Other Parts Discussed in Thread: CDCM6208V1, CDCM6208

Hi members.

This is BEN.
Please advice for me.
My customer select  CDCM6208V1.


It is use to  I2C mode. 
But I2C control  does not work for access sign.
Do you have any notes  or any problems?
He has set the following.
  ・SI MODE[1:0]=01
  ・AD0 is pull down toGND
     ・AD1 is pull  up  to  DVDD
     ・Slave Address: 1010110
     ・RESETN  is High
     ・PDN is  High

Best regard.
BEN.

  • Hi Ben,

    These settings look OK. Please ask the customer to ensure that the timing information on Page 70 of the CDCM6208 datasheet is followed. The usual suspect for incorrect programming is slow rise time for the signals on the I2C bus. Please ensure that the pull-up resistors are sized appropriately to guarantee rise time < 1000ns (STANDARD MODE) and < 300ns (FAST MODE)
