NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
6. 10 MHz is the maximum frequency to load the feedback divide registers. S_CLOCK can be switched at higher frequencies when used as
a test clock in TEST_MODE 6.
7. FOUT/FOUT and TEST outputs are terminated through a 50 W resistor to VCC - 2.0 V.
8. Maximum frequency on FREF_EXT is a function of setting the appropriate M counter value, 160 v M v 511, for the VCO to operate within
the valid range of 400 MHz v fVCO v 800 MHz. (See Table 5)
