE62005 Decoupling

Other Parts Discussed in Thread: CDCE62005

Hi,

I'm using the CDCE62005 clock synthesiser on my board. I'm hooking up the decoupling based on the CDCE62005 evaluation card schematic. However there's a connection to VCCA on Page 13 of the document. VCCA is also mentioned in the datasheet within the Analog Supplies. However, I'm not sure what to connect this to, or what pins to put the two 0.1uF caps next to. I reckon I've got all the other caps going to or near a pin. So what should VCCA connect to and where should these caps be placed?

Thanks

Stuart

    Hi Stuart,

    It looks like we have  wrong information both in the datasheet and EVM user's guide. VCCA  is not part  CDCE62005 device. In the user's guide , VCCA is connected to host controller.

    Please disregard the VCCA information.  We will update both documents soon. Sorry for any inconvenience.

     

    Thanks,
