Description
V
CCP
PLL Power
—V
CCP
is V
CC
dedicated for 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. There is one V
CCP
input.
V
CCQL
(4)
Quiet Core (Low) Power—
V
CCQL
is an isolated power for the internal processing logic.
This input must be tied externally to all other chip power inputs. The user must provide
adequate external decoupling capacitors. There are four V
CCQL
inputs.
V
CCQH
(4)
Quiet External (High) Power
—V
CCQH
is a quiet power source for I/O lines. This input
must be tied externally to all other chip power inputs. The user must provide adequate
decoupling capacitors. There are four V
CCQH
inputs.
V
CCA
(4)
Address Bus Power
—V
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. The user
must provide adequate external decoupling capacitors. There are four V
CCA
inputs.
V
CCD
(1)
Data Bus Power
—V
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 is one V
CCD
inputs.
V
CCC
(1)
Bus Control Power
—V
CCC
is an isolated power for the bus control I/O drivers. This
input must be tied externally to all other chip power inputs. The user must provide ade-
quate external decoupling capacitors. There is one V
CCC
inputs.
V
CCS
(3)
SHI and ESAI
—V
CCS
is an isolated power for the SHI and ESAI. This input must be
tied externally to all other chip power inputs
L
. The user must provide adequate external
decoupling capacitors. There are three V
CCS
inputs.
