CURRENT DELTAS, INDIVIDUAL FUNCTIONS

Current delta when a function is enabled/disabled

from Typical Operation 1

VCO High Performance Mode Enabled

133.5

160.0

Current increase when the VCO mode is changed

from low power mode to high performance mode;

combined current delta of Pin 20 to Pin 23

REFx/REFx Receiver1

2.5

3.3

Current increase when REFB is enabled with a

110.42 MHz reference input; combined current

delta of Pin 3 and Pin 7

Reference Divider

−0.55

−0.39

Delta from bypassing reference divider to using

reference divider = 2; total feedback division

doubled to preserve lock; combined current delta

of Pin 3 and Pin 7

Output Channel

28.4

33.3

One output channel enabled by powering up

M2 divider = 3; D3 and D4 divider = 1; OUT3 and

OUT4 enabled to 800 mV; no internal termination;

associated low-dropout regulators (LDOs)

enabled; includes the current required by the

external termination; both outputs at 1766.72 MHz

Mx Divider On/Off

33.2

36.2

This is the current consumption delta between

an Mx (where x is 0, 1, or 2) divider powered up

and powered down; these dividers are a part of

the RTWO VDD (Pin 20 to Pin 23) power domain

Single Output Plus Associated Channel Divider

(OUT1: Pin 31, OUT2: Pin 35, OUT3: Pin 41,

OUT4: Pin 45)

28.4

33.4

One output driver enabled by powering up the

driver and channel divider (does not include

power on the extra M2 divider); includes the

current required by the external termination;

output = 1766.72 MHz

1 Where x is either A or B.
