These inputs are normally wired to V
unconnected inputs at V
before all data sheet limits are achieved.
CY7B9911V:I
Where
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.
CY7B9911V should be tested one output at a time, output shorted for less than one second, less than 10% duty cycle. Room temperature only.
Total output current per output pair can be approximated by the following expression that includes device current plus load current:
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
