Power input descriptions for the DSP56309 are listed in
Table 2-2
Power Inputs
Power Name
Description
V
CCP
PLL Power
ÑV
CCP
is power dedicated for phase-locked loop (PLL) use.
The voltage should be well regulated, and the input should be provided
with an extremely low impedance path to the V
CC
power rail. V
CCP
should be bypassed to GND
P
by a stabilizing capacitor located as close
as possible to the chip package. There is one V
CCP
input.
V
CCQL
(4)
Quiet Core (Low) Power
ÑV
CCQL
is an isolated power for the core
processing logic. This input must be isolated externally from all other
chip power inputs. The user must provide adequate external decoupling
capacitors. There are four V
CCQL
inputs.
V
CCQH
(3)
Quiet External (High) Power
ÑV
CCQH
is a quiet power source for I/O
lines. This input must be tied externally to all other chip power inputs,
except V
CCQL
. The user must provide adequate external decoupling
capacitors. There are three V
CCQH
inputs.
V
CCA
(3)
Address Bus Power
ÑV
CCA
is an isolated power for sections of the
address bus I/O drivers. This input must be tied externally to all other
chip power inputs
except V
CCQL
. The user must provide adequate
external decoupling capacitors. There are three V
CCA
inputs.
V
CCD
(4)
Data Bus Power
ÑV
CCD
is an isolated power for sections of the data bus
I/O drivers. This input must be tied externally to all other chip power
inputs. The user must provide adequate external decoupling capacitors.
There are four V
CCD
inputs.
V
CCC
(2)
Bus Control Power
ÑV
CCC
is an isolated power for the bus control I/O
drivers. This input must be tied externally to all other chip power inputs
except V
CCQL
. The user must provide adequate external decoupling
capacitors. There are two V
CCC
inputs.
V
CCH
Host Power
ÑV
CCH
is an isolated power for the HI08 I/O drivers. This
input must be tied externally to all other chip power inputs
except
V
CCQL
. The user must provide adequate external decoupling capacitors.
There is one V
CCH
input.
