Test Conditions/Comments
Does not include power dissipated in external resistors; all
LVPECL outputs terminated with 50 Ω to V
outputs have 10 pF capacitive loading; VS_DRV = 3.3 V
No clock; no programming; default register values
f
output and output divider enabled; zero delay off
f
LVPECL output and output divider enabled; zero delay off
PLL on; VCO divider = 2; all channel dividers on; 12 LVPECL
outputs @ 125 MHz; zero delay on
PD pin pulled low; does not include power dissipated in
termination resistors
PD pin pulled low; PLL power-down, 0x010[1:0] = 01b;
power-down SYNC, 0x230[2] = 1b; power-down distribution
PLL operating; typical closed-loop configuration
Power delta when a function is enabled/disabled
VCO divider not used
Delta between reference input off and differential reference
input mode
Delta between reference inputs off and one singled-ended
reference enabled; double this number if both REF1 and REF2
are powered up
PLL off to PLL on, normal operation; no reference enabled
No LVPECL output on to one LVPECL output on; channel divider
set to 1
Second LVPECL output turned on, same channel
No CMOS output on to one CMOS output on; channel divider
set to 1; f
Additional CMOS outputs within the same channel turned on
Delta between divider bypassed (divide-by-1) and divide-by-2 to
divide-by-32
reference, 0x230[1] = 1b
