Table 6. AC Characteristics: VDD = 3.0 V, -40° C < TA < 85° C, unless otherwise specified
Note 1:
Fclk is verified during the functional pattern test. Serial programming sections of the functional pattern are clocked at 10 MHz to verify Fclk
specification.
Note 2:
CMOS logic levels can be used to drive reference input if DC coupled. Voltage input needs to be a minimum of 0.5 Vp-p. For optimum
phase noise performance, the reference input falling edge rate should be faster than 80mV/ns.
Note 3:
Parameter is guaranteed through characterization only and is not tested.
