Notes

5. For more information see 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 glitch and the PLL may require an additional tLOCK time before all data sheet limits are achieved.

7. CY7B9911V must 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 is 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 is 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.)
