CLOCK OUTPUT ABSOLUTE TIME JITTER (CLOCK GENERATION USING INTERNAL VCO)

Table 8.

Parameter

LVPECL OUTPUT ABSOLUTE TIME JITTER

VCO = 2.46 GHz; LVPECL = 491.52 MHz; PLL LBW = 55 kHz

VCO = 2.46 GHz; LVPECL = 122.88 MHz; PLL LBW = 55 kHz

VCO = 2.46 GHz; LVPECL = 61.44 MHz; PLL LBW = 55 kHz

Min Typ Max Unit Test Conditions/Comments

Application example based on a typical setup

where the reference source is clean, so a wider PLL

loop bandwidth is used; reference = 15.36 MHz;

Test Conditions/Comments

Application example based on a typical

setup where the reference source is jittery,

so a narrower PLL loop bandwidth is used;

reference = 10.0 MHz; R = 20

Integration BW = 12 kHz to 20 MHz

Integration BW = 12 kHz to 20 MHz

Integration BW = 12 kHz to 20 MHz
