Notes:
5. See the last page of this specification for Group A subgroup testing information.
6. These inputs are normally wired to VCC, GND, or left unconnected (actual threshold voltages vary as a percentage of VCC). Internal termination resistors hold
unconnected inputs at VCC/2. If these inputs are switched, the function and timing of the outputs may glitch and the PLL may require an additional tLOCK 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: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
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.
