Electrical Characteristics - AC
Unless stated otherwise, VDD = 3.3 V ±5%, Ambient Temperature -40 to +85
° C, CL= 15 pF
1CLKOUT and SMBus pins are tri-stated when PWRDN/ is asserted. CLKOUT is driven differential when PWRDN/ is
de-asserted unless its already disabled.
2The period is when VDD equals its typical VDD condition.
Measurement Diagrams
Measurement diagram for duty cycle and jitter.
Current Reference Source (Iref)
If board target trace impedance (Z) is 50
, then Rr = 475 (1%), providing IREF of 2.32 mA, output current (IOH) is equal to
6*IREF.
