AWR2243: CLKM Grounding

robert hoff

Part Number: AWR2243
Other Parts Discussed in Thread: MMWCAS-RF-EVM

In the datasheet for the AWR2243, it states that when using an external clock, "the signal is fed to the CLKP pin only; CLKM is grounded."

Should CLKM be grounded with a resistor in series?

Thanks,

Robert

Hi Robert,

XTALM can be directly shorted to GND or grounded through a 0-ohm resistor. On the MMWCAS-RF-EVM, a resistor is used just to allow for swapping between XTAL and single-ended mode in some cases.

Thank you,

-Randy
