CDCVF2310-EP: Radiation data for clock buffer

Sudarsan Srinivasa
Prodigy 30 points
Part Number: CDCVF2310-EP
Other Parts Discussed in Thread: CDCLVP111-SP, CDCM7005-SP, LMK04832-SEP, LMK04832-SP, LMK04832

Tool/software:

Hi, 

Is there any radiation test data available for this clock buffer? TID, SEE etc?

We're looking for a radiation tolerant LVCMOS fanout clock buffer and the space qualified part (CDCLVP111-SP) cannot fanout LVCMOS. 

Thanks!

Cheers,

SR

    Hi SR, 
    Please note EP or enhanced plastic parts juts go through extra qualification testing and have extended temp range -55 to 125degC in this case but don't have any radiation hardening built in. 
    If you want LVCMOS outputs you're limited to LMK04832-SP, LMK04832-SEP, CDCM7005-SP. 

    LMK04832 Hi-Rel parts will need to be programmed to operate as a buffer. 
    What is your timeline? We currently have an upcoming space buffer that may meet your requirements. 

    Here is a thread below on using CDCM7005-SP as a buffer as their is some setup requirement. 
    (10) can i use the CDCM7005 as a 1:10 lvcmos buffer - Clock & timing forum - Clock & timing - TI E2E support forums

    Best regards,

    Hi Vicente, 

    Thanks for the quick response. We're looking for a clock buffer in a plastic package (preferably SEP, but SP is also acceptable) with min. 8 outputs capable of distributing 50MHz 3.3V level LVCMOS signals.

    We specifically do not want to use a ceramic package because our EMS partner is not experienced in handling such parts (so the CDCM7005-SP is out of the question).

    Our timeline is to create engineering samples by the end of the year 2025 and go into production in Q2/Q3 2026. Can you tell me if this is approximately the timeline you're also looking at for the new buffer? 

    Thanks!

    Cheers,

    SR

    Hello Sudarasan, 
    Understood. LMK0432-SP is out of the equation then - it has a ceramic package. 
    The LMK04832SEP on the other hand is a plastic package. 

    The new space component could meet your timeline. Let's take this conversation offline to talk about dates and requirements. 
    Please email me at v-floresprado@ti.com ; I will loop in the corresponding people. 

    Best regards, 

    Vicente
