CDCE6214: PLL IC similar to XC25BS9 is needed

Part Number: CDCE6214
Other Parts Discussed in Thread: CDCE62002, CDCE913, LMX2571

Hi team, 

My customer has been using XC25BS8 as a PLL IC for 384 multiplication. Do we have any devices that is similar to this device?

Best regards,

    Hello,

    We have an assortment of programmable clock generator options, such as the CDCE62002 or the CDCE913. I will see if we have a fixed-multiplier part, and get back to you with another recommendation (if any) by tomorrow.

    Thanks,

    Kadeem

    Hello,

    We do not have an IC that functions as a PLL IC for 384x multiplication that does not require EEPROM programming. The closest that we offer is the CDCE913 or the CDCE62002, which will require register programming to achieve this multiplication.

    If you can let me know via email what frequency is used for the input, I can make an accurate recommendation.

    Thanks,

    Kadeem

    Hi Kadeem-san,

    Thank you for your reply. I understood your recommendations. As a feedback from the customer, 1 input and 1 output of PLL is enough. no more 2 or 3 outputs. Also, input frequency is several 10 kHz, and output frequency is 800MHz. The application is wireless mic which uses FSK modultaion.

    Do we have such a PLL?

    Yamamoyo-san,

    To be clear, you are looking for a PLL that can support an input frequency of 10 kHz, with an output of 800 MHz? I believe that you mentioned that the original device that is currently being used is a 384x multiplier PLL with an input range of 8 kHz to 36 MHz, and an output range of 1 MHz to 100 MHz. 

    We promote the LMX2571 for FSK designs, but this device has a minimum input frequency of 1 MHz -  I do not believe that we have anything that can support an input frequency in the 10s of kHz range with a 800 MHz output.

    Thanks,

    Kadeem
