power-supply sequencing
TI DSPs do not require specific power sequencing between the core supply and the I/O supply. However,
systems should be designed to ensure that neither supply is powered up for extended periods of time if the other
supply is below the proper operating voltage.
system-level design considerations
System-level design considerations, such as bus contention, may require supply sequencing to be
implemented. In this case, the core supply should be powered up at the same time as, or prior to (and powered
down after), the I/O buffers. This is to ensure that the I/O buffers receive valid inputs from the core before the
output buffers are powered up, thus, preventing bus contention with other chips on the board.
power-supply design considerations
For systems using the C6000
DSP platform of devices, the core supply may be required to provide in excess
of 2 A per DSP until the I/O supply is powered up. This extra current condition is a result of uninitialized logic
within the DSP(s) and is corrected once the CPU sees an internal clock pulse. With the PLL enabled, as the
I/O supply is powered on, a clock pulse is produced stopping the extra current draw from the supply. With the
PLL disabled, as many as five external clock cycle pulses may be required to stop this extra current draw. A
normal current state returns once the I/O power supply is turned on and the CPU sees a clock pulse. Decreasing
the amount of time between the core supply power up and the I/O supply power up can minimize the effects
of this current draw.
A dual-power supply with simultaneous sequencing, such as available with TPS563xx controllers or PT69xx
plug-in power modules, can be used to eliminate the delay between core and I/O power up [see the
Using the
TPS56300 to Power DSPs
application report (literature number SLVA088)]. A Schottky diode can also be used
to tie the core rail to the I/O rail, effectively pulling up the I/O power supply to a level that can help initialize the
logic within the DSP.
Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize
inductance and resistance in the power delivery path. Additionally, when designing for high-performance
applications utilizing the C6000
platform of DSPs, the PC board should include separate power planes for
core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors.
