Hi team,
In TI's 4xAWR2243 cascaded imaging radar reference design TIDEP-01012 reference design | TI.com, the LMK00804B's nCLK input is DC-biased to 0.7V with resistor ladders as below:
the 40M_BUF_ IN_ PRIMAWRY clock is from AWR_1_OSC_CLKOUT, which is a gound to 1.4V swinging square wave.
And I was little confued about the input DC-bias, WHY the Non-inverting differential clock input is not DC biased to 0.7V? Isn't it supposed to both differential clock inputs are DC-biased?
