CDCE6214-Q1: CDCE6214-Q1 mode of operations quires

Part Number: CDCE6214-Q1

Hi Team,
 
We are planning to use the CDCE6214-Q1 part in our design.
 
1. Could you please clarify whether the EEPROM can be programmed using the Serial Interface Mode to set different output frequencies, or if this programming capability is only applicable in Fall-back Mode?
 
2. To set the fall-back mode, does one of the two pins, REFSEL or HW_SW_CTRL, need to be floating?
 
3. Additionally i want to know what functions we can perform in Serial interface mode?

4. When operating in PIN mode, each GPIO pin acts as an individual Enable or Disable control for its corresponding output. Could you please clarify the state (high or low) required on the GPIO pin to enable the output?
 
5. Additionally, I would like to know how to set the OE (Global) pin to enable or disable all differential outputs simultaneously.

    Hi Praven,

    1- Programming can only be done in fall back mode 

    2- Both need to be floating 

    3- Per section 7.4.1.3 Serial Interface Mode of the datasheet: "In serial interface mode, pins 12 and 19 are configured as an I2C interface."

    4-  Refer to section 7.3.5 Control Pins of the datasheet and below is the pin map description showing the function and state of the pins 

    5- Section 7.3.3.3 Global and Individual Output Enable goes over the details. Please note that In pin mode, the pins 12 and 19 are input pins which act as individual output enable pins. Together with pins 11 and 20, this allows for one output enable pin per output channel.

    Please also refer to the register map for setting the register bits accordingly 

    Best,

    Sandra
