TLK2711-SP: Icc Datasheet Specs

Sean Rauchfuss
Intellectual 865 points
Part Number: TLK2711-SP

Posting for a customer.  For the TLK2711-SP, please help to address the following questions related to the Icc spec.

 

From the Datasheet: http://www.ti.com/lit/ds/symlink/tlk2711-sp.pdf page 8 table 7.3.

 

VDD:  Voltage supply spec’d at 2.5 +/-5%

  • What is the spec for VDDA? 
  • Can this be relaxed, as it is specified to be L-C decoupled from VDD supply, and will be lower on average.

 

Icc: Supply current is 110 mA nominal @ 1.6 GHz.

  • What is a min & Max spec for this current?  Is this at 25 C, or over the MIL temp range?
  • What is the split in current between VDD and VDDA pins?
  • If not a spec, can you provide any typical data for Icc(Vdd) and Icc(Vdda)?
  • What is the dependence of Icc on VDD Supply voltage? (Linear, or?)
  • What is the dependence of Icc on Temperature?

    Hi Sean,

    The applications engineer who is familiar with this device returns to the office next Monday.  He will try to address your questions upon his return.

    Thanks

    Sean,
    ICC does not have a test limit. However, max power is a specification and production tested.
    VDDA is ~30 to 40% of total current/power.
    The variation of ICC across temperature is minimal with slight increase with increasing temperature (about 5% increase from -55 to 125 based on characterization lot).
    I do not have good data on VCC relationship to ICC, as test data is based on worst case only. I would speculate a predominately linear relationship.

    Regards,
    Wade
