1. These inputs are normally wired to V
CC
,GND, or left unconnected (actual threshold voltages vary as a percentage of V
CC
). Inter-
nal termnation resistors hold unconnected inputs at V
CC
/2. If these inputs are switched, the function and timng of the outputs
may glitch and the PLL may require an additional t
LOCK
time before all datasheet limts are achieved.
2. This device should be tested one output at a time, output shorted for less than one second, less than 10% duty cycle. Room
temperature only.
3. Total output current per output pair can be approximated by the following expression that includes device current plus load cur-
rent:
ICCN = [(4 + 0.11F) + [((835-3F)/Z) + (.0022FC)]N] x 1.1
Where:
f = frequency in MHz
C = capacitive load in pF
Z = line impedance in ohms
N = number of loaded outputs; 0, 1, or 2
FC = F *C
4. Total power dissipation per output pair can be approximated by the following expression that includes device power dissipation
due to the load circuit:
PD = [(22 + 0.61F) + [((1550-2.7F)/Z) + (.0125FC)]N] x 1.1
