CALCULATING POWER DISSIPATION
With ICC(f) taken from Figure 1, the maximum power dissipation (PT) of the IDT72V3611 may be calculated by:
PT = VCC x ICC(f) +
Σ(CL x (VOH - VOL)2 x fO)
N
where:
N
=
number of outputs = 36
CL
=
output capacitance load
fO
=
switching frequency of an output
VOH
=
output high-level voltage
VOL
=
output low-level voltage
When no read or writes are occurring on this device, the power dissipated by a single clock (CLKA or CLKB) input running at frequency fS is
calculated by:
PT = VCC x fS x 0.025 mA/MHz
