CDCLVP1208: RE:CDCLVP1208 Output Sync options

Part Number: CDCLVP1208
Other Parts Discussed in Thread: LMK04832

Dear Team,

 In our design we are using multiple ADC’s , for clock feeding to the ADC’s from the single reference clock using CDCLVP1208 Buffer we will generate the multiple clock and we will feed to the ADC’s

 While using different ADC’s clock signal should be synced, clock buffer there is no output sync option in the buffer. kindly suggest whether we can use CDCLVP1208 buffer or please provide any other recommended part for our design.

 ADC Part Number we are using in our design - ADC16V130CISQ/NOPB

 Thanks

Naveen P

  • Hello Naveen,

    Since the CDCLVP1208 doesn't have any dividers, you don't need to SYNC it.  According to the datasheet there is a max propagation delay of 450 ps with a part-to-part skew max of 125 ps.

    I searched SYNC in the ADC16V130CISQ, didn't see any need to sync that divider... however if you did need to sync, consider the LMK04832 which can be used as clock distribution in addition to using an output from SYSREF to provide a SYNC signal.
