DSP56366 Advance Information
4-3
Because the DSP output signals have fast rise and fall times, PCB trace lengths should be minimal.
This recommendation particularly applies to the address and data buses as well as the IRQA,
IRQB, IRQC, IRQD, TA and BG pins. Maximum PCB trace lengths on the order of 15 cm
(6 inches) are recommended.
Consider all device loads as well as parasitic capacitance due to PCB traces when calculating
capacitance. This is especially critical in systems with higher capacitive loads that could create
higher transient currents in the VCC and GND circuits.
All inputs must be terminated (i.e., not allowed to float) using CMOS levels, except for the three
pins with internal pull-up resistors (TMS, TDI, TCK).
Take special care to minimize noise levels on the VCCP and GNDP pins.
If multiple DSP56366 devices are on the same board, check for cross-talk or excessive spikes on
the supplies due to synchronous operation of the devices.
RESET must be asserted when the chip is powered up. A stable EXTAL signal must be supplied
while RESET is being asserted.
At power-up, ensure that the voltage difference between the 5 V tolerant pins and the chip VCC
never exceeds 3.95 V.
POWER CONSUMPTION CONSIDERATIONS
Power dissipation is a key issue in portable DSP applications. Some of the factors which affect current
consumption are described in this section. Most of the current consumed by CMOS devices is alternating
current (ac), which is charging and discharging the capacitances of the pins and internal nodes.
Current consumption is described by the following formula:
where
C = node/pin capacitance
V = voltage swing
f = frequency of node/pin toggle
Example 1 Current Consumption
For a Port A address pin loaded with 50 pF capacitance, operating at 3.3 V, and with a 120 MHz clock, toggling at its
maximum possible rate (60 MHz), the current consumption is
