Notes:
5. See the last page of this specification for Group A su/jointfilesconvert/478599/bgroup testing information.
6. These inputs are normally wired to V
CC
, GND, or left unconnected (actual threshold voltages vary as a percentage of V
CC
). Internal termination resistors hold
unconnected inputs at V
CC
/2. If these inputs are switched, the function and timing of the outputs may glitch and the PLL may require an additional t
LOCK
time
before all data sheet limits are achieved.
7. CY7B9911V should be tested one output at a time, output shorted for less than one second, less than 10% duty cycle. Room temperature only.
8. Total output current per output pair can be approximated by the following expression that includes device current plus load current:
CY7B9911V:I
CCN
= [(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
9. Total power dissipation per output pair can be approximated by the following expression that includes device power dissipation plus power dissipation due to
the load circuit:
PD = [(22 + 0.61F) + [[(1550 + 2.7F)/Z) + (.0125FC)]N] x 1.1
See note 8 for variable definition.
10. Applies to REF and FB inputs only. Tested initially and after any design or process changes that may affect these parameters.
