Tool/software:
Good afternoon,
I'm looking at using the SYNC mode feature on the LMX2694-SEP and am wondering how the SYNC Pin Timing Characteristics for Category 3 SYNC given in Table 7-13 were selected? Of the three given parameters, I'm most interested in knowing how 40MHz was determined as the maximum allowable input reference frequency for Category 3 SYNC. The flowchart decision immediately before Category 3 (f_osc ≤ 50 MHz) does not align perfectly with the stated max input reference frequency of 40MHz, so I was wondering if a given reference frequency between 40MHz and 50MHz could still enable Category 3 SYNC performance.
Best,
Jonathan
